Yellow vein mosaic disease of okra is a whitefly
transmitted begomovirus causing heavy economic loss in
different parts of India. The okra isolate (OY131) of this
virus from a bhendi plant [(Abelmoschus esculentus L.)
Moench] showing yellow vein mosaic, vein twisting,
reduced leaves, and a bushy appearance in the Palem region,
New Delhi, India, was characterized in the present study. The
complete DNA-A and DNA-B sequences have been determined
and are comprised of 2,746 and 2,703 nucleotides,
respectively. The betasatellite (DNA-b) component was
absent in the sample. The genome organization was typically
of biparite begomoviruses, which were characterized earlier.
Comparison of DNA-A component with other known
begomoviruses suggest that this virus, being only distantly
related (85.9% similarity with its nearest relative,
BYVMV) to other known begomoviruses, is a new species.
We have tentatively assigned the genome to a novel
geminivirus species Bhendi yellow vein mosaic Delhi virus
[BYVDV - IN (India: Delhi: okra)]. DNA-B showed highest
sequence identity (87.8% identical) to that of a ToLCNDV
(AY158080). The phylogenetic analysis of the present isolate
is distinct from all other viruses; however clusters with
ToLCNDV group infect different crops. The recombination
analysis revealed that this isolate has sequences originated
from ToLCNDV. This is the first known bhendi yellow vein
mosaic disease associated bipartite begomovirus from India.
