“…Pea seed-borne mosaic virus (PSbMV) is one of many potyviruses that are seed transmitted in legumes and that are of major economic importance (Khetarpal and Maury, 1987). Typical for this group of viruses, PSbMV has a (+) sense RNA genome of 9.9 kb (Johansen et al, 1991) that is encapsidated within a flexuous filamentous particle.…”

Pea seed-borne mosaic virus (PSbMV), a seed-transmitted virus in pea and other legumes, invades pea embryos early in development. This process is controlled by maternal genes and, in a cultivar that shows no seed transmission, is prevented through the action of multiple host genes segregating as quantitative trait loci. These genes control the ability of PSbMV to spread into and/or multiply in the nonvascular testa tissues, thereby preventing the virus from crossing the boundary between the maternal and progeny tissues. lmmunocytochemical and in situ hybridization studies suggested that the virus uses the embryonic suspensor as the route for the direct invasion of the embryo. The programmed degeneration of the suspensor during embryo development may provide a transient window for embryo invasion by the virus and could explain the inverse relationship between the age of the mother plant for virus infection and the extent of virus seed transmission.

“…Here, we report the development of an immunogold labelling procedure using antisera to PSbMV particles and pinwheel inclusion bodies, and its application to the study of the cytology of PSbMV infection. An important property of PSbMV is its high rate of seed transmission in some pea cultivars (Musil, 1966;Inouye, 1967;Stevenson and Hagedorn, 1969;Khetarpal and Maury, 1987). Our Lin and Langenberg (1983).…”

“…The potyvirus PSbMV mainly infects P. sativum and, to some extent, other legumes (16). Historically, PSbMV isolates have been grouped as pathotypes P-1, P-2, and P-4, depending on their infection profile on a selection of P. sativum lines (1).…”

Pea seed-borne mosaic potyvirus (PSbMV) isolates are divided into pathotypes P-1, P-2, and P-4 according to their infection profile on a panel of Pisum sativum lines. P. sativum PI 269818 is resistant to P-1 and P-2 isolates and is susceptible to P-4 isolates. Resistance to P-1 is inherited as a single recessive gene, denoted sbm-1, and the pathogenicity determinant has previously been mapped to the virus-coded protein VPg. In the cultivar Bonneville, a second recessive gene, sbm-2, confers specific resistance to P-2. By exchanging cistrons between a P-2 and a P-4 isolate, the P3-6k1 cistron was identified as the PSbMV host-specific pathogenicity determinant on Bonneville. Exchange of P3-6k1 did not affect infection on PI 269818, and infection of Bonneville was not altered by substitution of the VPg cistron, indicating that P3-6k1 and VPg are independent determinants of pathotype-specific infectivity. On PI 269818 the pathogenicity determinant of both P-1 and P-2 mapped to the N terminus of VPg. This suggests that VPg from the P-1 and P-2 isolates are functionally similar on this host and that resistance to P-1 and P-2 in PI 269818 may operate by the same mechanism. Identification of VPg-sbm-1 and P3-6k1-sbm-2 as independent pairs of genetic interactors between PSbMV and P. sativum provides a simple explanation of the three known pathotypes of PSbMV. Furthermore, analysis of ␤-glucuronidase-tagged P-2 virus indicated that sbm-2 resistance affected an early step in infection, implying that the P3-6k1 region plays a critical role in potyvirus replication or cell-to-cell movement.
