Abstract

The nucleotide sequence of a 27,588-bp region of rice mitochondrial DNA was
determined. This sequence contains putative genes that encode initiator
methionine tRNA (trnfM), subunits III (nad3) and IV (nad4) of the NADH
dehydrogenase complex, and ribosomal proteins S3 (rps3), S12 (rps12) and L16
(rpl16). An open reading frame that contains sequences homologous to parts of
rps2 and atpA is also present. In addition to these regions, there are many
short sequences with homology to fragments of mitochondrial DNAs from rice or
other plants. These sequences may be remnants of multiple rearrangements of the
genome and their presence seems to explain, in part, the large sizes of the
mitochondrial genomes of higher plants.
