Cytoplasmic male sterility is total or partial male sterility in plants as the result of specific nuclear and mitochondrial interactions. Male sterility is the failure of plants to produce functional anthers, pollen, or male gametes. Background - Cytoplasmic-genetic male - In hybrid breeding. Cytoplasmic male sterility (CMS), a condition under which a plant is unable to produce functional pollen, is widespread among higher plants. CMS systems. Cytoplasmic male sterility. Male sterility in plants is often cytoplasmically based and maternally inherited. Male sterile plants produce no functional pollen, but do produce viable eggs. Cytoplasmic male sterility is used in agriculture to facilitate the production of hybrid seed.

The plant trait cytoplasmic male sterility (CMS) is determined by the mitochondrial genome and is associated with a pollen sterility phenotype that can be suppressed or counteracted by nuclear genes known as restorer-of-fertility genes. Cytoplasmic Male Sterility (cms). Reference work entry. First Online: 16 July . DOI: Downloads. Cytoplasmic male sterility (CMS) is a commonly observed phenotype in higher plants, where it is described in over plant species (Laser and Lersten, ).

Male sterility is the inability of the plant to produce functional anthers or pollen, through chromosomal aberrations, gene action, or cytoplasmic influences. 30 May - 7 min - Uploaded by Hannah Contois Extra credit assignment for PLB in which we (Hannah Contois and Amber Tepe) explain. Cytoplasmic male sterility (CMS) factors have long been known in some wild plants, and also in some domesticated species, where they are. Cytoplasmic male sterility (CMS) is another trait applicable to F1 seed production, which is stable and applicable to all Brassicaceae crops. CMS is a maternally.
