Molecular cloning, expression analysis and the study of the resistance to grape downy mildew of amine oxidase(AO) in Chinese Vitis amurensis‘Shuanghong'
【Objective】Grapevine downy mildew, caused by oomycete pathogen Plasmopara viticola, isone of the most destructive diseases affecting grapevines and economically causes great losses worldwide.Chinese wild Vitis amurensis‘Shuanghong'is characterized by good wine quality and cold tolerance andhas very strong resistance to downy mildew. In addition, it has been reported that amine oxidase(AO), anintercellular H2O2-producing enzyme in plant cells, also helps contribute to plant defense against downymildew. In or...
