Phylogenetic analysis of the reverse transcriptase (rt) domain sequences of Bagy-2 and related Ty3/gypsy retrotransposons. The neighbor-joining tree was inferred from Kimura estimates of sequence distance. Numbers at the nodes are the bootstrap values of 500 replicates. Some of the sequences were obtained from GenBank (see Fig.5 for accessions); the others, determined by us (accession nos.AJ295085–AJ295139), are in capital letters. Genomic sequences are labeled with the suffix -G, cDNA sequences from leaves, -L; cDNA sequences from cultured cells, -C.
