Programmed Cell Death in Plant-pathogen Interactions.
Plants cope with pathogen attacks by using mechanisms of resistance that rely both on preformed protective defenses and on inducible defenses. The latter are the most well studied, and progress is being made in determining which induced responses are responsible for limiting pathogen growth. Many plant-pathogen interactions are accompanied by plant cell death. Recent evidence suggests that this...
متن کاملVacuolar processing enzyme in plant programmed cell death
Vacuolar processing enzyme (VPE) is a cysteine proteinase originally identified as the proteinase responsible for the maturation and activation of vacuolar proteins in plants, and it is known to be an ortholog of animal asparaginyl endopeptidase (AEP/VPE/legumain). VPE has been shown to exhibit enzymatic properties similar to that of caspase 1, which is a cysteine protease that mediates the pro...
متن کاملProgrammed cell death remodels lace plant leaf shape during development.
Programmed cell death (PCD) functions in the developmental remodeling of leaf shape in higher plants, a process analogous to digit formation in the vertebrate limb. In this study, we provide a cytological characterization of the time course of events as PCD remodels young expanding leaves of the lace plant. Tonoplast rupture is the first PCD event in this system, indicated by alterations in cyt...
متن کاملMetacaspase-dependent programmed cell death is essential for plant embryogenesis
In plants, as in animals, programmed cell death (PCD) is a key process responsible for the elimination of unneeded structures and for overall shape remodeling during development [1]; however, the molecular mechanisms remain poorly understood. Despite the absence of canonical caspases in plants, dying plant cells show an increased proteolytic caspase-like activity [2]. Moreover, the cell death c...
متن کاملHydrogen peroxide as a signal controlling plant programmed cell death
Hydrogen peroxide (H2O2) has established itself as a key player in stress and programmed cell death responses, but little is known about the signaling pathways leading from H2O2 to programmed cell death in plants. Recently, identification of key regulatory mutants and near-full genome coverage microarray analysis of H2O2-induced cell death have begun to unravel the complexity of the H2O2 networ...
