Genetic Variability and Molecular Evolution of Tomato Mosaic Virus Populations in Three Northern China Provinces.

ABSTRACT: RNA viruses tend to mutate during transmission and host infection, which is critical to viral adaptation and evolution. Tomato mosaic virus (ToMV) is a member of the genus Tobamovirus (family Virgaviridae) and an economically important virus with detrimental effects on tomatoes worldwide. Although the ToMV gene sequences have been completed in China, their genetic diversity and population structure remain unclear. We collected 425 tomato samples from tomato-growing areas in three northern Chinese provinces 2016. Reverse transcription PCR results showed that the average incidence of the virus in the field samples was 67.15%, and ToMV was detected in all test areas. The analysis of ToMV single nucleotide polymorphisms in China showed that ToMV was evolutionarily conserved, and
