Brief bio: I joined Prof. Wangzhen Guo’s laboratory at Nanjing Agricultural University as a Ph.D. graduate student in 2014. I received a joint-PhD training in Prof. Li Li’s laboratory at Cornell University from 2019 to 2022. Now I continue my research on carotenoids as a postdoctoral research associate under the supervision of Prof. Li Li and Prof. Michael Mazourek at Cornell University. My research is mainly focused on revealing the molecular mechanisms of carotenoid metabolism in horticultural crops. In this study, we found that CmOR directly interacts with CmFBN1 to mediate CmFBN1 protein level and stimulate plastoglobule proliferation for carotenoid accumulation in chromoplasts of melon fruit.

目前职位：康奈尔大学综合植物科学学院植物育种与遗传学系博士后。

个人简介：2014年以硕博连读加入南京农业大学郭旺珍教授团队。2019年至2022年获中国国家留学基金委资助在美国康奈尔大学李莉教授实验室以联合培养博士的身份学习。目前以博士后身份在李莉教授和Mazourek教授实验室继续从事类胡萝卜素的相关研究。我的研究主要集中在揭示类胡萝卜素在作物中代谢的分子调控机制。在该项研究中，我们通过蛋白质组学鉴定到了一个在甜瓜果实中与类胡萝卜素积累相关的蛋白CmFBN1，解析了分子伴侣蛋白CmOR与CmFBN1直接相互作用以提高CmFBN1蛋白的稳定性，从而提高其蛋白水平并促进质体小球增殖分化，最终增加甜瓜果实中的有色体中的β-胡萝卜素积累。
