Comparative Potyvirus Host Range, Serology, and Coat Protein Peptide Profiles of White Lupin Mosaic Virus

A potyvirus isolated from white lupin (Lupinus albus) plants with severe mosaic symptoms was purified; compared with other selected potyviruses in terms of host range, serology, and coat protein peptide profiles; and found to be distinct. Accordingly, it has been assigned a new name, white lupin mosaic virus (WLMV). In reciprocal enzyme-linked immunosorbent assays with polyclonal antisera, WLMV behaved similarly to the Scott isolate of bean yellow mosaic virus (BYMV) and was distinguishable from the PMV-1 isolate of pea mosaic virus and the Pratt isolate of clover yellow vein virus (CYVV) (...)
