The putative causal agent of the disease, a negative-sense RNA virus and new member of the genus Emaravirus, is identified and characterized and diversity studies demonstrated that the virus has low diversity between isolates as they share nucleotide identities ranging from 97 to 99%.
Potyvirus genome-linked protein (VPg) determines pea seed-borne mosaic virus pathotype-specific virulence in Pisum sativum.

Lack of viral coat protein or RNA in P-1 transfected sBM-1/sbm-1 protoplasts suggests that sbm-1 resistance is occurring at the cellular level and that inhibition of cell-to-cell virus movement is not the operating form of resistance.
Molecular characterization and population structure of blackberry vein banding associated virus, new Ampelovirus associated with yellow vein disease.
Suppression of potyvirus infection by coexpressed closterovirus protein.
Results indicated that BYV L-Pro specifically interfered with TEV systemic transport and accumulation in a host-dependent manner and suggested a potential utility of closterovirus L- pro as an inhibitor of potyvirus infection.
Evidence of sympatric speciation of elderberry carlaviruses.

Five new carlaviruses infecting elderberry were characterized and tentatively named as elderberry virus A-E (ElVA-ElVE), indicating that speciation may be sympatric with all viruses having emerged in elderberry.
Identification and Detection of a Virus Associated with Strawberry Pallidosis Disease.
Alignments of the major coat protein show that the virus isolated from strawberry plants positive for pallidosis is most closely related to Cucumber yellows virus and Cucurbit yellow stunt disorder virus, members of the Crinivirus genus.
2020 taxonomic update for phylum Negarnaviricota (Riboviria: Orthornavirae), including the large orders Bunyavirales and Mononegavirales.
The updated taxonomy of Negarnaviricota is presented, as now accepted by the ICTV, after the phylum was amended and emended in March 2020.
Cowpea viruses in Senegal, West Africa: identification, distribution, seed transmission and sources of genetic resistance.
Viral diseases of cowpea in Senegal were surveyed during the rauny seasons of 1990 and 1991 and detected in four recognized viruses, all of which are seed-transmissible in cowpeA.
New viruses found in fig exhibiting mosaic symptoms
During the molecular characterization of the Fig mosaic virus, two new closteroviruses and a new badnavirus affecting the tree used in studies are discovered.
DEVELOPMENT OF RESISTANCE TO RASPBERRY BUSHY DWARF VIRUS IN 'MEEKER' RED RASPBERRY
Of 197 transgenic lines planted in replicated blocks in the field under extreme disease pressure, five lines remained free of RBDV after four years, and fruit evaluations of these five lines showed that they contained the five anthocyanins at the same relative concentrations as were present in wild type ‘Meeker’ fruit.
