Alfalfa (Medicago sativa L.) is a commonly grown forage crop in Oregon and California harvested on 350,000 and 480,000 acres, respectively, in 2023 (USDA-NASS 2023). Forage alfalfa is grown as a perennial crop for about four years in the same field and each season, the crop is cut 3-4 times for hay production.

Bean common mosaic virus (BCMV) is causing economically important diseases in leguminous crops worldwide. In this study, BCMV isolates from country bean (CB; ), yard-long bean (YLB; ), and rajma bean (RB; ) collected from Bangladesh, Nepal, and Cambodia were characterized. Samples that tested positive for BCMV in serological assays were subjected to high-throughput sequencing to generate near-full-length genome sequences.

A novel totivirus, named "birch toti-like virus" (BTLV), was discovered in European white birch (Betula pendula) plants. The genome of BTLV is 4,967 nucleotides long and contains two overlapping open reading frames (ORFs) coding for the capsid protein (CP) and an RNA-dependent RNA-polymerase (RdRP). The encoded CP and RdRP proteins shared 46.

An investigation of viruses circulating in populations of field and laboratory potato/tomato psyllids () was conducted using high-throughput sequencing (HTS) technology and conventional RT-PCR. Three new viruses were discovered: one from the family and two from the family . A tymo-like virus sequence represented a nearly complete 6843 nt genome of a virus named Bactericera cockerelli tymo-like virus (BcTLV) that spanned five open reading frames (ORFs) which encoded RNA-dependent RNA polymerase (RdRP), helicase, protease, methyltransferase, and a capsid protein.
