Qian Xu, co-first author of  Strigolactone and Karrikin Signaling Pathways Elicit Ubiquitination and Proteolysis of SMXL2 to Regulate Hypocotyl Elongation in Arabidopsis thaliana

Current Position: Currently unemployed

Education: PhD in Genetics at the Institute of Genetics and Developmental Biology, Chinese Academy of Sciences (IGDB, CAS). B.Sc. in Biotechnology at Sun Yat-sen University

Non-scientific Interests: travel and gardening

Brief bio: Acquiring the knowledge and experimental skills of the interaction between rhizobia and legume, my first scientific research training was achieved in Prof. Christian Staehelin’s lab during college. Subsequently, I started my PhD in Jiayang Li’s lab at IGDB, CAS from 2012. I worked on research projects about tryptophan-independent auxin biosynthesis, embryogenesis, mitochondria isolation, and also strigolactones (SLs) signaling in Arabidopsis. I want to know the roles of  SLs and karrikins (KARs) in regulation of hypocotyl elongation and found that SLs inhibited hypocotyl elongation through SMXL2, whereas KARs inhibited hypocotyl elongation through SMAX1 and SMXL2.

个人简介：我在本科期间开始了我最早的科研训练，在中山大学Christian Staehelin教授实验室学习根瘤菌与豆科植物相互作用相关知识与实验技能。2012年开始在中国科学院遗传与发育生物学研究所李家洋实验室攻读博士学位。在博士期间，我以拟南芥为研究对象对非依赖于色氨酸的生长素合成途径、胚胎发育机制、线粒体分离以及独脚金内酯信号途径开展研究。我尝试解析独脚金内酯与karrikins抑制拟南芥下胚轴伸长的作用机制，发现独脚金内酯主要通过SMXL2抑制拟南芥下胚轴的伸长，而karrikins则通过SMAX1和SMXL2抑制下胚轴的伸长。
