Microarray technology has enabled scientists to investigate plant structure and function from a molecular perspective, identifying key regulatory elements in environmental responses. New information obtained from global gene expression profiling in plants has provided a new dimension on agriculture, offering a unique opportunity to maximize agricultural yield using genetic manipulation and awareness. Fujita et al (2005) used the Agilent Arabidopsis 2 Oligo Microarray to establish the function of the abscisic acid-responsive Element Binding Protein 1 (AREB1) as a transcription activator of novel ABA-responsive element (ABRE)-dependent abscisic acid signaling, enhancing drought stress tolerance in Arabidopsis. Combining differential expression analyses using microarrays and RNA gel blots, with information on stress inducibility and cis promoter elements, the group identified two groups of candidate target genes of AREB1. This study provides greater understanding of important underlying AREB1 mechanisms and functions in a novel ABRE-dependent ABA signaling pathway in drought stress.

AREB1 is postulated to mainly regulate the expression of stress-responsive genes via ABRE sequences in vegetative tissues. Genes downstream of AREB1 have been mapped and likely enhance drought stress tolerance and increase fundamental cellular activities under stress conditions.
