- Abstract
Three begomoviruses were identified based on complete genome sequence from weeds in Jabalpur, Madhya Pradesh, Central India. Alternanthera yellow vein virus (AlYVV; 2745 bp) was identified in Alternanthera sessilis, Tobacco curly shoot virus (TbCSV; 2766 bp) in Sida acuta, and Cotton Leaf curl Bangalore virus (CLCuBaV; 2750 bp) in Malvastrum coromandelianum. A betasatellite DNA (1356 bp) was found associated with CLCuBaV, sharing sequence identity of 87-88% with those of other CLCuBaV isolates. TbCSV was detected in the food legumes soybean, black gram and pigeon pea, showing coinfection with Mungbean yellow mosaic India virus (MYMIV). Whitefly Bemisia tabaci, the vector of begomoviruses, harboured TbCSV and CLCuBaV at a high rate (10-60% and 5-30% respectively). The percentage of insects harbouring MYMIV was also extremely high (60-100), indicating that the whiteflies were viruliferous for multiple begomoviruses in this region. High population density of the whitefly and intensive cultivation of crop plants promote mixed infection of various begomoviruses in the fields of Central India.
