METACASPASE9 modulates autophagy to confine cell death to the target cells during <i>Arabidopsis</i> vascular xylem differentiation

Abstract excerpt

We uncovered that the level of autophagy in plant cells undergoing programmed cell death determines the fate of the surrounding cells. Our approach consisted of using Arabidopsis thaliana cell cultures capable of differentiating into two different cell types: vascular tracheary elements (TEs) that undergo programmed cell death (PCD) and protoplast autolysis, and parenchymatic non-TEs that remain alive. The TE...
