Despite its economic value, there is no information on its genome sequence. Here, we used the Illumina platform to determine the seed transcriptome of E.mollis to identify the genes related to Ve biosynthesis and potential simple sequence repeat(SSR) markers. In total, 100,999 unigenes were obtained with an average length of 605 bp and N50 of 985 bp. Of these unigenes,52,256(51.7%) were annotated in at least one public database(NT, NR, PFAM, Swiss Prot, KOG, KO, and GO)in searches using blastn/x. The unigene annotation identified 15 unigenes encoding six enzymes(GGR, HPPD,HPT/VTE2, MPBQ-MT/VTE3, TC/VTE1, and c-TMT/VTE4) putatively involved in Ve biosynthesis. In addition,16,810 SSRs distributed in 14,057 unigenes were mined.Of these, 2820, 583, and 3423 SSRs were located in the 50–UTR, coding sequence(CDS), and 30–UTR regions,respectively, while the remaining 9984 SSRs had undetermined physical locations. The largest group of repeat motifs comprised mononucleotide repeats(70.76%), followed by dinucleotide(15.59%) and trinucleotide(12.10%)repeats. AG/CT(8.69%) and AAG/CTT(4.15%) were the main dinucleotide and trinucleotide repeats, respectively.Furthermore, 9597 SSR-specific primer pairs were designed. Among 100 primer pairs selected randomly to determine their usefulness, 53 proved to be efficient. To the our best of knowledge, this work is the first study of the E. mollis transcriptome and constitutes valuable genomics data for future genetic engineering studies to alter the amount of Ve. The identified potential EST-SSR markers can be used for population genetics studies and assistedbreeding of E. mollis. 展开更多

Leymus mollis,a wild relative of wheat,is very tolerant to salt stress,and has been considered as a valuable genetic resource for wheat breeding.However,the genetic basis for salt tolerance of this species is still largely unknown.In this study,de novo sequencing,assembly and analysis of L.mollis transcriptome in response to salt stress was performed.A total of 110,323 and 112,846 unigenes were generated for the NaCl-free(CK)and 180 mM NaCl-treated(CT)library,respectively.For the two libraries,73,414 unigenes were successfully annotated in five common protein databases,and 7521 differentially expressed genes(DEGs)between CK and CT libraries were identified.GO enrichment analysis of the DEGs showed that the significantly enriched GO terms were predominantly involved in environmental adaptation(including“response to abiotic stimulus”,“response to water deprivation”),regulation of signaling pathway(such as“regulation of abscisic acid mediated signaling pathway”,“regulation of cell communication”),and photosynthesis(including“response to light stimulus”,“photosynthesis,light harvesting”and“chlorophyll metabolic process”).KEGG pathway enrichment analysis showed that“mRNA surveillance pathway”,“RNA transport”and“plant hormone signal transduction”were predominantly enriched pathways,followed by several secondary metabolic pathways,photosynthesis,carbohydrate metabolism and lipid metabolism.In addition,DEGs related to osmotic stress,ion homeostasis and oxidative stress,including four dehydrins,five aquaporins,an LmNHX2 and several antioxidant enzymes or proteins genes,were found to be up-regulated in response to salt stress.These results will be helpful for further studies on the molecular mechanisms of salt responses in L.mollis. 展开更多

This study was carried out to assess the growth characteristics of Grewia moll&, Grewia tenax and Grewia villosa under the nursery and field conditions. Two experiments were conducted at the farm of the College of Natural Resources and Environmental Studies, University of Juba, Khartoum, Sudan. Randomized complete block design with three replications was used. Morphological and physiological factors were measured. Seedlings height, number of leaves, number of branches and sub-branches were different (P 〈 0.05) among the three species at the nursery stage and under field conditions. Collar diameter showed significant difference among the species under field conditions. Physiological factors exhibited more significant variations in the field than at the nursery stage. Variations in growth characteristics were attributed to genetics differences and different growth habit, while variations in physiological factors (photosynthesis and transpiration rate) were attributed to differences in leaf structure, size and number of stomatal pores. 展开更多

The aim of this study was to evaluate the anti-inflammatory and hepatoprotective effects of the total flavonoid C-glycosides isolated from Abrus mollis extracts(AME). In the anti-inflammatory tests, xylene-induced ear edema model in mice and carrageenan-induced paw edema model in rats were applied. The hepatoprotective effects of AME were evaluated with various in vivo models of acute and chronic liver injury, including carbon tetrachloride(CCl4)-induced hepatitis in mice, D-galactosamine(D-GalN)-induced hepatitis in rats, as well as CCl4-induced hepatic fibrosis in rats. In the acute inflammation experiment, AME significantly suppressed xylene-induced ear edema and carrageenan-induced paw edema, respectively. In the acute hepatitis tests, AME significantly attenuated the excessive release of ALT and AST induced by CCl4 and D-GalN. In CCl4-induced hepatic fibrosis model, AME alleviated liver injury induced by CCl4 shown by histopathological sections of livers and improved liver function as indicated by decreased liver index, serum ALT, AST, TBIL, and ALP levels and hydroxyproline contents in liver tissues, and increased serum ALB and GLU levels. These results indicated that AME possesses potent anti-inflammatory activity in acute inflammation models and hepatoprotective activity in both acute and chronic liver injury models. In conclusion, AME is a potential anti-inflammatory and hepatoprotective agent and a viable candidate for treating inflammation, hepatitis, and hepatic fibrosis. 展开更多

Pilger (NsNsXmXm, 2n = 28), a wild relative of common wheat, possesses many potentially valuable traits that could be transferred to common wheat during breeding programs. In this study, the karyotypic constitution of a wheat - L. mollis 3D(3Ns#1) disomic substitution line isolated from the F5 progeny of octoploid Tritileymus M842-16 x Triticum durum cv. D4286, which was designated as 10DM57, was determined using genomic in situ hybridization (GISH), fluorescent in situ hybridization (FISH), SSR markers, and EST- STS markers. Screening of mitosis and meiosis showed that 10DM57 had a chromosome karyotype of 2n = 42 =21Ⅱ. GISH indicated that 10DM57 was a line with 40 chromosomes from wheat and two of the Ns chromosomes from L. mollis, which formed a ring bivalent in pollen mother cells at metaphase I. FISH analysis showed that the chromosome 3D may be replaced by 3Ns#1 in 10DM57. DNA markers, including SSR and EST-STS primers, showed that the pair of wheat chromosome 3D in 10DM57 was substituted by the pair of chromosome 3Ns#t from L. mollis. Evaluation of the agronomic traits showed that, compared with its common wheat relative 7182, 10DM57 was resistant to leaf rust while the spike length and number of spikes per plant were improved significantly, which correlated with a higher wheat yield. The new germplasm, 10DM57, could be exploited as an intermediate material in wheat genetic and breeding programs. 展开更多

Wheat stripe rust, caused by Puccinia striiformis f. sp. tritici, is one of the most widely distributed and destructive fungal diseases worldwide. Since 1995, most Chinese wheat cultivars have lost their stripe rust resistance due to the subsequent emergence of the new races CYR30, CYR31, CYR32, and CYR33 (Han et al., 2010). Therefore, it is necessary to seek effective resistance genes and develop new resistance germ- plasm for wheat resistance breeding. 展开更多

Terpenoids are the largest class of natural products with complex structures and extensive bioactivities;their scaffolds are generated by diverse terpenoid synthases(TPSs)from a limited number of isoprenoid diphosphate precursors.Promiscuous TPSs play important roles in the evolution of terpenoid chemodiversity,but they remain largely unappreciated.Here,an extremely promiscuous terpenoid synthase(CcTPS1)of the TPS-b subfamily was cloned and functionally characterized from a leaf-specific transcriptome of the Lamiaceae plant Colquhounia coccinea var.mollis.CcTPS1 is the first sester-/di-/sesqui-/mono-TPS identified from the plant kingdom,accepting C_(25)/C_(20)/C_(15)/C_(10) diphosphate substrates to generate a panel of sester-/di-/sesqui-/mono-terpenoids.Engineered Escherichia coli expressing CcTPS1 produced three previously unreported terpenoids(two sesterterpenoids and a diterpenoid)with rare cyclohexanecontaining skeletons,along with four sesquiterpenoids and one monoterpenoid.Their structures were elucidated by extensive nuclear magnetic resonance spectroscopy.Nicotiana benthamiana transiently expressing CcTPS1 also produced the diterpenoid and sesquiterpenoids,demonstrating the enzyme’s promiscuity in planta.Its highly leaf-specific expression pattern combined with detectable terpenoid products in leaves of C.coccinea var.mollis and N.benthamiana expressing CcTPS1 suggested that CcTPS1 was mainly responsible for diterpenoid and sesquiterpenoid biosynthesis in plants.CcTPS1 expression and the terpenoid products could be induced by methyl jasmonate,suggesting their possible role in plant–environment interaction.CcTPS1 was localized to the cytosol and may differ from mono-TPSs in subcellular compartmentalization and substrate tolerance.These findings will greatly aid our understanding of plant TPS evolution and terpenoid chemodiversity;they also highlight the enormous potential of transcriptome mining and heterologous expression for the exploration of unique enzymes and natural products hidden in plants. 展开更多

This study was carried out to assess the leaves and fruits of Grewia mollis, Grewia tenax and Grewia villosa for their potentials to produce high nutritive value fodder under semi-arid conditions. The experiment was conducted at the farm of the College of Natural Resources and Environmental Studies, University of Juba-Khartoum-Sudan. Randomized Complete Block design with three replications was used. Proximate analysis was carried to estimate nutritive value, and mineral contents of leaves, seeds and fruit pulp of the three species. Results indicated significant difference (P ≤ 0.05) in nutritive value of the leaves among the three species; dry matter, ash, and acid detergent factor (ADF) kg/ha, while no significant difference was observed among the species in crude protein (CP) and nutrient detergent factor (NDF) kg/ha. Mineral contents of the leaves of the three species showed variations among the species and seasons. Seeds and fruit pulp were found to have considerable levels of nutrients and mineral contents. The nutritive value of the three species was higher in the rainy season compared to the dry season. The results of this study indicate that the three species can be introduced as a source of fodder in animal production farms and silvopastural systems. 展开更多
