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 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...
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 کاملCytoplasmic male sterility in Brassicaceae crops
Brassicaceae crops display strong hybrid vigor, and have long been subject to F1 hybrid breeding. Because the most reliable system of F1 seed production is based on cytoplasmic male sterility (CMS), various types of CMS have been developed and adopted in practice to breed Brassicaceae oil seed and vegetable crops. CMS is a maternally inherited trait encoded in the mitochondrial genome, and the ...
متن کاملTransfer of Cytoplasmic Male Sterility into Rice
Transfer of Cytoplasmic Male Sterility into Rice Diversifying the existing cytoplasmic male sterility (CMS) sources of rice is indispensable for a sustainable production system of hybrid seed. Ahmadikhah et al. report that maintainer line Yosen B was converted to a CMS line (Yosen A) in three generations by markerassisted backcrossing. The recurrent parent genome content of the final CMS line w...
