The complete nucleotide sequence and genome organization of a peach virus isolate from a naturally infected peach tree showing typical peach wart-like symptoms on the fruit surface was determined and compared to sequences of members of the family Betaflexiviridae. The genome consists of 7,987 nucleotides, excluding the poly-A tail, and has four open reading frames (ORFs). Analysis of the whole genome and putative proteins encoded by each ORF revealed greatest sequence similarity to a cherry isolate of cherry mottle leaf virus (CMLV). The two isolates have similar genome organizations and share 88 and 93 % homology in their corresponding products of the replicase and coat protein genes, respectively. CMLV has been reported from several Prunus spp. and may be associated with peach wart-like disease symptoms on peach fruit.Electronic supplementary materialThe online version of this article (doi:10.1007/s00705-013-1698-3) contains supplementary material, which is available to authorized users.
