Abstract excerpt
BACKGROUND: Caspases are a family of aspartate-specific cysteine proteases that play an essential role in initiating and executing programmed cell death (PCD) in metazoans. Caspase-like activities have been shown to be required for the initiation of PCD in plants, but the genes encoding those activities have not been identified. VPEgamma, a cysteine protease, is induced during senescence, a form of PCD in plants,...
