Cytoplasmic Male Sterility Contributes to Hybrid Incompatibility Between Subspecies of Arabidopsis lyrata
In crosses between evolutionarily diverged populations, genomic incompatibilities may result in sterile hybrids, indicating evolution of reproductive isolation. In several plant families, crosses within a population can also lead to male sterile progeny because of conflict between the maternally and biparentally inherited genomes. We examined hybrid fertility between subspecies of the perennial...
متن کاملDevelopment of cytoplasmic-nuclear male sterility, its inheritance, and potential use in hybrid pigeonpea breeding.
Pigeonpea [Cajanus cajan (L.) Millsp.] is a unique food legume because of its partial (20-30%) outcrossing nature, which provides an opportunity to breed commercial hybrids. To achieve this, it is essential to have a stable male-sterility system. This paper reports the selection of a cytoplasmic-nuclear male-sterility (CMS) system derived from an interspecific cross between a wild relative of p...
متن کاملA simple genetic incompatibility causes hybrid male sterility in mimulus.
Much evidence has shown that postzygotic reproductive isolation (hybrid inviability or sterility) evolves by the accumulation of interlocus incompatibilities between diverging populations. Although in theory only a single pair of incompatible loci is needed to isolate species, empirical work in Drosophila has revealed that hybrid fertility problems often are highly polygenic and complex. In thi...
متن کاملCytoplasmic Male Sterility and Fertility Restoration
Cytoplasmic male sterility (CMS), a condition under which a plant is unable to produce functional pollen, is widespread among higher plants. CMS systems represent a valuable tool in the production of hybrid seed in self-pollinating crop species, including maize, rice, cotton, and a number of vegetable crops. Hybrids often exhibit heterosis, more commonly known as hybrid vigor, whereby hybrid pr...
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...
