Abstract

The nucleotide sequence of turnip crinkle virus (TCV) genomic RNA has been determined from cDNA clones representing most of the genome. Segments were confirmed using dideoxynucleotide sequencing directly from viral RNA, and the 3′ terminal sequence was confirmed by chemical sequencing of end-labeled genomic RNA. Three open reading frames (ORFs) have been identified by examination of the deduced amino acid sequences and by comparison with the ORFs found in the genome of carnation mottle virus. ORF 1 initiates near the 5′ terminus of the genome and is punctuated by an amber termination codon. Translation of ORF 1 would yield a 28-kDa protein and an 88-kDa read-through product. The read-through domain possesses amino acid sequence similarities with putative viral RNA polymerases. ORFs 2 and 3 encode products of 38 (coat protein) and 8 kDa, respectively, which are expressed from subgenomic mRNAs. The organization of the TCV genome suggests that TCV is closely related to carnation mottle virus and distinct from members classified in other small RNA virus groups, such as the tombus- and sobemoviruses.
