The stress hormone abscisic acid is crucial to survival in Arabidopsis upon drought stress. Key abscisic acid signal transduction proteins have YFP fusions and have had complexes purified for analyzing signal transduction partners using mass spectrometry. This research will lead to identification of new candidate proteins that function in early abscisic acid signal transduction. The identified proteins will further be compared to guard cell specific genomic scale analyses of gene expression that have been completed using Affymetrix Genechips. Gene knockout experiments will verify the functions of the mass spectrometrically identified proteins.
