  研究方向

  团队研究方向主要为运用多组学的数据探讨植物在进化过程中的演变。具体包括:1)以目前基因组学信息匮乏的蕨类和石松类植物为研究对象,利用多组学数据相结合的分析方法,探讨陆地植物进化过程中重要器官的起源和进化机制;2)以群体遗传学理论为支撑,研究作物在驯化、扩散和培育过程中有害突变的变化。

 

  研究进展

  1)通过全基因组重测序揭示了玉米驯化时的瓶颈效应和扩散过程中经历的一系列奠基者效应,这些居群历史动态影响了有害突变在玉米居群中的分布;

  2)解析了玉米适应多个高海拔地区的平行进化现象;

  3)利用全基因组重测序数据探讨了有害突变在350个来自不同育种年代的玉米品种中的变化;

  4)通过居群转录组数据研究了杨树(Populus balsamifera)性别分化的遗传机制,并揭示了其适应高纬度气候的遗传表现。

  Research Interests

  Our research focuses on the genetic mechanism of plant evolution utilizing the data of multi-omics. It specifically includes: 1) to explore the origin and evolutionary mechanism of important organs in terrestrial plants with fern and lycophytes as the research subject; 2) to investigate the prevalence of deleterious mutations in the process of domestication, migration and breeding of crops employing population genetic methods.

 

  Major Achievements

  1) Through whole-genome resequencing, we unveiled the bottleneck effect of maize domestication and a series of founder effects during the process of range expansion. The population demography affected the prevalence of deleterious mutations in the maize population.

  2) We revealed the genetic mechanism of parallel highland adaptation in multiple maize populations;

  3) Using high depth whole-genome resequencing data, we explored the dynamics of deleterious mutations in 350 maize inbred lines across 60 years’ breeding history;

  4) We disclosed the genetic mechanism of sex differentiation in Populus balsamifera with employment of population transcriptomic data, and how adaptation to high latitude environments reshaped the transcriptomes of the species.
