AB Southern tomato virus (STV) from genus Amalgavirus (Family Amalgaviridae) is a persistent virus infecting tomato cropsworldwide. Information on genetic diversity and evolutionary mechanisms for plant persistent viruses are very scarce incomparison with plant acute viruses. In this work, the putative coat protein gene of worldwide STV isolates was analyzedshowing very low nucleotide diversity (< 0.0100). Phylogenetic analysis separated STV isolates into two clades, but nocorrelation was found between genetic and geographic distances. Also, no recombination events among STV isolates weredetected. Comparison of synonymous and nonsynonymous substitutions indicated negative selection at the amino acid level.
