Abstract

Association of a new begomovirus with leaf crumple disease of Jatropha curcas was identified based on sequence analysis of cloned ~2.7-kb viral DNA genomes from three representative samples amplified by RCA using phi-29 DNA polymerase. Sequence analysis of these isolates SKJ1 (KM066975), SKJ2 (KM189818) and SKJ3 (KM189819)—showed the presence of a monopartite begomovirus-like genome of 2,735 to 2,738 nucleotides containing seven ORFs: V3, V2 and V1 in virion sense and C3, C2, C1 and C4 in the complementary sense. Pairwise alignment showed 99 % nucleotide sequence similarity to each other and less than 81 % identity to other begomoviruses reported worldwide. Based on begomovirus species demarcation criteria for a new species (sequence identity <89 %), the begomovirus isolates were identified as the members of a new Begomovirus species and provisionally designated as Jatropha leaf crumple India virus (JLCrIV).
