Brief bio: I joined Prof. Guo Da-Long’s group in 2018 and have been working mainly on genetic variation in grapevine berry ripening under his supervision since then. This study investigated the population genetic characteristics and the distribution of conserved genetic segments (haplotypes) in the ‘Pearl of Csaba’ pedigree by whole-genome resequencing of the ‘Pearl of Csaba’ early-ripening grapevine pedigree population, combined with sequencing data from published late-ripening and wild grapevine germplasm. Further joint experiments related to selection signals and QTL loci associated with early-ripening traits identified several key genetic segments and candidate genes that may be involved in controlling variation in grapevine berry ripening, providing a theoretical basis and genetic resources for molecular breeding of early ripening grapevines. I have always been interested in the variation and evolution of agronomic traits in plants and will continue my research in this area in the future.

个人简介：我于2018年加入郭大龙教授课题组至今，在郭大龙教授的指导下主要从事葡萄果实成熟期的遗传变异研究。该研究通过对‘莎巴珍珠’早熟葡萄家系群体的全基因组重测序，并结合已公开的晚熟和野生葡萄种质的测序数据，调查了‘莎巴珍珠’家系的群体遗传学特征和保守遗传片段的分布；进一步联合与早熟性状有关的选择信号、QTL位点等相关试验鉴定到了多个可能参与控制葡萄果实成熟期变异的关键遗传片段和候选基因，为早熟葡萄的分子育种提供理论依据和基因资源。我一直对植物农艺性状的变异和进化很感兴趣，未来将继续从事这方面的研究工作。
