Brief bio: I was lucky to join the group of Prof. Wei-Hua Wu at China Agricultural University to pursue my PhD degree. During my PhD, I focused on mechanisms how signals are conducted under low K+ stress in Arabidopsis. Through a screen of T-DNA mutants, an Arabidopsis low-K+-sensitive mutant myb59 was isolated and its shoots became yellow earlier than wild-type plants under low K+ stress. Further analyses suggest that MYB59 is involved in regulation of root-to-shoot K+/ NO3– co-translocation under LK conditions. As a transcription factor, MYB59 positively regulate NRT1.5 transcription and NRT1.5 as the down-stream target gene of MYB59. The MYB59-NRT1.5 pathway plays important roles in regulating the coordinated transport of K+ and NO3– from root to shoot in Arabidopsis.

科研经历简介：我有幸加入中国农业大学武维华教授课题组攻读博士学位。在读博期间，我致力于拟南芥低钾条件下信号转导的相关研究。通过表型筛选获得一个拟南芥低钾敏感突变体myb59。在低钾条件下myb59表现出冠部比野生型提前发黄的表型。进一步的研究表明，MYB59调控低钾条件下K+和NO3–从根向冠的转运过程。作为转录因子，MYB59正调控NRT1.5的转录，而且MYB59位于NRT1.5的上游。MYB59和NRT1.5这一转录调控通路在植物响应环境钾亏缺、调控钾/氮协同转运及根冠分配方面有重要作用。
