Programmed cell death (PCD) describes the death of plant and animal cells by processes under genetic control. In plants, processes associated with PCD have been identified in the hypersensitive response and tissue differentiation. The potential involvement of PCD in plant senescence and in response to altered temperatures and gas concentrations has implications for postharvest science. However, there is still little evidence for the full PCD or apoptotic pathway proceeding in such instances. Various features of PCD are involved, and study of these provides new information on nuclear changes, signalling and proteolytic metabolism under postharvest conditions. Results of the study on oat leaf senescence in the dark, where changes in chromatin condensation in nuclei taken from tissue at different stages were measured, are presented.
