The development of field dodder haustorium within stem tissues of the studied solanaceous plants was found to depend on the latter’s response to the former’s penetration. In hot pepper and tobacco, which showed a positive response, the haustorium was well developed and its searching hyphae established connections with their vascular tissues. However, potato and tomato showed a negative response and acquired different defense mechanisms against the parasitism of field dodder. In both of them, the field dodder haustorium and/or its searching hyphae exhibited distorted appearance and failed to establish connection with their vascular tissues. Thus, the tested solanaceous plant species could be classified as either compatible (hot pepper and tobacco) or incompatible (potato and tomato) hosts to field dodder.展开更多

In the conventional CDM (cold dark matter) model, dark matter and baryonic matter are interactive (compatible), so dark matter can contact baryonic matter. However, the conventional CDM model fails to account for the failure to detect dark matter by the contact (interaction) between dark matter and baryonic matter, the shortage of small galaxies, the abundance of spiral galaxies, the old age of large galaxies, and the formation of thin spiral galaxies. The non-interacting (incompatible cold dark matter) model can account for these observed phenomena. The five periods of baryonic structure development in the order of increasing non-interacting (incompatibility) are the free baryonic matter, the baryonic droplet, the galaxy, the cluster, and the supercluster periods.展开更多

CI can be rescued when Wolbachia-infected males mate with females infected with the same Wolbachia strain. However, the potential rescue mechanism of CI in the small brown planthopper Laodelphax striatellus is unclear. In this study, comparative transcriptome analysis was applied to explore the effect of Wolbachia on L. striatellus eggs. A total of 1387 differentially expressed genes were identified. RNA interference of 7 Wolbachia-upregulated key planthopper genes reduced egg reproduction, suggesting that Wolbachia might improve fecundity in L. striatellus by affecting these 7 genes. Suppressing the expression of another upregulated gene, NDUFA8 (encoding NADH dehydrogenase [ubiquinone] 1 α subcomplex subunit 8-like) by RNA interference significantly increased the mortality of early embryos without affecting the number of deposited eggs. Wolbachia infection upregulated the mRNA level of NDUFA8, and dsNDUFA8 treatment of Wolbachia-infected females recreated CI-like symptoms, suggesting that NDUFA8 is associated with the rescue phenotype. Because all L. striatellus populations worldwide are infected with Wolbachia, NDUFA8 is a potential pest control target.展开更多

Recent phylogenetic analyses as well as crossing experiments suggest that B. tabaci is a complex composed of 〉 20 cryptic species, but more crossing studies are required to examine the reproductive compatibility among the putative species and thus further clarify the systematics of this species complex. We conducted crossing experiments and behavioral observations to investigate the reproductive compatibility between the Mediterranean, Asia II 3, and Asia II 1 putative species ofB. tabaci collected from Zhejiang, China. Female progeny were never produced in inter-species crosses, demonstrating a lack of egg fertilization; while 55%-75% females were produced in all the intra-species treatments. Continuous behavioral observations showed that frequent courtship events occurred in both intra-species treatments and inter-putative species crosses. However, copulation events occurred only in the three intra-species treatments with one exception: that one copulation event occurred between Asia II 3 and Mediterranean in the crosses where two cohorts of females and males of different putative species were enclosed together in a small arena but were not allowed access to their intra-specific mates for a long period of time. These data demonstrated complete reproductive isolation between the Mediterranean, Asia II 3, and Asia II 1 putative species, and further showed that the isolation is due to lack of copulation. Demonstration of reproductive isolation between the Mediterranean and two indigenous putative species from China provides further evidence for the existence of cryptic species within the B. tabaci complex.展开更多

Due to the genetic instability occurring during carcinogenesis the glycosyltransferases may suffer from posttranslation sequence modification. The author describes 2 autopsy cases, where in the background of the unusual metastatic tumor presentation, incompatible blood group antigenic determinants have been demonstrated using blood group specific lectins and monoclonal antibodies (mAb). In the first case, reported here, a 10-year-old girl developed an acute myeloid leukemia and died in a septic endotoxin shock after successful cytostatic treatment of a juvenile signet ring cell cancer of her colon. At autopsy there were no signs of tumor except bilateral apple-sized mucinous ovarian (Krukenberg) metastases. While she had erythrocyte phenotype of blood group A, the signet ring adenocarcinoma cells expressed blood group B incompatible antigenic determinants with lectin/mAb. In the second case, the autopsy of a 78-year-old female resulted in no macroscopic tumor sign except a moderately enlarged, ham hard spleen. Light microscopy revealed adenocarcinomatous infiltration in the splenic sinusoids. The patient had blood group O, while the metastatic cells in the spleen reacted with Breast Carcinoma Antigen (BioGenex) and incompatible anti-B Banderiaeasimplicifolia agglutinin I and anti-B mAb. It proved to be a case of an occult, completely regressed breast cancer. Based on these observations the expression of tumor specific incompatible blood group antigens might occur from time to time, mostly in adenocarcinomas. Accordingly, blood group-based specific immuno-oncotherapy could be considered in some cancer cases.展开更多

文摘Strong genetic incompatibilities exist between two primary rice subspecies,indica and japonica.However,the wild ancestors of rice,O.nivara Sharma et Shastry and O.rufipogon Griff.,are genetically compatible.How this genetic incompatibility became established has not been clearly elucidated.To provide insights into the process,we analyzed a pair of hybrid sterility genes in rice,DOPPELGANGER 1(DPL1)and DOPPELGANGER 2(DPL2).Either of the two loci can have one defective allele(DPL1-and DPL2-).Hybrid pollen carrying both DPL1-and DPL2-alleles is sterile.To explore the origination of DPL1-and DPL2-,we sequenced the DPL1 and DPL2 genes of 811 individual plants,including Oryza sativa(132),O.nivara(296)and O.rufipogon(383).We then obtained 20 DPL1 and 34 DPL2 sequences of O.sativa from online databases.Using these sequences,we analyzed the genetic and geographic distribution patterns of DPL genes in modern rice and its wild ancestors.Compared with the ancestral populations,DPL1-and DPL2-showed reduced diversity but increased frequency in modern rice.We speculated that the diversity reduction was due to a historic genetic bottleneck,and the frequency had likely increased because the defective alleles were preferred following this artificial selection.Such results indicated that standing variances in ancestral lines can lead to severe incompatibilities among descendants.Haplotype analysis indicated that the DPL1-haplotype of rice emerged from an O.nivara population in India,whereas the DPL2-haplotype emerged from O.rufipogon in South China.Hence,the evolutionary history of DPLs conforms to the presumed multiple domestication events of modern rice.

文摘The non-flammability and high oxidation stability of sulfolane(SL)make it an excellent electrolyte candidate for lithium-ion batteries(LIBs).However,its incompatibility with graphitic anode prevents the realization of these advantages.To understand how this incompatibility arises on molecular level so that it can be suppressed,we combined theoretical calculation and experimental characterization and reveal that the primary Li^(+) solvation sheath in SL is depleted of fluorine source.Upon reduction,SL in such fluorine-poor solvation sheath generates insoluble dimer with poor electronic insulation,hence leading to slow but sustained parasitic reactions.When fluorine content in Li^(+)-SL solvation sheath is increased via salt concentration,a high stability LiF-rich interphase on graphite can be formed.This new understanding of the failure mechanism of graphite in SL-based electrolyte is of great significance in unlocking many possible electrolyte solvent candidates for the high-voltage cathode materials for next-generation LIBs.

文摘The cytoplasmic incompatibility in the field population of Culex pipiens complex from China and Japan was studied. The results of the crossing experiments between 11 different strains suggest that some Japanese strains might be possible to be used for control Chinese strains by using male sterile technique, and the heavy infection of wolbachiae in mosquitoes may have some relations with the cytoplasmic incompatibility in the field population of Cx. pipiens complex.
文摘Four solanaceous plant species, namely hot pepper (Capsicum frutescensL.), potato (Solanum tuberosumL.), tobacco (Nicotiana tabacumL.) and tomato (Lycopersicon esculentumMiller) were anatomically screened for compatibility/incompatibility to field dodder (Cuscuta campestrisYuncker, Cuscutaceae). The development of field dodder haustorium within stem tissues of the studied solanaceous plants was found to depend on the latter’s response to the former’s penetration. In hot pepper and tobacco, which showed a positive response, the haustorium was well developed and its searching hyphae established connections with their vascular tissues. However, potato and tomato showed a negative response and acquired different defense mechanisms against the parasitism of field dodder. In both of them, the field dodder haustorium and/or its searching hyphae exhibited distorted appearance and failed to establish connection with their vascular tissues. Thus, the tested solanaceous plant species could be classified as either compatible (hot pepper and tobacco) or incompatible (potato and tomato) hosts to field dodder.
文摘The paper derives the galaxy evolution by the non-interacting (incompatibility) between dark matter and baryonic matter in terms of the short-range separation between dark matter and baryonic matter, so dark matter cannot contact baryonic matter. In the conventional CDM (cold dark matter) model, dark matter and baryonic matter are interactive (compatible), so dark matter can contact baryonic matter. However, the conventional CDM model fails to account for the failure to detect dark matter by the contact (interaction) between dark matter and baryonic matter, the shortage of small galaxies, the abundance of spiral galaxies, the old age of large galaxies, and the formation of thin spiral galaxies. The non-interacting (incompatible cold dark matter) model can account for these observed phenomena. The five periods of baryonic structure development in the order of increasing non-interacting (incompatibility) are the free baryonic matter, the baryonic droplet, the galaxy, the cluster, and the supercluster periods.

文摘Incompatible measurements are of fundamental importance to re-vealing the peculiar features of quantum theory,and are also use-ful resources in various quantum information tasks.In this work,we investigate the quantum incompatibility of mutually unbiased bases(MUBs)within the operational framework of quantum resource the-ory,and report an experimental validation via the task of state dis-crimination.In particular,we construct an experimentally friendly witness to detect incompatible MUBs,based on the probability of cor-rectly discriminating quantum states.Furthermore,we prove that the noise robustness of MUBs can be retrieved from violating the above witness.Finally,we experimentally test the incompatibility of MUBs of dimensionality ranging from 2 to 4,and demonstrate that it is more robust to noise,as either the dimensionality of measurements or the number of MUBs increases.Our results may aid the exploration of the essential roles of incompatible measurements in both theoretical and practical applications in quantum information.

文摘The endosymbiont Wolbachia manipulates host reproduction by several strategies, one of the most important of which is cytoplasmic incompatibility (CI). CI can be rescued when Wolbachia-infected males mate with females infected with the same Wolbachia strain. However, the potential rescue mechanism of CI in the small brown planthopper Laodelphax striatellus is unclear. In this study, comparative transcriptome analysis was applied to explore the effect of Wolbachia on L. striatellus eggs. A total of 1387 differentially expressed genes were identified. RNA interference of 7 Wolbachia-upregulated key planthopper genes reduced egg reproduction, suggesting that Wolbachia might improve fecundity in L. striatellus by affecting these 7 genes. Suppressing the expression of another upregulated gene, NDUFA8 (encoding NADH dehydrogenase [ubiquinone] 1 α subcomplex subunit 8-like) by RNA interference significantly increased the mortality of early embryos without affecting the number of deposited eggs. Wolbachia infection upregulated the mRNA level of NDUFA8, and dsNDUFA8 treatment of Wolbachia-infected females recreated CI-like symptoms, suggesting that NDUFA8 is associated with the rescue phenotype. Because all L. striatellus populations worldwide are infected with Wolbachia, NDUFA8 is a potential pest control target.

文摘A composite liner consisting of a geomembrane(GMB)and a geosynthetic clay liner(GCL)can be compromised by inorganic contaminants because of a defective GMB.When the composite liner with defective GMB is exposed to aggressive leachate conditions,the neglect of the chemical incompatibility of the GCL can potentially result in an underestimation of the leakage rate and flux through the composite liner.This paper proposed a numerical investigation on the effect of chemical incompatibility of GCL on the barrier performance of the composite liner with hole defect.Four cases with leachate solutions having varied cation valencies and ionic strengths were analyzed,in which the hydraulic conductivity of GCL was concentrationdependent.Both the effect of the chemical incompatibility of GCL and the mechanisms were analyzed.The incompatibility of GCL resulted in significant increases in leakage rate and flux through the composite liner by factors of up to 4.9 and 5.0,respectively.The incompatibility-affected area in GCL is located within 0.1 m from the center of the hole in the GMB.The coupled increase in the hydraulic conductivity of GCL and pore water concentration impacts the flux and leakage in a short period of time.With GCL chemical incompatibility considered,advection may dominate the contaminant transport through GCL.

文摘Developing wide-temperature and high-safety lithium-ion batteries(LIBs)presents significant challenges attributed to the absence of suitable solvents possessing broad liquid range and non-flammability properties.γ-Butyrolactone(GBL)has emerged as a promising solvent;however,its incompatibility with graphite anode has hindered its application.This limitation necessitates a comprehensive investigation into the underlying mechanisms and potential solutions.In this study,we achieve a molecular-level understanding of the perplexing interphase formation process by employing in-situ spectroelectrochemical techniques and density function calculations.Our findings reveal that,even at high salt concentrations,GBL consistently occupies the primary Li^(+)solvation sheath,leading to extensive GBL decomposition and the formation of a high-impedance and inorganic-poor solid-electrolyte interphase(SEI)layer.Contrary to manipulating solvation structures,our research demonstrates that the utilization of filmforming additives with higher reduction potential facilitates the pre-establishment of a robust SEI film on the graphite anode.This approach effectively inhibits GBL decomposition and significantly enhances the battery's lifespan.This study provides the first reported intrinsic understanding of the unique GBLgraphite incompatibility and offers valuable insights for the development of wide-temperature and high-safety LIBs.

文摘The whitefly Bemisia tabaci has a global distribution and extensive genetic diversity. Recent phylogenetic analyses as well as crossing experiments suggest that B. tabaci is a complex composed of 〉 20 cryptic species, but more crossing studies are required to examine the reproductive compatibility among the putative species and thus further clarify the systematics of this species complex. We conducted crossing experiments and behavioral observations to investigate the reproductive compatibility between the Mediterranean, Asia II 3, and Asia II 1 putative species ofB. tabaci collected from Zhejiang, China. Female progeny were never produced in inter-species crosses, demonstrating a lack of egg fertilization; while 55%-75% females were produced in all the intra-species treatments. Continuous behavioral observations showed that frequent courtship events occurred in both intra-species treatments and inter-putative species crosses. However, copulation events occurred only in the three intra-species treatments with one exception: that one copulation event occurred between Asia II 3 and Mediterranean in the crosses where two cohorts of females and males of different putative species were enclosed together in a small arena but were not allowed access to their intra-specific mates for a long period of time. These data demonstrated complete reproductive isolation between the Mediterranean, Asia II 3, and Asia II 1 putative species, and further showed that the isolation is due to lack of copulation. Demonstration of reproductive isolation between the Mediterranean and two indigenous putative species from China provides further evidence for the existence of cryptic species within the B. tabaci complex.

文摘Mesorhizobium huakuii strain 7653R harbored two indigenous plasmids named pMH7653Ra and pMH7653Rb.The larger plasmid pMH7653Rb (symbiotic plasmid) was transferred to M.huakuii HN308SR harboring three plasmids: pMHHN308a,pMHHN308b and pMHHN308c,and HN3015SR harboring three plasmids: pMHHN3015a,pMHHN3015b and pMHHN3015c by tri-parent mating.Two stable indigenous plasmids,pMHHN308b and pMHHN308c of HN308SR,were co-eliminated due to the introduction of pMH7653Rb,and the transconjugant was named HN308SRN14.The results implied that pMH7653Rb and pMHHN308b,pMHHN308c were incompatible and might have been ascribed to the same incompatible group.The plasmid profiles of transconjugant HN3015SRN14 showed that the second largest plasmid pMHHN3015b of HN3015SR was cured due to the introduction of pMH7653Rb.The results also implied that pMH7653Rb and pMHHN3015b were incompatible.Results from plant nodulation tests showed that pMH7653Rb could only maintain the nodulation ability in transconjugant HN308SRN14 and its nodule number was more than that of wild strain HN308SR,but could not replace the nitrogen fixation effect of pMHHN308b and pMHHN308c.The plasmid cured mutant HN308SRN14D harboring only pMHHN308a formed null nodules that demonstrated pMHHN308a was relevant to nodulation ability.HN3015SRN14 harboring pMH7653Rb,pMHHN3015a and pMHHN3015c formed null nodules while HN3015SRN14D containing pMHHN3015a and pMHHN3015c lost the nodulation ability.The plasmid replication repC-like gene sequences were detected by a polymerase chain reaction from 7653R,HN308,HN3015,HN308SRN14 and HN3015SRN14.The repC gene sequence similarities of the strains tested attained 99%.

文摘In quantitative susceptibility mapping(QSM),the background field removal is an essential data acquisition step because it has a significant effect on the restoration quality by generating a harmonic incompatibility in the measured local field data.Even though the sparsity based first generation harmonic incompatibility removal(1GHIRE)model has achieved the performance gain over the traditional approaches,the 1GHIRE model has to be further improved as there is a basis mismatch underlying in numerically solving Poisson’s equation for the background removal.In this paper,we propose the second generation harmonic incompatibility removal(2GHIRE)model to reduce a basis mismatch,inspired by the balanced approach in the tight frame based image restoration.Experimental results shows the superiority of the proposed 2GHIRE model both in the restoration qualities and the computational efficiency.

文摘BACKGROUND Human immunodeficiency virus(HIV)-positive patients coinfected with hepatitis B virus(HBV)are eligible for liver transplantation(LT)in Africa and Southeast Asia,particularly China.However,the outcome of HIV-HBV coinfected patients referred for ABO-incompatible LT(ABOi-LT)is unknown.AIM To clarify the outcome of ABOi-LT for HIV-HBV coinfected patients with endstage liver disease(ESLD).METHODS We report on two Chinese HIV-HBV coinfected patients with ESLD who underwent A to O brain-dead donor LT and reviewed the literature on HIV-HBV coinfected patients treated with ABO-compatible LT.The pretransplantation HIV viral load was undetectable,with no active opportunistic infections.Induction therapy consisted of two sessions of plasmapheresis and a single dose of rituximab in two split doses,followed by an intraoperative regimen of intravenous immunoglobulin,methylprednisolone,and basiliximab.Post-transplant maintenance immunosuppressive agents consisted of tacrolimus and mycophenolate mofetil,and prednisone.RESULTS At the intermediate-term follow-up,patients showed undetectable HIV viral load,CD4(+)T cell counts greater than 150 cells/μL,no HBV recurrence,and stable liver function.A liver allograft biopsy showed no evidence of acute cellular rejection.Both patients survived at 36-42 mo of follow-up.CONCLUSION This is the first report of ABOi-LT in HIV-HBV recipients with good intermediate-term outcomes,suggesting that ABOi-LT may be feasible and safe for HIV-HBV coinfected patients with ESLD.
文摘Patients with end-stage renal disease in Greece are facing long waiting times to receive a kidney transplant from a deceased donor.Living kidney donation offers a valuable alternative that provides optimal outcomes and significantly expands the donor pool but still remains relatively underutilised.Developments around the world in the field of kidney transplantation mandate a change in current practice to include additional options for living donation through paired exchange,antibody-incompatible transplantation and other strategies,following careful consideration of the cultural and ethical factors involved in these complex clinical decisions.An increase in living donation rates may be achieved in several ways,including targeted campaigning to overcome potential barriers.Educating clinicians on transplantation will prove as equally important as informing patients and prospective donors but requires training and resources.Adoption of established practices and implementation of new strategies must be tailored to the needs of the Greek donor and recipient population.Local beliefs about donation,perception of associated risk and other social characteristics must be considered in the design of future strategies.Facilitating living donation in a safe environment with appropriate donor and recipient education will form the solid foundation of a new era of kidney transplantation in Greece.

文摘In the service period,the instability of ballastless track bed are mostly related to the damage of interlayers which are mainly resulted from the incompatible thermal deformation of interlayers.The temperature field within the ballastless track bed shows significant non-uniformity due to the large difference in the materials of various structure layers,leading to a considerable difference in the force bearing of different structure layers.Unit Ballastless Track Bed(UBTB)is most significantly affected by temperature gradient.The thermal deformation of interlayers within UBTB follows the trend of ellipsoid-shape buckling under the effect of the temperature gradient,resulting in a variation of the contact relationship between structure layers and a significant periodic irregularity on the rail.When the train travels on the periodically irregular rail,the structure layers are locally contacted,and the contact zone moves with the variation of the wheel position.This wheel-followed local contact greatly magnifies the interlayer stress,causes interlayer damage,and leads to a considerable increase in the bending moment of the track slab.Continuous Ballastless Track Bed(CBTB)is most significantly affected by the overall temperature variation,which may cause damage to the joint in CBTB.Under the combined action of the overall temperature rise and the temperature gradient,the interlayer damage continuously expands,resulting in bonding failure between structural layers.The thermal force in the continuous track slabs will cause the up-heave buckling and the sudden large deformation of the track slab,and the loss of constraint boundary of the horizontal stability.For the design of a ballastless track structure,the change of bearing status and structural damage related to the incompatible thermal deformation of interlayers should be considered.
文摘Cancer cells with immunogenic properties having altered protein glycosylation, modified blood group substances have been widely studied. Due to the genetic instability occurring during carcinogenesis the glycosyltransferases may suffer from posttranslation sequence modification. The author describes 2 autopsy cases, where in the background of the unusual metastatic tumor presentation, incompatible blood group antigenic determinants have been demonstrated using blood group specific lectins and monoclonal antibodies (mAb). In the first case, reported here, a 10-year-old girl developed an acute myeloid leukemia and died in a septic endotoxin shock after successful cytostatic treatment of a juvenile signet ring cell cancer of her colon. At autopsy there were no signs of tumor except bilateral apple-sized mucinous ovarian (Krukenberg) metastases. While she had erythrocyte phenotype of blood group A, the signet ring adenocarcinoma cells expressed blood group B incompatible antigenic determinants with lectin/mAb. In the second case, the autopsy of a 78-year-old female resulted in no macroscopic tumor sign except a moderately enlarged, ham hard spleen. Light microscopy revealed adenocarcinomatous infiltration in the splenic sinusoids. The patient had blood group O, while the metastatic cells in the spleen reacted with Breast Carcinoma Antigen (BioGenex) and incompatible anti-B Banderiaeasimplicifolia agglutinin I and anti-B mAb. It proved to be a case of an occult, completely regressed breast cancer. Based on these observations the expression of tumor specific incompatible blood group antigens might occur from time to time, mostly in adenocarcinomas. Accordingly, blood group-based specific immuno-oncotherapy could be considered in some cancer cases.

文摘Background:The shortage of donor liver restricts liver transplantation(LT).Nowadays,donor liver with ABO blood group incompatibility between donor and recipient has become an option to expand the source of donor liver.Although it is now possible to perform ABO-incompatible(ABO-I)LT,antibody-mediated rejection(AMR)has been recognized as the primary cause of desperate outcomes after ABO-I LT.Anti-A/B antibody is the trigger of immune response to ABO-I LT graft injury.Therapeutic plasma ex-change(TPE)can quickly reduce the titer of plasma antibodies and effectively inhibit humoral immunity.Data sources:We searched PubMed and CNKI databases using search terms“therapeutic plasma ex-change”,“ABO-incompatible liver transplantation”,“ABO-I LT”,“liver transplantation”,“LT”,“antibody-mediated rejection”,and“AMR”.Additional publications were identified by a manual search of references from key articles.The relevant publications published before September 30,2020 were included in this review.Results:Different centers have made different attempts on whether to use TPE,when to use TPE and how often to use TPE.However,the control standard of lectin revision level is always controversial,the target titer varies significantly from center to center,and the standard target titer has not yet been estab-lished.TPE has several schemes to reduce antibody titers,but there is a lack of clinical trials that provide standardized procedures.Conclusions:TPE is essential for ABO-I LT.Hence,further research and clinical trials should be conducted to determine the best regimen for TPE to remove ABO antibodies and prevent AMR.

文摘Self-incompatibility(SI),which has recurred during the evolution of plants,is one of the most important cross-pollination mating systems.Three S-loci have been reported in Brassicaceae,namely,Arabidopsis lyrata(Al),Brassica(Br),and Leavenworthia alabamica(La)S-loci.Here,through multi-genomic comparative analysis of 20 species,we revealed that the most ancient S-locus was formed prior to the divergence of Brassicaceae lineage I and II.Itwas retained and inherited by Arabidopsis,as the Al S-locus in Brassicaceae lineage I.Furthermore,we found that the Br S-locus,which has been widely used in the breeding of Brassica crops to generate hybrid seeds,was formed through segmental translocation(ST)in the hexaploid ancestor of Brassica in Brassicaceae lineage II.The Br S-locus was evolved through a ST from one of the triplicated ancestral S-locus paralogs in the Brassica hexaploidy ancestor,while the other two S-locus paralogs were lost.Together with the previous discovery that the La S-locus was formed through a secondary origin in Brassicaceae lineage I,we conclude the monophyletic origin of Al and Br S-loci and clarify the evolutionary route of S-loci in the Brassicaceae family.Our findings will contribute to evolutionary studies and breeding applications of the S-locus in Brassicaceae.
