Cytoplasmic Genetic Male Sterility in Plants – a Molecular Perspective
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 Kölreuter observed anther abortion within species and specific hybrids. It is more prevalent than female sterility, probably because, male sporophyte and gametophyte less protected from environment than ovule and embryo sac. Male ster...
متن کاملSuppressed expression of Retrograde-Regulated Male Sterility restores pollen fertility in cytoplasmic male sterile rice plants.
Conflict/reconciliation between mitochondria and nuclei in plants is manifested by the fate of pollen (viable or nonviable) in the cytoplasmic male sterility (CMS)/fertility restoration (Rf) system. Through positional cloning, we identified a nuclear candidate gene, RETROGRADE-REGULATED MALE STERILITY (RMS) for Rf17, a fertility restorer gene for Chinese wild rice (CW)-type CMS in rice (Oryza s...
متن کاملTransgenic induction of mitochondrial rearrangements for cytoplasmic male sterility in crop plants.
Stability of the mitochondrial genome is controlled by nuclear loci. In plants, nuclear genes suppress mitochondrial DNA rearrangements during development. One nuclear gene involved in this process is Msh1. Msh1 appears to be involved in the suppression of illegitimate recombination in plant mitochondria. To test the hypothesis that Msh1 disruption leads to the type of mitochondrial DNA rearran...
متن کاملThe Role of Non-Coding RNAs in Cytoplasmic Male Sterility in Flowering Plants
The interactions between mitochondria and nucleus substantially influence plant development, stress response and morphological features. The prominent example of a mitochondrial-nuclear interaction is cytoplasmic male sterility (CMS), when plants produce aborted anthers or inviable pollen. The genes responsible for CMS are located in mitochondrial genome, but their expression is controlled by n...
متن کاملMolecular Genetics of Mitochondrial Respiratory/ATP-Related Genes in Relation to Cytoplasmic Male-Sterility of Higher Plants
With the sequencing of the entire mitochondrial genome for some species, including Arabidopsis thaliana, Brassica napus, Beta vulgaris, Marchantia polymorpha, Oryza sativa, and Zea mays it is promising to explore the molecular genetics of mitochondrial respiratoryrelated genes in relation to some special traits with an emphasis on cytoplasmic male-sterility unique to plant mitochondria. Mitocho...
