From: Yang cycle enzyme DEP1: its moonlighting functions in PSI and ROS production during leaf senescence

Fig. 7

The moonlighting protein MdDEP1 functions in two different directions to eventually regulate/control leaf senescence. On one direction, MdDEP1 activates the Yang’s cycle to promote ethylene production and signaling, which will weaken the function of photosystems and promote ROS production. On the other direction, MdDEP1 promote the MdY3IP1 dephosphorylation, whose degradation also inhibits the function of photosystems and promote ROS production. The weakened PSI/PSII functions and increased ROS production will lead to leaf senescence
