Regulation of ADP-Glucose Pyrophosphorylase from Chlorella vulgaris.

abstract：:Programmed cell death (PCD) is essential for several aspects of plant life, including development and stress responses. Indeed, incompatible plant-pathogen interactions are well known to induce the hypersensitive response, a localized cell death. Mutational analyses have identified several key PCD components, and we r...
