Programmed cell death (PCD) plays important roles in regulating plant development and stress responses, and the reactive oxygen species (ROS) acts as the key regulator in PCD process. However, the underlying mechanism remains to be addressed. Recently, the Jiayang Li’s group from Institute of Genetics & Developmental Biology, Chinese Academy of Sciences has made great breakthroughs in the mechanism of PCD regulated by ROS. The group demonstrated that malate shuttling from the chloroplast to mitochondrion triggers ROS production and subsequent PCD in Arabidopsis. The study provides novel results for understanding the mechanism of PCD regulation.
