摘　　要：烟草病毒是影响烟草生产的重要病原,常造成复杂且严重的病害.研究利用宏病毒组测序和分子检测技术,分析云南省保山市隆阳区2022—2023年烟草病毒的多样性及危害特征.结果表明:2022年各地块烟草病毒危害情况轻于2023年.危害烟草的烟草病毒主要有6种,分别为烟草花叶病毒(Tobacco Mosaic Virus,TMV)、马铃薯Y病毒(Potato Virus Y,PVY)、辣椒脉斑驳病毒(Chilli Veinal Mottle Virus,ChiVMV)、番茄斑萎病毒(Tomato Spotted Wilt Virus,TSWV)、黄瓜花叶病毒(Cucumber Mosaic Virus,CMV)和烟草曲叶病毒(Tobacco Leaf Curl Virus,TLCV).TMV为主要优势病毒,PVY和ChiVMV危害显著上升,且部分病毒株系呈现显著的地域分化特性.研究结果为云南省保山市烟草病毒病流行机制的深入解析和科学防控提供了重要依据.Tobacco viruses are important pathogens that significantly impact tobacco production,often causing complex and severe diseases.This study utilized metagenomic sequencing and molecular detection techniques to analyze the diversity and harm characteristics of tobacco viruses in Longyang District,Baoshan City,Yunnan Province,from 2022 to 2023.The results showed that the virus damage to tobacco in 2022 was less severe compared to 2023.Six tobacco viruses were identified as the main pathogens:Tobacco Mosaic Virus(TMV),Potato Virus Y(PVY),Chilli Veinal Mottle Virus(ChiVMV),Tomato Spotted Wilt Virus(TSWV),Cucumber Mosaic Virus(CMV),and Tobacco Leaf Curl Virus(TLCV).TMV was the dominant virus,while the damage by PVY and ChiVMV increased significantly.Furthermore,some virus strains exhibited distinct characteristics of regional differentiation.The findings provide important insights into the viral epidemic mechanisms in tobacco plants in Baoshan,Yunnan,and offer valuable data for effective control strategies.
