Transfer 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...
متن کاملThe Possible Role of Atp6 Gene in Cytoplasmic Male Sterility in WA (Wild Abortive) Type of Rice (Oryza sativa L.)
The possibility of occurrence of some rearrangements inside and or around coxII and atp6 genes and their relationship with male sterility in rice lines having wild abortive (WA) cytoplasm was studied. Two sterile (IR58025A and IR62829A) and two maintainer lines (IR58025B and IR62829B) were used. Radioactive Southern blotting was employed to carry out the experiments. The hybridization of coxII...
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 کاملPentatricopeptide-repeat family protein RF6 functions with hexokinase 6 to rescue rice cytoplasmic male sterility.
Cytoplasmic male sterility (CMS) has been extensively used for hybrid seed production in many major crops. Honglian CMS (HL-CMS) is one of the three major types of CMS in rice and has contributed greatly to food security worldwide. The HL-CMS trait is associated with an aberrant chimeric mitochondrial transcript, atp6-orfH79, which causes pollen sterility and can be rescued by two nonallelic re...
