- Abstract
We investigated the molecular characteristics of an Argentinean isolate of alfalfa leaf curl virus (ALCV-Arg), a virus of the genus <italic>Capulavirus</italic> in the family <italic>Geminiviridae</italic> that was isolated from alfalfa plants showing dwarfism. The genome was found to be 2,750 nucleotides in length. In pairwise comparisons, this ALCV isolate shared 83.2% to 92.6% sequence identity with European ALCV isolates. Sequence comparisons and phylogenetic analysis showed that this isolate combines features of strains A and B of ALCV. Recombination analysis showed that ALCV-Arg is a recombinant isolate that was generated by intraspecific recombination between ALCV strains A and B. The results of this study not only show that ALCV-Arg is unique because it combines features of strains A and B but also show that ALCV naturally infects this forage crop on the American continent.
