Leaf senescence--not just a 'wear and tear' phenomenon.
A recent, genome-wide study shows that the transcriptional program underlying leaf senescence is active and complex, reflecting the activation of more than 2,000 genes in Arabidopsis, with gene products involved in a broad spectrum of regulatory, biochemical and cellular events.
