Complete nucleotide sequence of a new virus, peach chlorotic leaf spot virus, isolated from flat peach in China

Contigs with sequence homologies to apple chlorotic leaf spot virus (ACLSV) were identified by high-throughput sequencing analysis in three peach samples. Complete genomic sequences of RP19-1 and RP19-2 of the virus consisted of 7,466 and 7,465 nucleotides (nts), respectively, excluding the poly (A) tails. They shared the highest identity with Ta Tao 5, but lower than 70% of sequence similarity with other ACLSV isolates. Furthermore, phylogenetic analysis revealed that these two isolates clustered with Ta Tao 5, which is distinct from other ACLSV isolates. According to the criteria for species demarcation within the genus Trichovirus , these two isolates as well as Ta Tao 5 should be recognized as a new virus species, tentatively named “ Peach chlorotic leaf spot virus ”.
