Brief bio:

I studied and finished my master’s thesis entitled “Genetic transformation of soybean with Bt toxin protein gene endowing insect resistance and safety evaluation of transgenic lines” at Northeast Agricultural University. In September 2016 I joined Pro. Jian-Feng Li’s lab at Sun Yat-Sen University to pursuit my doctoral degree in Botany and started my research on the role of receptor-like cytoplasmic kinase CDG1 in plant innate immunity. Under the guidance of my advisor, I found that CDG1 serves as a negative regulator of the pattern-triggered immunity (PTI) in Arabidopsis. CDG1 attenuates immune signal transduction and response by negatively regulating the protein accumulation of bacterial flagellin receptor FLS2 and fungal chitin receptor CERK1 through the MEKK1-dependent MPK4 cascade. Interestingly, I also found that AvrRpm1, an effector protein secreted into plant cells by Pseudomonas syringae, can hijack CDG1 to phosphorylate its host target RIN4 on multiple amino acid residues including Thr166, which will block flagellin signal transduction and cause plant susceptibility. This finding suggests a pathogenic mechanism of bacterial effectors that host immune regulators are hijacked to suppress host immunity. Here I would like to thank my advisor Pro. Jian-Feng Li for helpful instruction on my work. Although the process of scientific research is full of hardships, I never get tired of it. I have never seen the scene of Los Angeles at 4 am, but have seen the laboratory at every hour of one day. I am looking forward to devoting myself to academic research in plant molecular biology and make more achievements in the future.









我衷心感谢导师李剑峰教授对我多年的辛苦栽培。虽然通往科学发现的道路充满艰辛,但我乐此不疲。我虽然没有见过凌晨四点的洛杉矶,但我却见过一天之内每一个时刻的Li Lab。我愿意继续将我的汗水挥洒在科研道路上,并期待今后在学术上能够不断进步。
