Tomato chlorosis virus (ToCV, genus Crinivirus, family Closteroviridae) is the causal
agent of a “yellow leaf disorder” of tomato (Solanum lycopersicum L.) that is present in
Florida at least since 1989 [6]. Nowadays, the presence of ToCV has been confirmed in
many countries of the Caribbean, the Far East, southern Africa, and northern and
southern sides of the Mediterranean Basin. In Spain, ToCV has been present in tomato
since at least 1997 [3] and also has been reported to infect sweet pepper (Capsicum
annuum L.) [1]. ToCV is a typical crinivirus with a bipartite genome (RNA1 and
RNA2) of single-stranded RNA of positive polarity. Recently, the complete nucleotide
sequence of RNA1 and RNA2 of a ToCV isolate from Florida [5], and of RNA2 of an
isolate from Spain (AT80/99) [2], have been reported. The sequence of the RNA1 of
isolate AT80/99 reported here completes the genomic sequence of an European isolate
of ToCV. |
