TaATG8 Is Involved in the Response to Abiotic Stresses and Powdery Mildew in Arabidopsis

ATG8 is a key gene in the process of autophagy. The expression of ATG8 affects many intracellular progresses. Here we report that the amino acid sequence of AtATG8 and TaATG8 protein share a high similarity of 84.03%, we found that TaATG8 involved in the abiotic stresses, such as drought, salt stress and nutrient deficiency. Moreover, TaATG8 plays an important role in the process of Arabidopsis defending against biotic stress caused by the infection of powdery mildew through HR. Hydrogen peroxide acts as an important metabolic product and signaling molecule in the process of TaATG8 resisting to powdery mildew.
