A begomovirus isolate (OY136A) collected
from okra plants showing upward leaf curling, vein clearing,
vein thickening and yellowing symptoms from Bangalore
rural district, Karnataka, India was characterized.
The sequence comparisons revealed that, this virus isolate
share highest nucleotide identity with isolates of Cotton
leaf curl Bangalore virus (CLCuBV) (AY705380)
(92.8 %) and Okra enation leaf curl virus (81.1–86.2 %).
This is well supported by phylogentic analysis showing,
close clustering of the virus isolate with CLCuBV. With
this data, based on the current taxonomic criteria for the
genus Begomovirus, the present virus isolate is classified as
a new strain of CLCuBV, for which CLCuBV-[India:
Bangalore: okra: 2006] additional descriptor is proposed.
The betasatellite (KC608158) associated with the virus is
having more than 95 % sequence similarity with the cotton
leaf curl betasatellites (CLCuB) available in the Gen-
Bank.The recombination analysis suggested, emergence of
this new strain of okra infecting begomovirus might have
been from the exchange of genetic material between
BYVMV and CLCuMuV. The virus was successfully
transmitted by whitefly and grafting. The host range of the
virus was shown to be very narrow and limited to two
species in the family Malvaceae, okra (Abelmoschus
esculentus) and hollyhock (Althaea rosea), and four in the
family Solanaceae.
