This is the first description of the complete genome sequence of a new monopartite begomovirus isolated from tomato with symptoms of tomato (yellow) leaf curl disease collected in the Seychelles. The DNA-A-like nucleotide sequences share the highest nucleotide sequence identity (84%) with tomato leaf curl Anjouan virus (ToLCAnjV) from the Comoros islands. Phylogenetic analysis confirmed its recombinant nature and its relationship to Old World monopartite and bipartite begomoviruses. This discovery of a new member of a species confirms the high genetic diversity of begomoviruses in the south-western Indian Ocean islands.
