Patterns of Genetic Diversity among Alphasatellites Infecting Gossypium Species.

ABSTRACT: Alphasatellites are small single-stranded circular DNA molecules associated with geminiviruses and nanoviruses. In this study, a meta-analysis of known alphasatellites isolated from the genus Gossypium (cotton) over the last two decades was performed. The phylogenetic and pairwise sequence identity analysis suggested that cotton-infecting begomoviruses were associated with at least 12 different alphasatellites globally. Three out of twelve alphasatellite were associated with cotton leaf curl geminiviruses but were not isolated from cotton plants. The cotton leaf curl Multan alphasatellite, which was initially isolated from cotton, has now been reported in several plant species, including monocot plants such as sugarcane. Our recombination analysis suggested that four alphasatellites
