The aims of this research are• To identify the genes mediating Plasmopara viticola resistance in the loci Rpv12 and Rpv10 and understand their transcript structure and function• To deduce gene-linked molecular markers for efficient Marker-assisted selection in grapevine breeding• To investigate the host-pathogen interaction on histochemical level in resistant grapevine carriers of Rpv12 and Rpv10 (Production of reactive oxygen species at the infection site, Hypersensitive reaction)• To contribute to our understanding of the resistance mechanisms behind Rpv12 and Rpv10 at the level of molecular physiology in the host-pathogen interaction and gene regulation

本研究的目的是·鉴定Rpv12和Rpv10基因座上介导稻瘟病菌抗性的基因并了解其转录本的结构和功能·为葡萄育种提供有效的标记辅助选择的基因连锁分子标记·研究携带Rpv12和Rpv10抗性葡萄的寄主与病原菌在组织化学水平上的相互作用(侵染部位产生活性氧，超敏反应)·有助于从分子生理水平上了解Rpv12和Rpv10在寄主-病原相互作用和基因调控方面的抗性机制
