Gene Induced Mutation of a Heritable Cytoplasmic Factor Producing Male Sterility in Maize

Thoughts on Cytoplasmic Male Sterility in cms-T Maize.

The 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...

Cytoplasmic 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 ...

The Interaction of Nuclear and Cytoplasmic Factors in the Inheritance of Male Sterility in Maize.

ALE sterility in plants is of unusual interest since its inheritance is due M to a number of different mechanisms. In the early days of genetics a controversy existed as to the relative importance of the nucleus and the cytoplasm in inheritance. Many investigators believed the nucleus was all-important and relegated the cytoplasm to a non-essential role. That the cytoplasm did not always play a...

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...
