国家知识产权局近日公开一件由云南省烟草农业科学研究院申请的发明专利:一种鉴定烟草PVY抗性的分子标记。该发明属于分子生物学领域,是一种鉴定烟草PVY抗性的分子标记。该发明涉及扩增该分子标记的引物、该分子标记和引物在烟草抗病资源筛选和抗病育种辅助选择中的用途。该发明的分子标记将基因组DNA序列与烟草PVY抗性基因联系起来,有利于烟草分子标记育种辅助选择体系的建
State Intellectual Property Office recently announced an application by the Yunnan Provincial Academy of Tobacco Agricultural Science and invention patent application: a tobacco PVY identification of molecular markers of resistance. This invention belongs to the field of molecular biology and is a molecular marker for identifying the resistance of tobacco to PVY. The invention relates to the use of the primer for amplifying the molecular marker, the molecular marker and the primer for screening tobacco resistance resources and supporting disease-resistant breeding. The molecular marker of the invention relates the genomic DNA sequence to the tobacco PVY resistance gene and is favorable for the construction of a tobacco molecular marker breeding aid selection system
