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
a proposal for a bean common mosaic subgroup of potyviruses.	in order to elucidate the taxonomic positions of bean common mosaic virus (bcmv) and blackeye cowpea mosaic virus (b1cmv), several strains of these viruses were compared on the basis of host ranges, antigenic properties established with antisera to virions and to n-terminal peptide domains of their coat proteins, and high performance liquid chromatographic peptide profiles. the comparison includes three strains of bcmv, viz. nl1, nl3 and ny15, four strains of b1cmv, viz. fla, ind, nr, and w, and ...	1992	1450765
serological and biological relationships among viruses in the bean common mosaic virus subgroup.	bean common mosaic virus (bcmv), blackeye cowpea mosaic virus (b1cmv), cowpea aphid-borne mosaic virus (cabmv), azuki bean mosaic virus (azmv), and peanut stripe virus (pstv) are five species of the genus potyvirus, family potyviridae which are seed-transmitted in beans or cowpeas. eighteen isolates of bcmv, five isolates of b1cmv, four isolates of cabmv, and one isolate each of azmv, and pstv were compared serologically using a panel of 13 monoclonal antibodies (mabs) raised against bcmv, b1cmv ...	1992	1450766
evidence that cowpea aphid-borne mosaic and blackeye cowpea mosaic viruses are two different potyviruses.	the immunoreactivity of a panel of polyclonal antibodies and monoclonal antibodies (mabs) raised against african isolates of potyviruses from cowpea and african yam bean was examined in elisas. a serological study including reference isolates followed by further characterization in differential hosts resulted in separation of the potyviruses into two distinct serogroups, one containing blackeye cowpea mosaic virus (blcmv) and the other containing cowpea aphid-borne mosaic virus (camv). using bio ...	1993	8445363
capsid protein properties of cowpea aphid-borne mosaic virus and blackeye cowpea mosaic virus confirm the existence of two major subgroups of aphid-transmitted, legume-infecting potyviruses.	a study of the capsid proteins of different legume-infecting potyviruses using specific monoclonal antibodies on immunoblots of crude extracts from infected plants revealed that cowpea aphid-borne mosaic virus (camv) and blackeye cowpea mosaic virus (bicmv) have coat protein m(r) values of 32k and 35k, respectively. immunoblot comparisons of bicmv, peanut stripe mosaic virus (pstv), bean common mosaic virus (bcmv) and azuki bean mosaic virus (azmv) revealed equal reactivity of their 35k coat pro ...	1994	7996147
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
transgenic plants expressing hc-pro show enhanced virus sensitivity while silencing of the transgene results in resistance.	nicotiana benthamiana plants were engineered to express sequences of the helper component-proteinase (hc-pro) of cowpea aphid-borne mosaic potyvirus (cabmv). the sensitivity of the transgenic plants to infection with parental and heterologous viruses was studied. the lines expressing hc-pro showed enhanced symptoms after infection with the parental cabmv isolate and also after infection with a heterologous potyvirus, potato virus y (pvy) and a comovirus, cowpea mosaic virus (cpmv). on the other ...	2002	12206307
subcellular location of the helper component-proteinase of cowpea aphid-borne mosaic virus.	the helper component-proteinase (hc-pro) of cowpea aphid-borne mosaic virus (cabmv) was expressed in escherichia coli and used to obtain hc-pro antiserum that was used as an analytical tool for hc-pro studies. the antiserum was used in immunofluorescence assays to study the subcellular location of hc-pro expressed with other viral proteins in cowpea protoplasts in a natural cabmv infection, or in protoplasts transfected with a transient expression construct expressing hc-pro separately from othe ...	2002	12416684
metagenomic-based screening and molecular characterization of cowpea-infecting viruses in burkina faso.	cowpea, (vigna unguiculata l. (walp)) is an annual tropical grain legume. often referred to as "poor man's meat", cowpea is one of the most important subsistence legumes cultivated in west africa due to the high protein content of its seeds. however, african cowpea production can be seriously constrained by viral diseases that reduce yields. while twelve cowpea-infecting viruses have been reported from africa, only three of these have so-far been reported from burkina faso. here we use a virion- ...	2016	27764211
