The Zinc-Finger Protein Zat12 Plays a Central Role in Reactive Oxygen and Abiotic Stress Signaling in Arabidopsis

摘要: Plant acclimation to environmental stress is controlled by a complex network of regulatory genes that compose distinct stress-response regulons. In contrast many signaling and are specific, the zinc-finger protein Zat12 responds large number biotic abiotic stresses. thought be involved in cold oxidative Arabidopsis (Arabidopsis thaliana); however, its mode action regulation largely unknown. Using fusion between promoter reporter gene luciferase, we demonstrate expression activated at transcriptional level during different stresses response wound-induced systemic signal. gain- loss-of-function lines, assign function for oxidative, osmotic, salinity, high light, heat Transcriptional profiling Zat12-overexpressing plants wild-type subjected H2O2 revealed constitutive results enhanced oxidative- light transcripts. Under specific growth conditions, may therefore regulate collection transcripts stress. Our suggest plays central role reactive oxygen Arabidopsis.
