Brief bio: I have a long-term interest in understanding the molecular mechanisms of meiosis and meiotic recombination in higher eukaryotes. Since 2011 at Fudan University, I have been working on the meiotic recombination associated DNA synthesis. We refined the meiotic recombination model by integrating DNA replication required leading and lagging strand syntheses into the double strand break repair process. Meanwhile, I’m also interested in the epigenetic regulation mechanism, like small RNAs (sRNAs) on meiotic recombination regulation. Previously, we reported a substantial number of meiocyte-specific small RNA (ms-sRNA) loci in Arabidopsis. Most of them show meiotic recombination dependent, significantly enriched in genic regions and exhibiting positive correlation with meiocyte-preferential gene expression unrelated to DNA methylation. Here we provide the “Season 2” of our sRNA series. We found that the positive gene-ms-sRNA association is also conserved in soybean and analyzed the conservation and divergence of sRNAs in flowering plants. We are hoping to provide you our “sRNA Season 3 Story” in the coming future.

自我介绍：本人长期致力于研究高等真核生物减数分裂和重组的分子机制。从2011年在复旦大学攻读博士开始，系统研究了DNA合成在减数分裂重组中的功能。我们的工作揭示了前导链和后导链在双链断裂修复中的作用，完善了减数分裂重组模型。此外，本人也对包括小RNA在内的表冠遗传调控减数分裂重组的分子机制深有兴趣。我们前期的工作报道了拟南芥雄性减数分裂细胞特异表达的小RNA倾向于在基因区域富集；与DNA甲基化不相关；却和减数分裂优先表达基因正相关；并且大部分位点依赖于减数分裂重组。本文为这一工作的延续，我们在大豆中也证实了拟南芥中存在的基因表达与减数分裂特异富集的小RNA正相关；并且分析了小RNA在不同开花植物中的特异性和保守性。希望能够在不久的将来带给大家更多的sRNA参与减数分裂的故事。
