The genome organization of lucerne transient streak and turnip rosette sobemoviruses revisited

The genome organization of lucerne transient streak and turnip rosette sobemoviruses revisited Unlike other sobemoviruses, lucerne transient streak viru s (LTSV) and turnip rosette virus (TRoV) have been reported to contain two successive ORF1s (denoted as ORF1a and ORF1b) instead of a single ORF1. Also, their next ORF (ORF2a/2a2b) has been mapped to a region ca. 200 nucleotides downstream from that of other sobemoviruses, leading to the lack of transmembrane segments at the N-termini of P2a/2a2b. In the current study, we resequenced this region for TRoV and LTSV. The hypothetical beginning of ORF1b was mapped as the beginning of ORF2a/2a2b for both TRoV and LTSV.

Abstract

Unlike other sobemoviruses, lucerne transient streak viru s (LTSV) and turnip rosette virus (TRoV) have been reported to contain two successive ORF1s (denoted as ORF1a and ORF1b) instead of a single ORF1. Also, their next ORF (ORF2a/2a2b) has been mapped to a region ca. 200 nucleotides downstream from that of other sobemoviruses, leading to the lack of transmembrane segments at the N-termini of P2a/2a2b. In the current study, we resequenced this region for TRoV and LTSV. The hypothetical beginning of ORF1b was mapped as the beginning of ORF2a/2a2b for both TRoV and LTSV. Computional analysis revealed transmembrane segments at the N-termini of the TRoV and LTSV polyproteins.
