Abstract
The genome of the higher plant mitochondria has been decided in Arabidopsis, sugar beet and rice plant by the present. The genotypic composition is not completely same between plant species, and there is a gene which is lacking to each other. This fact is indicating that the gene transfer to the nucleus is the developing on higher plant mitochondria at present. And, the transfer of some gene from the plastid is also observed. Thus, genome analysis of mitochondria are necessary, when transfer of gene and evolution of 3 kinds of genomes of plant cell are examined. In addition, it waits for the experimental analysis in in vitro of RNA editing mechanism and self-splicing mechanism of the group II intron.
We decided genome base sequence of the tobacco mitochondria. At present, the genome/genetic analysis are advanced in order to clarify many above-mentioned and unsolved problems.
