摘要：
A new strain of Capsicum chlorosis virus (CaCV) from peanut (Arachis hypogaea L.) in China, designated CaCV-CP, was characterized. CaCV-CP causes yellow spots and necrosis on the leaves of affected peanut plants. Of 31 plant species inoculated mechanically, 24 were susceptible to this strain. Quasi-spherical virions were present in ultrathin section of diseased leaves. The complete sequence of S RNA of CaCV-CP consisted of 3399 nucleotides (nts). The NSs and N genes of the virus contained 1320 nts and 828 nts, respectively; these two open reading frames were in an ambisense arrangement. The N gene of CaCV-CP shared 84.7-86.4% and 92.4-93.1% identity with that of CaCV strains from Thailand and Australia at nt and amino acid levels, respectively (the GenBank accession number of the sequence reported in this study is DQ355974).
