| 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 |
| strains of bean common mosaic virus consist of at least two distinct potyviruses. | bean common mosaic virus (bcmv) consists of a large number of pathotypes and strains which have largely been identified by their characteristic interactions with a selected number of differential bean cultivars. the relationships among these strains and other potyviruses that infect legumes are complex, with indications that bcmv, blackeye cowpea mosaic virus (blcmv) and azuki bean mosaic virus (azmv) may be strains of the one virus. using high performance liquid chromatographic peptide profiles ... | 1992 | 1450767 |
| coat protein properties suggest that azuki bean mosaic virus, blackeye cowpea mosaic virus, peanut stripe virus, and three isolates from soybean are all strains of the same potyvirus. | the interrelationship of a number of potyviruses infecting legumes has been investigated by comparing molecular properties of their coat proteins. comparison of the coat proteins by the techniques of amino acid analysis and page was inadequate to distinguish strains from distinct potyviruses. however, high-performance liquid chromatographic peptide profiles of tryptic digests of coat proteins of these legume-infecting potyviruses enabled such assignments to be made. these data indicate that amin ... | 1992 | 1500273 |
| 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 |
| sequence data to settle the taxonomic position of bean common mosaic virus and blackeye cowpea mosaic virus isolates. | the nucleotide sequences of the coat protein genes and 3' non-translated regions (3'-ntrs) of three isolates of bean common mosaic virus (nl1, nl3 and ny15) and one isolate of blackeye cowpea mosaic virus (w) were determined. comparison of these sequences revealed that the coat proteins of nl1, ny15 and w were identical in size (287 amino acids) and exhibited an overall sequence similarity (94 to 97%), and 84 to 98% in their n-terminal regions. furthermore, their 3'-ntrs were very similar in len ... | 1993 | 8409946 |
| 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 |
| sequences of the coat protein gene of five peanut stripe virus (pstv) strains from thailand and their evolutionary relationship with other bean common mosaic virus sequences. | the coat protein gene and part of the 3' non-coding region of five strains of peanut stripe virus (pstv) from thailand have been cloned and sequenced. phylogenetic comparisons of these strains, known as t1, t3, t5, t6 and t7, and related sequences showed that these strains are indeed strains of pstv. further, pstv strains appear to be related to each other according to their geographic origin. that is, the thai strains are more closely related to each other than they are to strains from the usa ... | 1998 | 9787652 |
| novel cytopathological structures induced by mixed infection of unrelated plant viruses. | abstract when two unrelated plant viruses infect a plant simultaneously, synergistic viral interactions often occur resulting in devastating diseases. this study was initiated to examine ultrastructural virus-virus interactions of mixed viral infections. mixed infections were induced using potyviruses and viruses from other plant virus families. novel ultrastructural paracrystalline arrays composed of co-infecting viruses, referred to as mixed virus particle aggregates (mvpas), were noted in the ... | 2004 | 18943827 |
