日前,从中国农业科学院烟草研究所获悉,烟草马铃薯Y病毒病抗性基因挖掘研究取得新进展,揭示了烟草响应马铃薯Y病毒的生物学过程,锁定了6个重要抗性基因。烟草马铃薯Y病毒病是由马铃薯Y病毒(Potato virus Y,PVY)引起的一种烟草系统性侵染病害,该病毒是马铃薯Y病毒科(Potyviridae)马铃薯Y病毒属(Potyvirus)的典型成员,在生产中对烟草品质造成严重影响。近年来, Recently, the Chinese Academy of Agricultural Sciences Institute of Tobacco was informed that the tobacco potato Y virus resistance gene mining new progress has been made to reveal the tobacco response to potato Y virus biological processes, locked six important resistance genes. Tobacco potato virus Y disease is a systemic tobacco infestation caused by the Potato virus Y (PVY), a typical member of the potato genus Potyvirus of the family Potyviridae. Production has a serious impact on the quality of tobacco. In recent years,
