摘要: The complete sequence of a potyvirus from maize in Zhejiang Province was determined. The RNA was 9596 nucleotides long, excluding the 3'-poly (A) tail, and there was a single long open reading frame (ORF) of 9192 nts encoding a 346.1 ku polyprotein. The polyprotein had substantial amino and sequence homology with those encoded by the RNAs of a Chinese isolate of sorghum mosaic virus (SrMV-C) and a Bulgarian isolate of maize dwarf mosaic virus, but it was most closely related to sugarcane mosaic virus (SCMV) isolates, for which only partial sequences have been published. According to the published criteria for distinguishing polyviruses, the sequence reported here is clearly a strain of SCMV, but it also showed a surprisingly high amino acid homology with SrMV-C in the HC-Pro, P3 and CI proteins.
