Brief bio: I came to Shanghai Institute of Plant Physiology and Ecology to study for my Ph.D. degree in 2016. I was lucky to join Prof. Yijing Zhang’s Lab after rotation. My work focused on the regulatory differentiation between wheat subgenomes. Common wheat has an extremely large and complex genome which is formed by interspecific hybridization of three different diploid species. Comparing to its ancestors, common wheat has a wider range of adaptations to the environment, which is resulted from the convergence of subgenomes previously adapted to different environments. The specificity encoded in wheat genome determining the subgenome-divergent spatio-temporal regulation has been largely unexplored, which is hampered by the considerable size and complexity of the genome. Therefore, we analyzed the epigenome and transcriptome data in different growing stages and under different abiotic stress and found that subgenome divergence is regulated by coordinated interplay between RE sequence contexts, epigenetic factors, and transcription factors.

个人简介：2016年，我来到上海植物生理生态研究所攻读博士学位，经过轮转后幸运地加入了张一婧老师课题组。研究生期间我的工作主要研究小麦亚基因组之间的调控分化。普通小麦拥有庞大而复杂的基因组，它是由三个异源多倍体经过两次杂交和多倍化之后形成的。相比于它的祖先种，普通小麦对环境的适应性更广泛，这被归因于三个亚基因组对不同环境有不同适应性。由于小麦基因组庞大而复杂，对小麦亚基因组时空调控特异性的研究一直未见进展。于是，我们通过分析不同生长发育时期、不同非生物胁迫处理下的表观组和转录组数据，揭示了普通小麦亚基因组分化受到序列背景、表观遗传因子和转录因子之间的共同调控。
