Beet soil-borne mosaic virus (BSBMV) is a member of the Benyvirus genus together with Beet necrotic yellow vein virus (BNYVV), both transmitted by Polymyxa betae. BSBMV is widely distributed only in the United States and, up to date, it has not been reported in others countries. It was first identified in Texas as a sugar beet virus morphologically similar but serologically distinct to BNYVV. Sequence analysis of BSBMV RNAs showed similar genomic organization to that of BNYVV but sufficient molecular differences to distinct BSMBV and BNYVV in two different species. The described BSBMV genome consists of four RNAs capped at the 5’end and 3’ polyadenylated. RNA-1, and 2 are, respectively, 6,683 and 4,615 nucleotides in length and contain putative ORFs similar to which identified on BNYVV RNA-1 and 2. The 1,720 nt BSBMV RNA-3 has a 29 kDa ORF that share 23% amino acid sequence identity with the 25 kDa ORF of BNYVV RNA3.

Abstract
Beet soil-borne mosaic virus (BSBMV) is a member of the Benyvirus genus together with Beet necrotic yellow vein virus (BNYVV), both transmitted by Polymyxa betae. BSBMV is widely distributed only in the United States and, up to date, it has not been reported in others countries. It was first identified in Texas as a sugar beet virus morphologically similar but serologically distinct to BNYVV. Sequence analysis of BSBMV RNAs showed similar genomic organization to that of BNYVV but sufficient molecular differences to distinct BSMBV and BNYVV in two different species. The described BSBMV genome consists of four RNAs capped at the 5’end and 3’ polyadenylated. RNA-1, and 2 are, respectively, 6,683 and 4,615 nucleotides in length and contain putative ORFs similar to which identified on BNYVV RNA-1 and 2. The 1,720 nt BSBMV RNA-3 has a 29 kDa ORF that share 23% amino acid sequence identity with the 25 kDa ORF of BNYVV RNA3.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
