Abstract 22 tRNA genes corresponding to 17 tRNA species were localized on the master circle of Petunia hybrida mitochondrial (mt) DNA. Genes for trnN, trnM, trnS-GGA, trnW and trnH are of the ‘chloroplast-like’ type and presumably originate from promiscuous chloroplast (cp) DNA sequences inserted into the petunia mitochondrial genome. A comparison of the mt tRNAs or tRNA genes population present in two monocotyledonous plants (wheat and maize) and two dicotyledonous plants (petunia and potato) show slight differences in the genetic origin of individual tRNAs. The organization of the petunia mt tRNA genes as well as the number of tRNA gene copies, compared to other plant species, is discussed.
