Cytoplasmic male sterility in quinoa

Euphytica, 1992
The quinoa cultivar ‘Apelawa’ carries both normal and male sterile cytoplasms. Plants with male sterile cytoplasm produce flowers characterized by the complete absence of anthers and prominent exsertion of stigmas. Intraspecific crosses between male sterile quinoa plants and normal male fertile pollen donors consistently produced male sterile offspring

Cytoplasmic Male Sterility

1983
The trait cytoplasmic male sterility (cms) is common in higher plants. Edwardson (1) reported that the cms trait had been observed in at least eighty unique plant species. Although the trait may manifest itself in different fashions among the various species, cms plants have in common the inability to produce viable pollen.

Nucleoli and cytoplasmic male sterility

Zeitschrift für Vererbungslehre, 1965
The paper describes the relation of cytoplasmic male sterility and the differentiation of nucleoli. Defects in the formation of nucleoli of pollen grains of maize with cytoplasmic male sterility were observed whereas the nuclei of control, i.e. fertile maize contained always only a single nucleole.

Cytoplasmic Male Sterility in Petunia

1991
A maternally-inherited male sterile phenotype is known in many plant genera, including Petunia (Laser and Lersten, 1972; Hanson and Conde, 1985). As all seed on a cytoplasmic male sterile (CMS) plant must result from cross-pollination, the trait has attracted commercial interest for hybrid seed production.

Cytoplasmic male sterility in Plantago lanceolata L.: differences between male-sterile cytoplasms at the DNA- and RNA-level

Theoretical and Applied Genetics, 1987
To establish the feasibility of a cytoplasmtype assay based on molecular hybridizations, mitochondrial DNAs from the two male-sterile cytoplasms of Plantago lanceolata (P and R) were compared by restriction endonuclease digestion. We cloned a 1.1 kbp Eco RI-HindIII fragment from P-mtDNA (pPl-311), which on hybridization to Southern blots of Bam HI ...

Gene-Cytoplasmic Male Sterility

1988
Typically, mst represents a condition in which female sex is normal and male sex is nonfunctional. Two types of nuclear genes, fr and ms, control this sterility. The action of ms genes is cytoplasm-insensitive, whereas fr gene action is cytoplasm- dependent and -sensitive as these genes act only in a certain cytoplasm type, the S-cytoplasm.

The Texas Cytoplasm of Maize: Cytoplasmic Male Sterility and Disease Susceptibility

Science, 1990
The Texas cytoplasm of maize carries two cytoplasmically inherited traits, male sterility and disease susceptibility, which have been of great interest both for basic research and plant breeding. The two traits are inseparable and are associated with an unusual mitochondrial gene, T- urf13 , which encodes a 13 ...
