Preventive effect of kiwi berry(Actinidia arguta)on loperamide-induced constipation

Constipation is a common intestinal disease.Kiwi berries can effectively prevent constipation.However,studies have yet to be done to determine how kiwi berries prevent constipation.For two weeks,mice in this study were continually orally gavaged with kiwi berry,loperamide,or a combination of the 2.This study found that the kiwi group's feces had more water than the constipated mice.In addition,kiwi berries can speed up gastrointestinal transit(GI),shorten the time it takes to pass the first dark stool,and dramatically enhance body weight gain.In the interstitial cells of Caj al(ICC)cells and colon tissues,alterations in the protein expression of vasoactive intestinal peptide(VIP),cyclic adenosine monophosphate(cAMP),protein kinase A(PKA),and aquapcrin-3(AQP3)were found.At 3,6,and 12 h of ICC cells and mouse colon,the kiwi group's VIP,cAMP,PKA,and AQP3 protein expression levels were lower than those of the constipated mice.The kiwi berry can decrease the Firmicutes to Bacteroidetes ratio and boost the diversity and quantity of gut microbiota.By influencing the gut microbiota and VIP-cAMP-PKA-AQP3 signaling pathway,kiwi berries prevent constipation.

Impact of Different Rates of Nitrogen Supplementation on Soil PhysicochemicalProperties and Microbial Diversity in Goji Berry

Goji berry(Lycium barbarum L.)is substantially dependent on nitrogen fertilizer application,which can signifi-cantly enhance fruit yield and Goji berry industrial development in Ningxia,China.This study aimed to analyze the functions of differential nitrogen application rates including low(N1),medium(N2),and high(N3)levels in soil microbial community structure(bacterial and fungal)at 2 diverse soil depths(0-20,20-40 cm)through high-throughput sequencing technology by targeting 16S RNA gene and ITS1&ITS2 regions.All the observed physicochemical parameters exhibited significant improvement(p<0.05)with increased levels of nitrogen and the highest values for most parameters were observed at N2.However,pH decreased(p<0.05)gradually.The alpha and beta diversity analyses for bacterial and fungal communities’metagenome displayed more similarities than differences among all groups.The top bacterial and fungal phyla and genera suggested no obvious(p>0.05)differences among three group treatments(N1,N2,and N3).Furthermore,the functional enrichment analysis demonstrated significant(p<0.05)enrichment of quorum sensing,cysteine and methionine metabolism,and transcriptional machinery for bacterial communities,while various saprotrophic functional roles for fungal communities.Conclusively,moderately reducing the use of N-supplemented fertilizers is conducive to increasing soil nitrogen utilization rate,which can contribute to sustainable agriculture practices through improved soil quality,and microbial community structure and functions.

Mining candidate genes of grape berry cracking based on high density genetic map

Fruit cracking is a phenomenon in which the peel cracks during grape berry development,which seriously affects the yield and quality of the fruit.However,there are few studies on the mining of candidate genes related to berry cracking.In order to better understand the genetic basis of berry cracking,we used the results of previous quantitative trait locus(QTL)mapping,combined with field surveys of berry-cracking types and the berry-cracking rate,to mine candidate berry-cracking genes.The results showed that three identical QTL loci were detected in two years(2019 and 2020);and three candidate genes were annotated in the QTL interval.In mature berries,the expressions of the candidate genes were more abundant in the cracking-susceptible parent(‘Crimson Seedless’)than in the cracking-resistant parent(‘Muscat Hamburg’).Grape berry cracking is a complex trait controlled by multiple genes,mainly including genes encoding cellulose synthase–like protein H1,glucan endo-1,3-beta-glucosidase 12,and brassinosteroid insensitive 1-associated receptor kinase 1.The high expression of the candidate berry-cracking genes may promote the occurrence of berry cracking.This study helps elucidate the genetic mechanism of grape berry cracking.

QTL mapping for berry shape based on a high-density genetic map constructed by whole-genome resequencing in grape

Grape berry shape is an important agricultural trait.Clarifying its genetic basis is significant for cultivating grape varieties that meet market demands.However,the current study by forward genetics has not achieved in-depth results.Here,a high-density map was constructed to identify quantitative trait loci(QTLs)for berry shape.A total of 358709 polymorphic SNPs were obtained using whole-genome resequencing(WGS)based on 208 F2 individuals derived from round grape‘E42-6’and oblong grape‘Rizamat’.The 1635.65 cM high-density map was divided into 19 linkage groups with an average distance of 0.37 cM.Using this map,three significant QTLs for fruit shape index(ShI:ratio of berry length to berry width)identified over three years were mapped onto LG4 and LG5,including one stable QTL on Chr5 with the genomic region of 0.47–1.94 Mb.Combining with gene annotation and expression patterns based on RNA-seq data from two contrasting F2 individuals with round and oblong berry(their average ShI was 1.89 and 1.10,respectively)at four developmental stages,four candidate genes were selected from the above QTLs.They were mainly involved in DNA replication,cell wall modification,and phytohormone biosynthesis.Further analysis of RNA-seq data revealed that several important phytohormone synthesis and metabolic pathways were enriched based on differentially expressed genes(DEGs),which was consistent with the results of QTL mapping for genes related to plant hormone biosynthesis in the F2 population.Furthermore,a comparison of plant hormone content showed that there were significant differences in IAA and tZ content between the two contrasting F2 individuals at different developmental stages.Our findings provide molecular insights into the genetic variation in grape berry shape.Stable QTLs and their tightly linked markers offer the possibility of marker-assisted selection to accelerate berry shape breeding.

FvWRKY50 is an important gene that regulates both vegetative growth and reproductive growth in strawberry

The WRKY transcription factors play important roles in plant growth and resistance,but only a few members have been identified in strawberry.Here we identified a WRKY transcription factor,FvWRKY50,in diploid strawberry which played essential roles in strawberry vegetative growth,and reproductive growth.Knocking out FvWRKY50 by genome editing accelerated flowering time and leaf senescence but delayed anthocyanin accumulation in fruit.Further analysis showed that FvWRKY50 acted as a transcriptional repressor to negatively regulate the expression of flowering-and leaf senescence-related genes,including FvFT2,FvCO,FvFT3,and FvSAUR36.Notably,FvWRKY50 directly upregulated the expression of FvCHI and FvDFR by binding their promoter under normal conditions,but at low temperature FvWRKY50 was phosphorylated by FvMAPK3 and then induced protein degradation by ubiquitination,delaying anthocyanin accumulation.In addition,the homozygous mutant of FvWRKY50 was smaller while the biallelic mutant showed normal size.These new findings provide important clues for us to further reveal the regulatory mechanisms of strawberry growth and fruit ripening.

Chiral current regulation and detection of Berry phase in triangular triple quantum dots

Based on the hierarchical equations of motion(HEOM)calculation,we theoretically investigate the corresponding control of a triangular triple-quantum-dots(TTQD)ring which is connected to two reservoirs.We initially demonstrate by adding bias voltage and further adjusting the coupling strength between quantum dots,the chiral current induced by bias will go through a transformation of clockwise to counterclockwise direction and an unprecedented effective Hall angle will be triggered.The transformation is very rapid,with a corresponding characteristic time of 80-200 ps.In addition,by adding a magnetic flux to compensate for the chiral current in the original system,we elucidate the relationship between the applied magnetic flux and the Berry phase,which can realize direct measurement of the chiral current and reveal the magnetoelectric coupling relationship.

Berry texture QTL and candidate gene analysis in grape(Vitis vinifera L.)

Berry texture is a noteworthy economic trait for grape;however,the genetic bases and the complex gene expression and regulatory mechanism for the diverse changes in berry texture are still poorly understood.In this study,the results suggest that it is difficult to obtain high-mesocarp firmness(MesF)and high-pericarp puncture hardness(PPH)grape cultivars with high pericarp brittleness(PerB).The high-density linkage map was constructed using whole-genome resequencing based on 151 F1 individuals originating from intraspecific hybridization between the firm-flesh cultivar‘Red Globe’and soft-flesh cultivar‘Muscat Hamburg’.The total length of the consensus map was 1613.17 cM,with a mean genetic distance between adjacent bin markers of 0.59 cM.Twenty-seven quantitative trait loci(QTLs)for berry MesF,PPH,and PerB were identified in linkage groups(LGs)1,3,4,6,8,9,10,11,14,16,and 17,including twelve QTLs that were firstly detected in LGs 6,11,and 14.Fourteen promising candidate genes were identified from the stable QTL regions in LGs 10,11,14,and 17.In particular,VvWARK2 and VvWARK8 refer to chromosome 17 and are two promising candidate genes for MesF and PPH,as the VvWARK8 gene may increase pectin residue binding with WARK for high berry firmness maintenance and the allele for VvWARK2 carrying the‘CC’and‘GA’genotypes at Chr17:1836764 and Chr17:1836770 may be associated with non-hard texture grape cultivars.In addition,real-time quantitative polymerase chain reaction(RT-qPCR)verification revealed that the promising candidate transcription factor genes VvMYB4-like,VvERF113,VvWRKY31,VvWRKY1,and VvNAC83 may regulate cell wall metabolism candidate gene expression for grape berry texture changes.

The telomere-to-telomere gap-free reference genome of wild blueberry (Vaccinium duclouxii) provides its high soluble sugar and anthocyanin accumulation

Vaccinium duclouxii,endemic to southwestern China,is a berry-producing shrub or small tree belonging to the Ericaceae family,with high nutritive,medicinal,and ornamental value,abundant germplasm resources,and good edible properties.In addition,V.duclouxii exhibits strong tolerance to adverse environmental conditions,making it a promising candidate for research and offering wide-ranging possibilities for utilization.However,the lack of V.duclouxii genome sequence has hampered its development and utilization.Here,a high-quality telomere-to-telomere genome sequence of V.duclouxii was de novo assembled and annotated.All of 12 chromosomes were assembled into gap-free single contigs,providing the highest integrity and quality assembly reported so far for blueberry.The V.duclouxii genome is 573.67 Mb,which encodes 41953 protein-coding genes.Combining transcriptomics and metabolomics analyses,we have uncovered the molecular mechanisms involved in sugar and acid accumulation and anthocyanin biosynthesis in V.duclouxii.This provides essentialmolecular information for further research on the quality of V.duclouxii.Moreover,the high-quality telomere-to-telomere assembly of the V.duclouxii genome will provide insights into the genomic evolution of Vaccinium and support advancements in blueberry genetics and molecular breeding.

Short-Term Impact of Elemental Sulfur on Cranberry Nutrition and Crop Performance

Cranberry (Vaccinium macrocarpon Ait.) is an ammophilous plant grown on acid soils (pH 4.0 - 5.5). Elemental sulfur is commonly applied at a recommended rate of 1120 kg S ha−1 per pH unit to acidify cranberry soils, potentially impacting the plant mineral nutrition. The general recommendation may not fit all conditions encountered in the field. Our objective was to develop an equation to predict the sulfur requirement to reach pHwater of 4.2 to tackle nitrification in acidic cranberry soils varying in initial pH values, and to measure the effect of elemental sulfur on the mineral nutrition and the performance of cranberry crops. A 3-yr experiment was designed to test the effect of elemental sulfur on soil and tissue tests and on berry yield and quality. Four S treatments (0, 250, 500 and 1000 kg S ha−1) were established on three duplicated sites during two consecutive years. We ran soil, foliar tissue, berry tissue tests, and measured berry yield, size, anthocyanin content (TAcy), Brix, and firmness. Nutrients were expressed as centered log ratios to reflect nutrient interactions. Results were analyzed using a mixed model. Soil Ca decreased while soil Mn and S increased significantly (p ≤ 0.05). Sulfur showed no significant effects on nutrient balances in uprights. The S impacted negatively berry B balance, and positively berry Mn and S balances. A linear regression model relating pH change to S dosage and elapsed time (R2 = 0.53) showed that to reach pHwater of 4.2 two years after S application, 250 - 1000 kg S ha−1 could be applied depending on initial soil pH value. The stratification of surface-applied elemental S in the soil profile should be further examined in relation to plant rooting and nutrient leaching.

Intercellular Symplastic Connection and Isolation of the Unloading Zone in Flesh of the Developing Grape Berry

The ultrastructure and intercellular connection of the sugar unloading zone (i.e. the phloem in the dorsal vascular bundle and the phloem_surrounding the assimilate sink_cells) of grape ( Vitis vinifera× V. labrusca cv. Jingchao) berry was observed via transmission electron microscopy. The results showed that during the early developmental stages of grape berry, numerous plasmodesmata were found in the phloem between sieve element (SE) and companion cell (CC), between SE/CC complexes, between SE/CC complex and phloem parenchyma cell and in between phloem parenchyma cells, which made the phloem a symplastic integration, facilitating sugar unloading from sieve elements into both companion cells and phloem parenchyma cells via a symplastic pathway. On the contrary, there was almost no plasmodesma between phloem and its surrounding flesh photoassimilate sink_cells, neither in between the flesh photoassimilate sink_cells giving rise to a symplastic isolation both between phloem and its surrounding flesh photoassimilate sink_cells, as well as among the flesh photoassimilate sink_cells. This indicated that both the sugar unloading from phloem and postphloem transport of sugars should be mainly via an apoplastic pathway. During the ripening stage, most of the plasmodesmata between SE/CC complex and the surrounding phloem parenchyma cells were shown to be blocked by the electron_opaque globules, and a phenomenon of plasmolysis was found in a number of companion cells, indicating a symplastic isolation between SE/CC complex and its surrounding parenchyma cells during this phase. The symplastic isolation between the whole phloem and its surrounding photoassimilate sink_cells during the early developmental stages shifted to a symplastic isolation within the phloem during the ripening phase, and thus the symplastic pathway of sugar unloading from SE/CC complex during the early development stages should be replaced by a dominant apoplastic unloading pathway from SE/CC complex in concordance.
