Identification of two methionine transfer RNA genes in the maize mitochondrial genome.
Two methionine transfer RNA (tRNA) genes were identified in the maize mitochondrial genome by nucleotide sequence analysis. One tRNA gene was similar in nucleotide sequence and secondary structure to the initiator methionine tRNA genes of eubacteria and higher plant chloroplast genomes. This tRNA gene also had extensive nucleotide homology (99%) with an initiator methionine tRNA gene described for the wheat mitochondrial genome. The other methionine tRNA gene sequence was distinct and more closely resembled an elongator methionine tRNA.
