A new variant of Croton yellow vein mosaic virus naturally infecting wild sunflower in India.

ABSTRACT: During 2015-2016, wild sunflower (Verbesina encelioides) was observed with bright yellow vein mosaic symptims in Noida, Uttar Pradesh, India. The initial analysis by PCR with a pair of coat protein based primers revealed the association of a begomovirus. Further, the virus was identified by rolling circle amplification and cloning of the complete genome. The DNA-A (2671 nucleotides, MH359168) with the genome organisation typical of the Old World begomovirus shared 98% sequence identity with that of Croton yellow vein mosaic virus (CYVMV) reported from India. The betasatellite (MH359169) associated with the disease shared 92% sequence identity with papaya leaf curl betasatellite (KY825245). The results showed that the wild sunflower is a new alternate host of CYVMV. The study also re
