Tomato is widely grown vegetable crop in
India and viral diseases are major constraint for its
production in the country. The chilli leaf curl virus
(ChiLCV) infecting chilli reported from the Indian subcontinent
is found associated with tomato enation leaf
curl disease in tomato growing areas of India. The leaf
samples showing enation leaf curl symptoms were collected
from tomato fields located in Sonipet (ten infected
and one healthy sample) of Haryana state and
Varanasi (five infected and one healthy sample) of
Uttar Pradesh state, India. Full length genome of
begomovirus and associated betasatellite were amplified,
cloned and sequenced. The Viral sequences represented
in the begomovirus clones showed 89–100 %
nucleotide sequence identity, suggesting that they represent
a single species. Comparisons to sequences available
in the databases showed nucleotide sequence identities
of 87.3–91.8 % for TC-Vns and 87.8–98.4 % for
TC287 and TC290, with Indian isolates of ChiLCV. The
betasatellite sequences obtained had 83.1–94.1 % identity
with tomato leaf curl Bangladesh betasatellite
(ToLCBDB). An analysis for recombinant origin of
genome and betasatellite showed major part of their
genome was likely to be originated by recombination
of begomo viruses infecting different host species
resulting in evolution of new recombinant virus. The
ChiLCV-tom reported in the current study is another
distinct strain of ChiLCV identified in tomato causing
enation leaf curl disease in India. The significance of
these findings is discussed.
