- Abstract
The complete genome sequence of a Capsicum chlorosis virus from China (CaCV-Hainan) was determined. The tripartite genome of CaCV-Hainan consists of small (S), medium (M), and large (L) RNAs of 3629, 4859, and 8912 nucleotides (nt), respectively. The S and M RNAs contain intergenic regions (IGRs) of 1348 and 462 nt, respectively. Strikingly, sequence comparisons among CaCV isolates revealed that the S RNA IGR of CaCV-Hainan derived from the CaCV-Qld-3432 Australia isolate through deletion of two stretches of 25- and 325-nt sequences within the S RNA IGR of CaCV-Qld-3432. Moreover, the S RNA IGR of CaCV-Hainan was inserted with two stretches of 10- and 20-nt sequences of an unknown origin. The S RNA IGR of CaCV-Ph from Taiwan and CaCV-NRA from Thailand also derived from the CaCV-Qld-3432 through deletion of 218-nt sequences. Our findings provide valuable new insight into the structural variations and evolutionary origin of CaCV IGRs.
