Detection of a conserved arrangement of three tRNA genes in the sunflower mitochondrial genome. Identification, mapping and expression of trnC-trnN-trnY genes

Biochem Mol Biol Int. 1994 Apr;32(6):1161-72.

Abstract

The genes coding for tRNA-Cys (trnC), tRNA-Asn (trnN) and tRNA-Tyr (trnY) have been sequenced in a region of about 3.0 kb of the sunflower mitochondrial DNA. The trnC and trnY are genuine mitochondrial genes, while the trnN gene has a chloroplast origin. Despite their heterologous origin the three genes are transcribed. Their arrangement is the first detected in a highly conserved form in a specific group of advanced dicots.
