Brief bio: Before I started my Ph.D. on plant science, I joined a lab focused on obesity. Soon, I realized that it was not a good choice. Compared with animals, I like plants more. These green organisms use chloroplasts to utilize light energy for chemical components synthesis. Later, I started my PhD program and worked on chloroplasts. By using the Arabidopsis lesion mimic mutant, lsd1 (lesion simulating disease 1), my PhD project tries to understand the role of chloroplast and find related molecular details about the initiation of cell death in lsd1. The project led to the discovery of SIGMA FACTOR BINDING POTEIN 1 (SIB1), a nucleus and plastid dual targeted protein. The work provides a novel link between chloroplast and nucleus in plant development and stress response. I hope to continue studying plant science and find more links about plant-environment interactions in the future, as I think I made a good choice.

个人简介：在本科阶段，我加入了一个研究肥胖症的研究组，可是，经过一段时间的学习，我发现比起动物，我更喜欢研究植物。因为这些神奇的绿色植物能够利用光和二氧化碳，生产碳水化合、水和氧气。于是，我决定在研究生阶段转行研究植物。研究生阶段主要的工作是利用模式植物拟南芥，研究叶绿体的功能。因为叶绿体不仅是光合作用的主要场所，也是植物感受外界环境刺激的重要感受器。拟南芥突变体lsd1经过一定时间的光周期，叶片会出现细胞死亡的症状。之前的研究猜测这个症状可能与叶绿体相关，但是其中的相关性并不清楚。我的博士课题研究发现一个具有细胞核和叶绿体双向定位的蛋白SIB1，能够通过上调光合作用相关的细胞核基因的表达，影响叶绿体中活性氧的积累，最终导致lsd1突变体产生细胞死亡。这项研究揭示了叶绿体与细胞核之间的紧密联系，以及叶绿体在调控植物发育过程中的重要作用。未来，我希望能继续从事植物科学方面的研究，探索植物如何感知外界环以及如何调节自身生长发育等问题。
