Brief bio: I am interested in plant response to abiotic stresses, such as drought, salinity and abnormal temperatures. I started my research in plant sciences with Prof. Cheng-Bin Xiang in 2008. During my graduate study pursuing a Master’s degree, I focused my research on the roles of SULTR3, a chloroplast-specific sulfate transporter, in abiotic stress response. I obtained my doctoral degree in 2017 with the supervision of Dr. Jian-Kang Zhu. My dissertation was to elucidate the roles of chloroplast proteins in drought response in Arabidopsis. In the current paper, we show an important role of the chloroplast protein PPD5 in drought tolerance. We proposed that PPD5 acts as a negative regulator of ROS production in guard cells through the OST1-dependent pathway. This finding provides new insights into the regulatory mechanism underlying the induction of ROS in guard cells for drought response.
