A new strain of tomato severe leaf curl virus and a unique variant of tomato yellow leaf curl virus from Mexico

A new strain of tomato severe leaf curl virus and a unique variant of tomato yellow leaf curl... 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). http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Archives of Virology Springer Journals

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).
