Nucleotide sequence of the 3'-terminal region of citrus tatter leaf virus RNA

The 3'-terminal sequence of citrus tatter leaf virus lily isolate (CTLV-L) was determined from cloned cDNA. The sequence contains two open reading frames (ORFs). ORF1 encodes a protein that contains consensus sequences associated with the RNA-dependent RNA polymerase. ORF2, which is in a different reading frame within ORF1, can encode a 36 kD protein, putatively identified as a movement protein. CTLV-L coat protein (CP) was found to be located in the C-terminal region of the polyprotein encoded by ORF1. Evolutionary relationships and classification of capilloviruses is discussed.
