Brief bio: Throughout my postgraduate studies, I had the opportunity to work closely with Professor Shiping Wang and her research group. During this time, my research focused on elucidating the molecular mechanisms of sulfate inhibit the virulence of Xanthomonas oryzae pv. oryzae (Xoo) and Xanthomonas oryzae pv. oryzicola (Xoc) in rice. Additionally, I investigated the pathogenic mechanisms of TALEs, which are essential virulence factors in various plant pathogenic bacteria. The findings of my research were published in prestigious journals such as molecular plant, molecular plant pathology, and plant science, and have helped to advance our understanding of rice disease resistance.
I am currently working as a postdoctoral fellow in the lab of professor Meng Yuan at the national key laboratory of crop genetic improvement. Our study revealed that the bacterial pathogens Xoo and Xoc activate the expressions of miR156 and miR529, which in turn suppress the transcriptions of OsSPL7, OsSPL14, and OsSPL17. Down-regulated these OsSPLs could not efficiently activate the transcriptions of their downstream target genes OsAOS2 and OsNPR1, leading to decreased JA accumulation and weakened SA signaling pathway, respectively, which facilitate the infection of Xoo or Xoc. The revealed miR156/529-OsSPL7/14/17-OsAOS2/OsNPR1 regulatory network provides a potential strategy to improve rice resistance by suppressing miR156/529 expression or enhancing OsSPL7/14/17 expression.
