Programmed Cell Death in Plants

quence tag sequences, obtained from cDNA libraries con-structed with RNA from cells at different stages of the life cycle of the fungus (28) and from cells under heat or cadmium stress (5) The microarrays were used to study the global changes in transcript levels in cells isolated at different times after induc-tion of germination in nutrient

Seasonal relationships between cyst germination and

quence of mass cyst germination Instead, the blooms can be initiated by a very small number of vegetative cells The cysts generally germinate after the bloom of the vegetative population, but not before The tempo-ral discrepancy between the peak of vegetative popu-lations and the peak of germination rates has also been

cycle enzymes and terminal oxidases to provide adequate amounts of ATP to support metabolism for several hours after imbibition (Ehrenshaft and Brambl, 1990; Attucci et al , 1991) During germination of embryos, there appear to be two distinct patterns of mitochondrial development These pat-terns, which are particularly obvious in cotyledons

during seed development and germination Taiji Kawakatsu1,2,3, Joseph R Nery1,2, Rosa Castanon1,2 and Joseph R Ecker1,2,4* Abstract Background: Unlike animals, plants can pause their life cycle as dormant seeds In both plants and animals, DNA methylation is involved in the regulation of gene expression and genome integrity In animals
