Relationships Among Australian and North American Isolates of the Bean Yellow Mosaic Potyvirus Subgroup

Inheritance of Resistance to the NL-8 Strain of Bean Common Mosaic Virus in Pisum sativum

“…Hence, there is indirect evidence that resistance to BCMV-NL8 does not depend on the genes for resistance to CYW or PSbMV-L. A further search among plant introductions could reveal different pea lines that possess specific genes for each of these potyviruses. All the potyviruses that infect pea have been reported to be directly or indirectly serologically related (Hollings and Brunt 1981), but they differ in many essential features, such as host range, symptoms incited in pea and other hosts, lack of cross protection, and RNA/ cDNA hybridization, which has revealed a low sequence homology among some of these viruses (Barnett et al 1987). Given that BCMV-NL8, CYW, PMV, and PSbMV are distinct entities, it is safe to assume that resistance to them is conferred by different genes.…”

Three strains of bean yellow mosaic virus: symptoms and accumulation in eight pea cultivars (Pisum sativum L.)

“…In legumes, BYMV is transmitted by several species of aphids in a non-persistent manner, and also experimentally in sap of infected plants (Bos 1970 a, Tapio 1970, Cockbain 1983 1984, Jayasena and Randles 1985, Bays and Demski 1986, Winter and Nienhaus 1989, Provvidenti 1991. Many strains of BYMV have been reported which may be distinguished by host range, aphid transmission, serology or RNA sequence heterology (Bos 1970 a, Jones and Diachun 1977, Reddick and Barnett 1983, Schmidt and Zobywalski 1984, Herrera and Sepulveda 1986, Barnett et al 1987, Scott et al 1989, Hopps and Mclaughlin 1990. The pea strain of BYMV, formerly considered a distinct virus from the bean strain of BYMV and called pea mosaic virus (PMV), causes bright yellow mosaic symptoms, whereas the bean strain of BYMV causes green mosaic symptoms in pea leaves (Bos 1970b, Tapio 1970).…”

Relatedness of the Nucleotide Sequence of the 3′-Terminal Region of Clover Yellow Vein Potyvirus RNA to Bean Yellow Mosaic Potyvirus RNA

“…Host ranges and symptoms produced by these viruses are similar to (but distinct from) each other, and all are related serologically to some extent. Several at tempts have been made to clarify the rela tionships of the viruses using host range and symptomatology, serology, amino acid com position data, and molecular hybridization of genome RN As [1][2][3][4]. Jones and Diachun [2] treated the cluster as a single virus consisting of three subtypes based on symptomatology and agar gel diffusion serology.…”

“…This comprised BYMV, BYMV-P, and BYMV-SP. The BYMV cluster was further defined by Bar nett et al [1] as the bean yellow mosaic poty vi rus subgroup. The relationships of 17 isolates in the subgroup were investigated by molecu lar hybridization and by direct enzymelinked immunosorbent assay.…”
