Genome of a known but distinct begomovirus associated with a novel satellite molecule infecting a new host bitter gourd ().

(KY860899), (KY860898) and (KY848691) were found to be associated with leaf curl disease in (bitter gourd). The complete nucleotide sequence of showed 82% identity with (KM244719), whereas was 96% identical to (KP868764) and illustrated 81% similarity with (JQ041697). Phylogenetic and RDP analysis revealed the proximity of these begomoviruses with other monopartite begomoviruses and alphasatellites already reported from India. As per the threshold criteria laid down by International Committee on Taxonomy of Viruses for species demarcation in begomoviruses and satellite molecules, the identified virus isolates, and are proposed as new species. To the best of our knowledge, this is the first ever account of mixed infection of begomoviruses in , a vegetable crop commonly cultivated throughout India.
