| 1 | The complete reference genome for grapevine (Vitis vinifera L.) genetics and breeding显示文摘Grapevine is one of the most economically important crops worldwide.However,the previous versions of the grapevine reference genome tipically consist of thousands of fragments with missing centromeres and telomeres,limiting the accessibility of the repetitive sequences,the centromeric and telomeric regions,and the study of inheritance of important agronomic traits in these regions.Here,we assembled a telomere-to-telomere(T2T)gap-free reference genome for the cultivar PN40024 using PacBio HiFi long reads.The T2T reference genome(PN_T2T)is 69 Mb longer with 9018 more genes identified than the 12X.v0 version.We annotated 67%repetitive sequences,19 centromeres and 36 telomeres,and incorporated gene annotations of previous versions into the PN_T2T assembly.We detected a total of 377 gene clusters,which showed associations with complex traits,such as aroma and disease resistance.Even though PN40024 derives from nine generations of selfing,we still found nine genomic hotspots of heterozygous sites associated with biological processes,such as the oxidation–reduction process and protein phosphorylation.The fully annotated complete reference genome therefore constitutes an important resource for grapevine genetic studies and breeding programs. | Xiaoya Shi Shuo Cao Xu Wang Siyang Huang Yue Wang Zhongjie Liu Wenwen Liu Xiangpeng Leng Yanling Peng Nan Wang Yiwen Wang Zhiyao Ma Xiaodong Xu Fan Zhang Hui Xue Haixia Zhong Yi Wang Kekun Zhang Amandine Velt Komlan Avia Daniela Holtgräwe Jérôme Grimplet JoséTomás Matus Doreen Ware Xinyu Wu Haibo Wang Chonghuai Liu Yuling Fang Camille Rustenholz Zongming Cheng Hua Xiao Yongfeng Zhou | 2023 | Horticulture Research2023，10，5： | 3 |
| 2 | Anatomical berry characteristics during the development of grape berries with different shapes显示文摘The aim of this study was to characterize the changes in berry anatomy during the development of grape(Vitis vinifera L.,and Vitis vinifera×Vitis labrusca)with different shapes.Paraffin sectioning was used to examine the structural parameters of the cells.The results revealed that,with the development of berries,the transverse and longitudinal diameters of the flesh cells gradually increased,revealing certain regularity.However,the transverse and longitudinal diameters of the epidermal and sub-epidermal cells were different between varieties,reflecting the specificity of the varieties.The growth of the transverse and longitudinal diameters of the berries was found to be completed in the early stage of development.A combination of correlation analysis and size analysis for each cell layer revealed that,due to the small crosssectional area of the epidermal and sub-epidermal cells,the influence of these cells on the transverse and the longitudinal diameters of the berries would be small.In conclusion,the longitudinal and transverse diameters of the grape berries were mainly determined by the longitudinal and transverse diameters of the flesh cells.The different shapes of the grape berries could mainly be attributed to the different growth rates of the flesh cells in the longitudinal and transverse directions.These different rates of growth led to different lengths and widths of the berry. | Chuan Zhang Xiucai Fan Chonghuai Liu Jinggui Fang | 2021 | Horticultural Plant Journal2021，7，4： | 1 |

| 6 | QTL mapping for berry shape based on a high-density genetic map constructed by whole-genome resequencing in grape显示文摘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. | Yandi Wu Yong Wang Xiucai Fan Ying Zhang Jianfu Jiang Lei Sun Qiangwei Luo Feng Sun Chonghuai Liu | 2023 | Horticultural Plant Journal2023，9，4： | 0 |
| 7 | Mining candidate genes of grape berry cracking based on high density genetic map显示文摘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. | Chuan Zhang Liwen Cui Chonghuai Liu Xiucai Fan Jinggui Fang | 2023 | Horticultural Plant Journal2023，9，4： | 0 |
| 8 | QTL detection and candidate gene analysis of grape white rot resistance by interspecific grape (Vitis vinifera L. × Vitis davidii Foex.) crossing显示文摘Grape white rot,a devastating disease of grapevines caused by Coniella diplodiella(Speg.)Sacc.,leads to significant yield losses in grape.Breeding grape cultivars resistant to white rot is essential to reduce the regular use of chemical treatments.In recent years,Chinese grape species have gained more attention for grape breeding due to their high tolerance to various biotic and abiotic factors along with changing climatic conditions.In this study,we employed whole-genome resequencing(WGR)to genotype the parents of‘Manicure Finger’(Vitis vinifera,female)and‘0940’(Vitis davidii,male),along with 101 F1 mapping population individuals,thereby constructing a linkage genetic map.The linkage map contained 9337 single-nucleotide polymorphism(SNP)markers with an average marker distance of 0.3 cM.After 3 years of phenotypic evaluation of the progeny for white rot resistance,we confirmed one stable quantitative trait locus(QTL)for white rot resistance on chromosome 3,explaining up to 17.9%of the phenotypic variation.For this locus,we used RNA-seq to detect candidate gene expression and identified PR1 as a candidate gene involved in white rot resistance.Finally,we demonstrated that recombinant PR1 protein could inhibit the growth of C.diplodiella and that overexpression of PR1 in susceptible V.vinifera increased grape resistance to the pathogen. | Peng Li Xibei Tan Ruitao Liu Faiz Ur Rahman Jianfu Jiang Lei Sun Xiucai Fan Jihong Liu Chonghuai Liu Ying Zhang | 2023 | Horticulture Research2023，10，5： | 0 |
