Phylogeny of Asian betasatellites associated with okra. Phylogenetic dendrogram based on an alignment of the complete nucleotide sequences of the betasatellites isolated from okra here with all sequences of Bhendi yellow vein betasatellite (BYVB), Okra leaf curl betasatellite (OLCuB) and Croton yellow vein mosaic betasatellite (CroYVMB) available in the databases and selected other betasatellite sequences. The additional betasatellites are Ageratum yellow vein betasatellite (AYVB), Cotton leaf curl Multan betasatellite (CLCuMB; of which there are two variants, the "Multan" and "Burewala" variants [24]), Cotton leaf curl Gezira betasatellite (CLCuGB), Malvastrum yellow vein betasatellite (MaYVB), Tobacco curly shoot betasatellite (TbCSV), Tobacco leaf curl betasatellite (TbLCV) and Tomato yellow leaf curl Thailand betasatellite (TYLCTHB). The virus isolate descriptors for additional sequences are as described in Briddon et al. [6] and the nucleotide sequence database accession numbers of all sequences are given, Numbers at nodes are percentage bootstrap confidence scores (1000 replicates). Malvaceous (Mal) and non-malvaceous (Non-mal) betasatellites, as defined by Briddon et al. [7], are indicated in the right-hand side.
