Transcriptome analysis of Arabidopsis thaliana G protein subunit mutants in response to abscisic acid (ABA)

ABSTRACT: Heterotrimeric G proteins mediate crucial and diverse signaling pathways in eukaryotes. To gain insights into the regulatory modes of the G protein and the co-regulatory modes of the G protein and the stress hormone abscisic acid (ABA), we generated and analyzed gene expression in G protein subunit single and double mutants of the model plant Arabidopsis thaliana. Through a Boolean modeling approach, our analysis reveals novel modes of heterotrimeric G protein action. Keywords: transcriptome analysis; G protein subunit mutants; abscisic acid (ABA) Microarray data were generated from four genotypes (wild type, gpa1-4 mutant, agb1-2 mutant, agb1-2 gpa1-4 double mutant) with or without ABA treatment. Arabidopsis plants were grown in growth chambers with an 8 hr light/16hr dark. Three hundr
