Abstract: | Summary The relationship of the Morocco isolate of watermelon mosaic virus (WMV) to WMV 2, soybean mosaic virus (a virus closely related to WMV 2) and the W strain of papaya ringspot virus (PRSV-W), formerly WMV 1, was examined by comparing tryptic peptide profiles using high performance liquid chromatography. The profiles indicated that the coat protein sequence of WMV-Morocco differed substantially from those of the other potyviruses. This conclusion was supported by sequence data from five tryptic peptides from the coat protein of WMV-Morocco, which showed only 61–68% identity to equivalent sequences in PRSV-W, WMV 2 and zucchini yellow mosaic, another potyvirus infecting cucurbits. Based on the above data, and on known correlations between coat protein sequence similarities and potyvirus relationship, it is concluded that WMV-Morocco should be regarded as a distinct potyvirus. |
