Abstract – Most of higher plant species are hermaphroditic and male-sterility is often considered as an accident of development. In fact among the multiple possible causes of male-sterility, the most frequently met in nature is cytoplasmic male-sterility (cms) which is a maternally inherited trait playing an active role in the
Abstract. Cytoplasmic male sterility (CMS) is a commonly observed phenotype in higher plants, where it is described in over 140 plant species (Laser and Lersten, 1972). Viable pollen is not produced by plants exhibiting the cytoplasmic male sterility trait. Although all CMS plants are alike in that they are unable to produce
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. Contents. [hide]. 1 Background; 2 Cytoplasmic male sterility; 3 Cytoplasmic-genetic male sterility
Cytoplasmically inherited male sterility is of considerable economic importance in the production of hybrid seed for many crop plants. Recent evidence suggests that the. genes responsible for this trait are localized on mitochondrial DNA. It has been recognized since the beginning of this century that the cytoplasm of higher.
The molecular basis of cytoplasmic male sterility and fertility restoration. Patrick S. Schnable and Roger P. Wise. Cytoplasmic male sterility (CMS) is a maternally inherited condition in which a plant is unable to produce functional pollen. It occurs in many plant species and is often associated with chimeric mitochondrial open
S u m m a r y. Cytoplasmic male sterility (CMS), the trait result- ing in the formation of non-functional microspores or pollen grains, is commonly used by plant breeders for hybrid seeds production. Numerous studies aimed at the explanation of both biological and molecular mechanisms leading to the pollen abortion have
19 Dec 2005 CYTOPLASMIC GENETIC MALE STERILITY IN. PLANTS – A MOLECULAR PERSPECTIVE. K.K.Vinod. Centre for Plant Breeding and Genetics. Male sterility is defined as the failure of plants to produce functional anthers, pollen, or male gametes. First documentation of male sterility came in 1763 when.
Cytoplasmic Male Sterility and Fertility Restoration. Cytoplasmic male sterility (CMS), a condi- tion under which a plant is unable to produce functional pollen, is widespread among higher plants. CMS systems repre- sent a valuable tool in the production of hybrid seed in self-pollinating crop species, including maize, rice
Cytoplasmic male sterility (CMS) is a maternally inherited condition in which a plant is unable to produce functional pollen. It occurs in many plant species and is often associated with chimeric mitochondrial open reading frames. In a number of cases, transcripts originating from these altered open reading frames are
