| Description | All cells are born in more or less the same way, and die in more or less different ways. Leaf cells, with which this chapter is primarily concerned, are typical of plant cells in their origins and ultimate fates. A leaf cell faces the prospect of one of at least five distinct modes of death. It may be programmed to die during normal development as part of processes that create complex organ shapes and specialized cell types. For instance, the pinnate (fan-like) leaves of palms arise by death of strips of cells (lorae) that divide the lamina into long thin leaflets (Kaplan et al., 1982). Environmental deviations beyond the adaptive limits of the cell usually result in necrotic cell death (Pennell and Lamb, 1997). One form of disease resistance in plants is the hypersensitive response, a type of programmed cell death (PCD; Beers, 1997). The tissue may be consumed by a predator, an extremely common fate for the foliage of many species, and one that triggers cell death processes with far-reaching ecological implications (Chapter 22). The cell may undergo senescence, a component of normal development intimately associated with, but significantly different from, autolytic and/or pathological cell death. This chapter is concerned mainly with senescence. Book Name: Programmed Cell Death in Animals and Plants |
