TL;DR: In this article, an analysis of changes in global gene expression patterns during developmental leaf senescence in Arabidopsis has identified more than 800 genes that show a reproducible increase in transcript abundance.

TL;DR: The current understanding of the mechanisms by which plants control senescence and the processes that are involved is presented.

TL;DR: Experiments show, for the first time, that the salicylic acid (SA)-signalling pathway has a role in the control of gene expression during developmental senescence, and suggest that a combination of signalling factors is required for the optimum expression of many genes duringsenescence.

TL;DR: It is found that storage at cooler temperatures delayed the symptoms of senescence at both the biochemical and gene expression levels, and indicated that, in the initial stages of postharvest senescences, an orderly dismantling of the cellular constituents occurs, using the available lipid as an energy source.

TL;DR: The analysis of knockout insertion mutants in two different senescence-enhanced genes, one encodes a heat shock transcription factor and the other a zinc finger protein is described, indicating that expression of these genes duringsenescence has a protective role to maintain viability during this essential developmental process.
