Transcription profiling of Arabidopsis wild type and abi1td mutant plants stressed by ozone or drought to better understand ABA signalling

ABSTRACT: Ozone at an elevated level is an important environmental stress factor that limits plant growth and development. To test how O3-induced ROS signalling interacts with the ABA pathway we present a global characterization of O3-responsive genes in the abi1td mutant. To understand better ABA signalling and the interactions between stress-response pathways we also performed a microarray analysis of drought-treated abi1td and WT plants. Since ABA signalling is well known to mediate defined responses based on the WT and different mutants analysis in drought stress conditions, the comparison of the O3 and drought stress response in abi1td enabled the identification of new processes depending on ABA-related pathways in O3-treated plants. Altogether, our findings indicate that ABI1 plays the role of
