Transcription profiling of Arabidopsis plants overexpressing MYB96 gene and myb96 knock-out mutant

ABSTRACT: The Arabidopsis MYB96 transcription factor plays a role in abscisic acid (ABA)-mediated drought response. To obtain clues as to how MYB96 promotes drought tolerance, we carried out microarray assays using the Affymetrix GeneChip. Experiment Design: Total RNAs were isolated from whole plants of two-week-old seedling of mutant plants overexpressing MYB96, MYB96-deficient mutants, and wild-types. Three independent biological replicates were performed for each sample.

ORGANISM(S): Arabidopsis thaliana

Drought stress activates several defense responses in plants, such as stomatal closure, maintenance of root water uptake, and synthesis of osmoprotectants. Accumulating evidence suggests that deposition of cuticular waxes is also associated with plant responses to cellular dehydration. Yet, how cuticular wax biosynthesis is regulated in response to drought is unknown. We have recently reported that an Arabidopsis thaliana abscisic acid (ABA)-responsive R2R3-type MYB transcription factor, MYB96,  ...[more]
