This is the first description of the complete genome sequence of a new bipartite begomovirus isolated from tomato (Solanum lycopersicum) in French Guiana, for which we propose the tentative name ¿tomato chlorotic mottle Guyane virus¿ (ToCMoGFV). DNA-A and -B nucleotide sequences of ToCMoGFV are only distantly related to known New World begomoviruses. They share the highest nucleotide sequence identity of 80 % with the Brazilian isolates of macroptilium yellow spot virus (MacYSV) and 73 % with soybean chlorotic spot virus (SBCSV). Phylogenetic analysis demonstrated that this novel virus belongs to a new lineage of New World bipartite begomoviruses. The discovery of this new virus confirms the high genetic diversity of begomoviruses in Latin America.
