Abstract

A begomovirus disease complex associated with Vernonia cinerea showing yellow vein symptoms was studied. The full-length genomic DNA was comprised of 2739 nucleotides (nt) and contained the typical genome structure of begomoviruses. Comparison analysis showed that it shared the highest (78.9%) nucleotide sequence identity with recently characterized Vernonia yellow vein virus (VeYVV) from India. For associated satellites, betasatellite showed the highest nucleotide sequence identity (52.1%) with Vernonia yellow vein virus betasatellite (VeYVVB) and alphasatellite shared the highest sequence identity (70.7%) with Gossypium mustelinium symptomless alphasatellite (GMusSLA). It is a member of a distinct species with cognate alpha- and betasatellites for which the name Vernonia yellow vein Fujian virus (VeYVFjV) is proposed.
