Tomato chlorotic mottle Guyane virus: A novel tomato-infecting bipartite begomovirus from French Guiana

Lett J.M., De Bruyn A., Hoareau M., Ouattara A., Claverie S., Dalmon A., Laplace D., Lefeuvre P., Hostachy B.. 2015. Archives of Virology, 160 (11) : p. 2887-2890.

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. (Résumé d'auteur)
