Nucleotide sequence of the S-2 mitochondrial DNA from the S cytoplasm of maize

RESUMO
Mitochondria from the S male-sterile cytoplasm (cms-S) of maize contain two plasmid-like DNAs, S-1 and S-2, that appear to be prominently involved with the cytoplasmic male sterility trait. The complete nucleotide sequence of the S-2 DNA molecule was determined by the chain termination method. The linear S-2 DNA molecule contains 5,452 base pairs and is terminated by exact 208-base-pair inverted repetitions. Two large open reading frames were identified in the S-2 DNA, suggesting the possibility of protein-encoding genes. The nucleotide sequence of the S-2 termini are discussed with regard to models proposed for the replication of linear DNA molecules.
