| cowpea aphid borne mosaic virus-morocco and south african passiflora virus are strains of the same potyvirus. | high performance liquid chromatography (hplc) profiles of tryptic peptides and partial amino acid sequence analysis have been employed to establish the taxonomic status of the moroccan isolate of cowpea aphid-borne mosaic virus (cabmv). some previous reports have suggested cabmv to be very closely related to blackeye cowpea mosaic virus (b1cmv) while other reports have concluded that this relationship is distant. in this report a tryptic digest of the coat protein of cabmv-morocco was compared w ... | 1994 | 8002788 |
| a mosaic disease of senna hirsuta induced by a potyvirus in nigeria. | a virus inducing mosaic and severe leaf malformation, isolated from senna hirsuta in nigeria, was studied. the virus had a rather narrow host range, infecting a few species in caesalpinaceae, chenopodiaceae and fabaceae families. the virus was widespread in southern nigeria with prevalence ranging from 74% to 86.4% in some locations. it was transmitted mechanically and in a non-persistent manner by myzuspersicae, aphis craccivora and a. spiraecola. there was no evidence of transmission by seeds. ... | 2001 | 11719985 |
| inheritance of resistance to potyviruses in phaseolus vulgaris l. iv. inheritance, linkage relations, and environmental effects on systemic resistance to four potyviruses. | we have examined the genetics of systemic resistance in phaseolus vulgaris to azuki bean mosaic virus (azmv) and cowpea aphid-borne mosaic virus (cabmv) and the relationship of this resistance to a phenotypically similar resistance to watermelon mosaic virus (wmv) and soybean mosaic virus (smv). in p. vulgaris cv 'great northern 1140' (gn1140), resistance to smv and wmv has been attributed to the genes smv and wmv, respectively, which have been shown to segregate as a unit. systemic resistance t ... | 1996 | 24166169 |
| inheritance of resistance to potato y viruses in phaseolus vulgaris l : 1. two independent genes for resistance to watermelon mosaic virus-2. | resistance to watermelon mosaic virus-2 in phaseolus vulgaris l. is conferred by two distinct dominant alleles at independent loci. based on segregation data one locus is designated wmv, the other, hsw. the dominant allele wmv from cv. great northern 1140 prevents systemic spread of the virus but viral replication occurs in inoculated tissue. in contrast, hsw confers both local and systemic resistance to wmv-2 below 30c. at higher temperatures, plants that carry this allele in the absence of mod ... | 1987 | 24240215 |
