Abstract

The complete genome sequence of a distinct variant of tomato yellow leaf curl virus-Israel (TYLCV-IL) and the DNA-A sequence of a new strain of tomato severe leaf curl virus (ToSLCV) isolated in San Luis Potosi, Mexico, are described and analyzed. The TYLCV-IL[MX:SLP:11] variant differs from all TYLCV-IL isolates described so far by a unique 42-nt duplicated sequence comprising a part of the conserved stem-loop element of the virion-strand replication origin and adjacent regulatory sequences. TYLCV-IL[MX:SLP:11] was associated with tomato chino La Paz virus (ToChLPV-B[MX:SLP:11]) in a Solanum pimpinellifolium plant, and with pepper huasteco yellow vein virus (PHYVV-[MX:SLP:11]) and ToSLCV-GT[MX:SLP:11] in a Solanum lycopersicum plant. In addition, a distinct ToSLCV exhibiting low sequence identity (<89 %) to other ToSLCV isolates from Mexico was found in a tomato plant collected in the same field. Sequence analysis of this new ToSLCV strain indicates that it is a recombinant of close relatives of ToSLCV-GT[MX:SLP:11] and ToChLPV-B[MX:SLP:11] found in mixed infections with TYLCV-IL[MX:SLP:11].
