The species,distribution,and dynamic state of whitefly-transmitted geminiviruses in Guangdong
In order to monitor occurrence and diffusion dynamics of whitefly-transmitted geminiviruses(WTGs)in Guangdong province,the situation of diseases induced by WTGs in the whole province was extensively investigated during 2003-2021.Results showed that the diseases induced by WTGs have occurred on 24 species of plants including tomato,squash,sweet potato etc.in 14 cities including Guangzhou,Zhanjiang,Huizhou etc.of Guangdong province.The occurrence and harm of WTGs-induced disease such as tomato yellow leaf curl disease on tomato production were particularly severe,which were spread over the main tomato production areas of the province.21 species of WTGs were identified on disease samples collected from 14 cities.Tomato yellow leaf curl Guangdong virus(TYLCGdV),tomato leaf curl Guangdong virus(ToLCGdV),Allamanda leaf curl virus(A11LCV),Pouzolzia mosaic Guangdong virus(PouMGDV),Lycianthes yellow mosaic virus(LyYMV)were new species of WTGs.At the same time,we found that the species of WTGs infected different hosts were different,and the species of WTGs infected the same crop were dynamically changing.This study confirmed the wide distribution,variety,and serious harm of WTGs in Guangdong province,which provided scientific basis for the prevention and control of diseases induced by WTGs in Guangdong province.
