Host Range Determination of Pepper Vein Yellows Virus in Guizhou Province
摘要
Abstract
To elucidate the host range of pepper vein yellows virus(PeVYV),twenty-one plant species from seven distinct families were inoculated with virus-carrying cotton aphids.After a period of twenty days,the infection status of the tested plants was assessed through symptom observation and reverse transcription polymerase chain reaction(RT-PCR)detection.The results indicated that plant species from four families(Solanaceae,Compositae,Cucurbitaceae,and Brassicaceae)were successfully inoculated with PeVYV and exhibited symptoms including yellowing,mosaic patterns,and mottling.Conversely,plants from the Amaranthaceae and Chenopodiaceae families did not display the typical symptoms associated with viral infection;however,the presence of the virus was confirmed via RT-PCR.No viral symptoms were observed in plants from the Fabaceae family,and the virus was not detected within this family.Thus,PeVYV is capable of infecting host plants such as pepper,tobacco,tomato,eggplant,petunia,cabbage,radish,watermelon,leaf lettuce,and stem lettuce.These findings suggest that PeVYV possesses a broad host range and has a significant potential for epidemic development.关键词
