“…A number of isolates or strains of PSbMV have been characterized using differential pea lines with a major emphasis on symptomatology. 14 For pea breeding purposes, isolates of PSbMV should, instead, be classified on the basis of genes able to control them (pathotype groups). A pathotype is denned as an entity of a given virus that is controlled by a specific genetic factor in a given plant species or family.…”

In Pisum sativum, two independently inherited single recessive genes were found to confer resistance to the same pathotype of pea seed-borne mosaic virus from lentil (PSbMV-L1). The gene sbm-2, present in the domestic cuttivar Bonneville, was determined to be closely linked to mo, which conditions resistance to bean yellow mosaic virus and watermelon mosaic virus 2 and is known to be located In Pisum linkage group 2. The second gene, sbm-3, was found in PI 347492, a bean yellow mosaic virus-susceptible line from India, and apparently is located in a different linkage group. Both genes, independently of each other, confer resistance to PSbMV-L1, but whether they are repetitive entities remains to be determined. Pea seed-borne mosaic virus (PSbMV) was characterized by Musil in Czechoslovakia and by Inouye in Japan. 1518 In 1968, this virus was found in the United States, 917-22 and since then, its presence has been ascertained in several other countries. 13 In searching for sources of resistance to PSbMV, Stevenson and Hagedorn, Baggett and Hampton, and Hampton and Braverman screened hundreds of accessions of Pisum sativum L. with the standard strain (PSbMV-ST) and found resistant germ plasm among foreign introductions. 312-23 Hagedorn and Gritton determined that, in PI 193586 and PI 193835 accessions from Ethiopia, resistance was conferred by a single recessive gene (sftm). 8 Recently, Goodell and Hampton and Ashby et al reported that PSbMV isolates from lentils (PSbMV-L) and from New Zealand peas (PSbMV-NZ) were unable to infect pea cultivars possessing mo, the gene for resistance to bean yellow mosaic virus (BYMV). 26-24 Alconero et al demonstrated that resistance to PSbMV-Pl and PSbMV-P4 (from pea), and to PSbMV-Ll (from lentil), was pathotype specific. 1 Consequently, it appears that in P. sativum, there are distinct genetic entities for resistance to PSbMV, with each factor capable of controlling only a specific pathotype of the virus. Alone or in combination, these resistance factors were found in a number of plant introductions (Pis), mostly from. India and Ethiopia. 1 '"

“…In comparisons using P. sativum differentials, PSbMV-Pam usually produced milder symptoms than PSbMV-L and isolate E21O, especially in failing to produce whole plant necrosis in plants of host group I. In this, it resembles the Dutch isolate E224 (Hampton et a!. 1981).…”

“…Comparison of PSbMV-Pam with PSbMV isolated from BYMV -immune peas using an international set of pea differentials An isolate ofPSbMV was obtained from an infected line of the BYMV-immune cultivar 'Small Sieve Freezer'. This isolate (designated PSbMV-SSF) and PSbMV-Pam were inoculated to representatives of each group of the Pisum sativum differentials described by Hampton et al (1981). Symptoms were recorded three weeks after inoculation and symptomless plants were indexed using Chenopodium amarantic%r Coste and Reyne.…”

A strain of pea seed-borne mosaic virus isolated from the field pea cultivar 'Pamaro' and designated PSbMV-Pam was unable to infect pea cultivars homozygous for the mo gene which confers resistance to bean yellow mosaic virus. PSbMV-Pam was efficiently transmitted by Acyrthosiphon pisum (Harris) and Myzus persicae (Sulzer), but poorly by Aulacorthum solani (Kaltenbach). Using an international set of Pisum sativum L. differential hosts, PSbMV-Pam was shown to resemble both a Dutch isolate and a lentil strain of PSbMV from the United States, but, in most instances, produced milder symptoms. PSbMV-Pam could be distinguished from an isolate from the pea cultivar 'Small Sieve Freezer' by means of direct ELISA but not by indirect assay.

“…Through international comparison, pea leafroll mosaic virus was found to be one of the isolates of pea seed-borne mosaic virus which was described during the late 1960's more or less simultaneously with varying names in different parts of the world [41]. Cross-protection tests and electron microscopy were not of much help for distinguishing between the different potyviruses.…”

Summary. At first potyviruses were easily distinguished by biological and serological properties because only a few were known and information on their host ranges was limited. The first evidence of serological cross reaction between two of these viruses was reported in 1951 and was further corroborated for three obviously distinct members of the group in 1960. In 1968 attention was drawn to the fact that some legume and non-legume potyviruses have much wider host ranges than previously known and that within the potyvirus group there is as much biological variation within viruses and overlap between viruses as there is in serology. The concept of continuity within the group was soon supported by others and became known as the "continuum hypothesis." Results with highly sensitive serological methods using polyclonal antisera were conflicting, and nucleic acid hybridization techniques did not unambiguously discriminate between potyviruses.Recent results, obtained with antibodies directed toward epitopes located in the N -termini of the coat proteins of potyviruses, suggest that there are ways to more definitely group strains of one potyvirus and distinguish them from other potyviruses. However, there are exceptions to this rule, as in the case of bean yellow mosaic virus and clover yellow vein virus which are clearly distinct in host range, inclusion bodies, and migration velocity of coat protein, but which still react with antibodies to the N-terminal epitopes of one virus. So the question remains of whether coat-protein properties, especially the serological reactivity of N-termini, which do not alter overall virus integrity when lost, sufficiently represent the genome of a pathogenic virus entity as a single criterion for classification.
