Brief bio: During the years 2011 to 2017, I pursued post-graduate training in the filed of meiosis at the Institute of Genetics and Developmental Biology (IGDB) under the supervision of Prof. Zhukuan Cheng. My study focused on the relationship between telomere bouquet and homologous recombination in rice meiosis, aiming to unraveling the molecular basis of recombination and realizing the genetic control of recombination frequency in crop breeding. We identified a meiosis-specific F-box protein ZYGO1 that regulates telomere clustering to promote homologous pairing and recombination during meiosis. After obtaining my PhD. Degree in 2017, I worked as a post doctor in IGDB to further my knowledge in meiotic recombination. We found that OsSUN1 and OsSUN2 have partially redundant roles in rice meiosis and they function as key linkages between bouquet formation and meiotic recombination. I hope that there will be more interesting and meaningful discoveries in my future scientific research career.

个人简介：自2011到2017年，我在中国科学院遗传与发育生物学研究所减数分裂领域进行硕博连读，我的导师是程祝宽研究员。我主要的研究方向是以水稻为模式植物探究减数分裂过程中端粒聚集与同源重组的关系，以期解析重组的分子机制，进而在作物育种中实现重组频率的遗传调控。我们发现了一个减数分裂特异的F-box蛋白ZYGO1，证明它可以在减数分裂过程中通过调控端粒聚集促进同源染色体配对和重组。在2017年底，我获得了遗传学博士学位，随后留在本所继续在这一领域进行博士后研究。我们发现OsSUN1和OsSUN2这两个蛋白是减数分裂过程中端粒聚集与同源重组的关键桥梁，并且它们在水稻中的功能是部分冗余的。我希望在未来的研究生涯中可以有更多有意思和有意义的发现。
