High resolution temporal profiling of gene expression during Arabidopsis leaf development (senescence process)

ABSTRACT: Leaf senescence is an essential developmental process that involves altered regulation of thousands of genes and changes in many metabolic and signaling pathways resulting in massive physiological and structural changes in the leaf. The regulation of senescence is complex and although several senescence regulatory genes have been identified and characterized there is little information on how these individual regulators function globally in the control of the process. In this paper we use microarray analysis to obtain a high-resolution time course profile of gene expression during development of a single leaf over a three week period from just before full expansion to senescence. The multiple time points enable the use of highly informative clustering tools to reveal distinct time points a
