Tomato leaf curl Kunene virus: a novel tomato-infecting monopartite begomovirus from Namibia.

: 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 northwestern Namibia, which we provisionally name "tomato leaf curl Kunene virus". The DNA-A-like nucleotide sequence shares the highest nucleotide sequence identity (82.8%) with tobacco leaf curl Zimbabwe virus (ToLCZWV). Phylogenetic analysis confirmed its affiliation with Old World monopartite begomoviruses. The discovery of a new begomovirus in a vegetable plant in Namibia highlights the importance of maintaining epidemiological surveillance in southern Africa.
