Abstract
The complete genomes of a monopartite begomovirus
(genus Begomovirus, family Geminiviridae) and
an associated betasatellite found infecting Vernonia
amygdalina Delile (family Compositae) in Uganda were
cloned and sequenced. Begomoviruses isolated from two
samples showed the highest nucleotide sequence identity
(73.1% and 73.2%) to an isolate of the monopartite begomovirus
tomato leaf curl Vietnam virus, and betasatellites
from the same samples exhibited the highest nucleotide
sequence identity (67.1% and 68.2%) to vernonia yellow
vein Fujian betasatellite. Following the current taxonomic
criteria for begomovirus species demarcation, the isolates
sequenced here represent a novel begomovirus species.
Based on symptoms observed in the field, we propose the
name vernonia crinkle virus (VeCrV) for this novel begomovirus
and vernonia crinkle betasatellite (VeCrB) for the
associated betasatellite. This is the first report of a
monopartite begomovirus-betasatellite complex from
Uganda.
