Brief bio: I joined Prof. Minmin Miao’s group at Yangzhou University since 2016. My research is mainly focused on how cucumber balancing the assimilate partitioning between its source and sink to get optimal yield. Our experiments indicate that cucumber stachyose synthase, the key enzyme for assimilate biosynthesis, is down-regulated in mesophyll cells and up-regulated in vasculature tissues when the plant carries a fruit. This synergetic regulation reduces sugar storage in mesophyll tissue and promotes assimilate export from the leaf. In the future, I will continue to explore more mechanisms of cucumber source-sink regulation.

个人简介：我从2016年加入扬州大学缪旻珉教授团队攻读研究生，我的课题主要是研究黄瓜如何调节源-库之间同化物的分配，以获得最佳产量。研究表明，黄瓜水苏糖合成酶（CsSTS）是同化物合成的关键酶，当黄瓜结果时，CsSTS在叶肉细胞中下调，同时在维管束中上调。这种协同调节减少了叶肉组织中糖的含量，并促进同化物的输出。未来，我将继续探索黄瓜源-库调控间的更多机理。
