| Research Abstract |
Plant mitochondrial genes that had been transferred to the nuclei were searched in the database. Numerous duplications were identified in Chinese cabbage. In radish, syntenic regions were dispersed throughout the genome.
During the course of the analysis, the gene, showing homology to a ribosomal protein gene in the upstream region and to an amino acid biosynthetic gene in the downstrean region, has been found in the database. There are five paralogs in the genome, three of which are pseudogenes. It is suggested that the gene was created by a recombination via an intron. The gene products seem to be localized to mitochondria and chloroplasts by using GFP. In addition, a case of gene fusion between a ribosomal protein gene and a sugar metabolic enzyme gene has been identified.
