【 摘 要 】

An initiator methionine transfer RNA (tRNA_f ^Met) gene has been identified by sequence analysis of a cloned SalI restriction fragment of wheat mitochondrial DNA. The 3′-end of this gene, which does not encode the CCA terminus of the mature tRNA, is separated by only one basepair from the 5′-end of the 18 S ribosomal RNA gene, suggesting that the two genes are part of the same transcriptional unit. The wheat mitochondrial tRNA_f ^Met sequence, the first from plant mitochondria, displays strong structural affinity with eubacterial/chloroplast tRNA_f ^Met sequences.
