Abstract

Mitochondrial DNA from male-sterile lines of maize carrying S cytoplasm contains two small DNA species which are absent from N (fertile) and other male-sterile cytoplasms. Portions of these species have been purified and amplified by constructing recombinant plasmids in vitro. Probes made with these plasmids have been used to demonstrate; i) a homologous region in the N mitochondrial genome, which may indicate the origin of the S specific DNA species. ii) two other DNA species present in low amounts in S cytoplasm only. iii) the absence of strong homology to the S specific DNA species in mitochondria from C and T male-sterile cytoplasms.
