Involvement of ROS1 in gene expression of imazethapyr-treated Arabidopsis thaliana

Purpose: To determine candidate genes involved in the increased susceptibility of ros1 plants to imazethapyr. Results: Our study reveled that that imazethapyr up-regulated genes related to chemical stimulus, secondary metabolism, stress condition, flavonoid biosynthesis and epigenetic processes. We identified 31 candidate genes as putative involved in herbicide detoxification, some of this genes are under epigenetic regulation of ROS1. Overall design: Genome-wide transcriptome analysis of genes expressed at 48 hours after imazethapyr treatment contrasting with control condition, in wild type (WT) and REPRESSOR OF SILENCING 1 (ros1) plants
