Genetic consequences of the couplet cytoplasmic pollen sterility and pollen migration.
ATSON and CASPARI (1960) developed a mathematical model to study the VU behavior of cytoplasmic pollen sterility in populations. They dealt with a population possessing two kinds of cytoplasm and pollen sterility resulting from an interaction of the recessive homozygote with one of the cytoplasms. Under these conditions the frequencies of the maternally transmitted cytoplasms remained unchanged...
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 کاملThe Influence of Cytoplasmic Pollen Sterility on Gene Exchange between Populations.
YTOPLASMICALLY conditioned pollen sterility occurs rather frequently in plants. Usually, the character “pollen sterility” is produced when a particular cytoplasm is combined with a recessive gene in homozygous condition in the same plant. The best investigated example is the pollen sterility in corn (reviewed by DUVICK 1965), but similar conditions have been described in a large number of plant...
متن کاملEffective Long-Distance Pollen Dispersal in Centaurea jacea
BACKGROUND Agri-environment schemes play an increasingly important role for the conservation of rare plants in intensively managed agricultural landscapes. However, little is known about their effects on gene flow via pollen dispersal between populations of these species. METHODOLOGY/PRINCIPAL FINDINGS In a 2-year experiment, we observed effective pollen dispersal from source populations of C...
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 ...
