Brief bio: During my undergraduate study at China Agricultural University, I developed a strong interest in plant pathogenic fungi. After my undergraduate in 2016, I was very honored to enter the laboratory of Prof. Wenxian Sun at China Agricultural University to pursue my doctorate. I performed research on the pathogenic mechanism of the Ustilaginoidea virens virulence effectors with the careful guidance of Prof. Wenxian Sun. In this study, we reported that U. virens secretes a new type of tyrosine phosphatase SCRE6 into host cells to suppress rice immunity at the initial stage of infection. SCRE6 could dephosphorylate and inhibit the degradation of the negative immune regulator mitogen-activated protein kinase 6 (OsMPK6) to promote U. virens infection. We hoped our study could provide a theoretical basis for rice disease resistance breeding and green prevention and control of rice diseases.
