Transcription profiling of Arabidopsis dor mutant and wild type plants in response to drought stress.

ABSTRACT: ATH1 GeneChip was used for gene expression analysis of wild-type plants and dor mutant under drought treatment (both the wild-type and dor plants were grown under normal watering conditions for 24 days and then stressed by completely depriving of irrigation for 10 days). Two biological repeat experiments were conducted and the raw data was analyzed applying Affymetrix GCOS software. Experiment Overall Design: ATH1 GeneChip was used for gene expression analysis of wild-type plants and dor mutant under drought treatment (both the wild-type and dor plants were grown under normal watering conditions for 24 days and then stressed by completely depriving of irrigation for 10 days).

Guard cells, which form stoma in leaf epidermis, sense and integrate environmental signals to modulate stomatal aperture in response to diverse conditions. Under drought stress, plants synthesize abscisic acid (ABA), which in turn induces a rapid closing of stoma, to prevent water loss by transpiration. However, many aspects of the molecular mechanism for ABA-mediated stomatal closure are still not understood. Here, we report a novel negative regulator of guard cell ABA signaling, DOR, in Arabid  ...[more]
