WebNov 26, 2013 · Chlorophyll (Chl) breakdown is the hallmark of senescence because of its impact on the color of senescing organs: loss of green Chls unmasks yellow carotenoids and highlights the synthesis of red anthocyans. Why do plants degrade Chls? WebTaken together, pathogen-induced lysoPCs enhance pathogen susceptibility accompanied by ROS and ethylene biosynthesis, resulting in chlorophyll degradation and cell death. Expression of PR genes (PR1-a, PR-3, and PR-4b) and LOX3 was strongly induced in lysoPC 18:1-treated leaves, indicating the involvement of lysoPC 18:1 in the defense …
