Genomic characterization of pea enation mosaic virus-2 from the Pacific Northwestern USA

Pea enation mosaic virus (PEMV) infects several legume crops, including chickpea (Cicer arietinum), faba bean (Vicia faba), lentil (Lens culinaris) and pea (Pisum sativum). The virus caused yield losses of food legumes in the Pacific Northwestern US during 1983, 1987 and 1990 . Our recent surveys of pea and alfalfa fields in the states of Washington and Idaho, USA, have shown the prevalence of PEMV on pea. PEMV consists of a large (RNA-1 or PEMV-1) and a small (RNA-2 or PEMV-2) single-stranded positive-sense RNA, which are encapsidated separately into distinct isometric particles .
PEMV-2 is one of the seven distinct virus species in the genus Umbravirus. The other species of this genus are Carrot mottle virus (CMoV), Carrot mottle mimic virus (CMoMV), Groundnut rosette virus (GRV), Lettuce speckles mottle virus (LSMV), Tobacco mottle virus (TMoV) and Tobacco bushy top virus (TBTV) . Members of this group lack the coat protein (CP) gene in their genomes and...
