Chloroplast degradation: one organelle, multiple degradation pathways

Degradation of chloroplasts is a hallmark of both natural and stress-induced plant senescence. Autophagy and senescence-associated vacuoles are two established cellular pathways for chloroplast degradation. Recently, a third independent pathway for chloroplast degradation was reported. Here we will discuss this new discovery in relation to the other known pathways. Degradation of chloroplasts is a hallmark of both natural and stress-induced...
