The nucleotide sequences of tRNA(Asn) (GUU) and tRNA(Tyr) (GUA) genes from tomato mitochondria and their flanking regions have been determined. The tomato mitochondrial tRNA(Asn) gene is located 2.1 kb downstream from the tRNA(Cys) gene reported previously (Izuchi and Sugita 1989) and shows a nearly complete identity with the corresponding chloroplast gene. The tRNA(Tyr) gene, which shows only 73% homology with the corresponding chloroplast gene, has to be considered a "native" mitochondrial tRNA gene and is 535 bp from the "chloroplast-like" tRNA(Asn) gene on the same strand. Northern hybridization analysis revealed that the three tRNA genes are transcribed in tomato mitochondria. Southern hybridization analysis of tomato, sugar beet. rice and wheat mitochondrial DNAs, with oligonucleotide probes for mitochondrial or chloroplast tRNA genes, demonstrated that the mitochondrial tRNA(Cys) gene found in tomato is present in dicot plants but not in monocots. On the other hand, a chloroplast-like tRNA(Cys) gene exists in monocot plants.
