The nucleotide sequences of nine genes corresponding to tRNA(Ser)4 or tRNA(Ser)7 of Drosophila melanogaster were determined. Eight of the genes compose the major tRNA(Ser)4,7 cluster at 12DE on the X chromosome, while the other is from 23E on the left arm of chromosome 2. Among the eight X-linked genes, five different, interrelated, classes of sequence were found. Four of the eight genes correspond to tRNA(Ser)4 and tRNA(Ser)7 (which are 96% homologous), two appear to result from single crossovers between tRNA(Ser)4 and tRNA(Ser)7 genes, one is an apparent double crossover product, and the last differs from a tRNA(Ser)4 gene by a single C to T transition at position 50. The single autosomal gene corresponds to tRNA(Ser)7. Comparison of a pair of genes corresponding to tRNA(Ser)4 from D. melanogaster and Drosophila simulans showed that, while gene flanking sequences may diverge considerably by accumulation of point changes, gene sequences are maintained intact. Our data indicate that recombination occurs between non-allelic tRNA(Ser) genes, and suggest that at least some recombinational events may be intergenic conversions.
