NUCLEOTIDE-SEQUENCE OF A 28-KBP PORTION OF RICE MITOCHONDRIAL-DNA - THE EXISTENCE OF MANY SEQUENCES THAT CORRESPOND TO PARTS OF MITOCHONDRIAL GENES IN INTERGENIC REGIONS

The nucleotide sequence of a 27,588-bp region of rice mitochondrial DN
A was determined. This sequence contains putative genes that encode in
itiator 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 fragmen
ts of mitochondrial DNAs from rice or other plants. These sequences ma
y be remnants of multiple rearrangements of the genome and their prese
nce seems to explain, in part, the large sizes of the mitochondrial ge
nomes of higher plants.
