Description: English: Genome organization: sesbania mosaic virus (SeMV) is a single stranded RNA virus with genome size of 4147 nt. The 5′ end of the genome is covalently linked to VPg and the 3′ end lacks polyA tail. ORF 1 encodes movement protein and ORF 3 encodes the coat protein which is expressed through a subgenomic RNA (sgRNA). The ORF 2 codes for two polyproteins 2a and 2ab. The numbers indicate the position of start and stop codons in each of the ORFs. The polyprotein 2a contains N-terminal membrane anchor (MA)-protease-VPg-p10-p8 domains. The polyprotein 2ab contains N-terminal membrane anchor (MA)-protease-VPg-RdRp. The RdRp is expressed through a −1 ribosomal frame shifting mechanism. The numbers in the polyproteins 2a and 2ab indicate the cleavage site positions. Date: 15 February 2012. Source: https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0031190.
