近日,中国烟草组织实施的烟草基因组计划重大专项率先实现对烟草抗黑胫病、抗黄瓜花叶病毒病(CMV)和抗赤星病等重要抗病基因的精确定位。这是我国在烟草基因组研究方面取得的又一标志性成果。烟草重要性状基因精确定位是我国烟草基因组计划重大专项的主体工作之一。经两年的攻关,将烟草抗黑胫病基因(Ph)锁定在20号连锁群上的两个特定分子标记之间 Recently, the major project of Tobacco Genome Project implemented by China Tobacco took the lead in realizing the accurate positioning of important disease-resistance genes such as tobacco anti-shank disease, cucumber mosaic virus disease (CMV) and resistance to brown spot disease. This is yet another landmark achievement our country has made in the study of the tobacco genome. Precise positioning of tobacco important trait genes is one of the main tasks of the major project of tobacco genome project in China. After two years of research, the tobacco anti-shank gene (Ph) was locked between two specific molecular markers on linkage group 20
