Journal ArticleDOI
Unique DNA associated with mitochondria in the "S"-type cytoplasm of male-sterile maize.
TL;DR: Mitochondrial DNAs were prepared from maize lines with normal cytoplasm and with the T, C, S, and EP sources of male-sterile cytoplasms and showed the presence of two faster migrating DNAs of molecular weight 3.42 to 3.48 x 10(6) and 4.01 to 4.10 x10(6).
Journal ArticleDOI
Heterogeneity of maize cytoplasmic genomes among male-sterile cytoplasms
D. R. Pring,Charles S. Levings +1 more
TL;DR: The marked variation in mtDNA, with apparently less variation in ctDNA, represents circumstantial, but compelling, evidence that mtDNA may be involved in the male sterility and disease susceptibility traits in maize, and indicates a possible gradation of relatedness among male-sterile cytoplasms.
Journal ArticleDOI
Mitochondrial DNA variation in maize plants regenerated during tissue culture selection.
TL;DR: The mtDNA analyses indicated that the male-fertile, toxin-resistant lines did not originate from selection of N mitochondrial genomes coexisting previously with T genomes in the T cytoplasm line used for selection.
Journal ArticleDOI
Cytoplasmic Reversion of cms-S in Maize: Association with a Transpositional Event
Charles S. Levings,B. D. Kim,D. R. Pring,M. F. Conde,Rusty J. Mans,John R. Laughnan,Susan Gabay-Laughnan +6 more
TL;DR: In this paper, the disappearance of the mitochondrial plasmid-like DNA's, S-1 and S-2, and changes in the mitochondrial chromosomal DNA are correlated with spontaneous reversion to fertility in S male-sterile cytoplasm of maize.
Journal ArticleDOI
Organelle DNA variation and systematic relationships in the genus Zea: Teosinte.
TL;DR: It was suggested that the evolutions of the chloroplast and mitochondrial DNAs may be independent of each other, that variation of organelle DNA within a species complex of an organism may be the common condition, and that the DNAs of the organelle and nuclear systems evolve in reasonable harmony.
