Genetically engineered cytoplasmic male sterility
Trends in Plant Science, 2006 Cytoplasmic male sterility, conditioned by some maternally inherited plant mitochondrial genomes, is the most expedient method to produce uniform populations of pollen-sterile plants on a commercial scale. Plant mitochondrial genomes are not currently amenable to genetic transformation, but genetic manipulation of the plastid genome allows engineering ...

Rice, 2021 Background Cytoplasmic male sterility (CMS) is a trait associated with non-functional pollen or anthers, caused by the interaction between mitochondrial and nuclear genes.

A Single Nucleotide Polymorphism Unique to the Galanthum-CMS of Onion
HortScience, 2023 Different sources of cytoplasmic male sterility (CMS) are used to produce hybrid onion seed. The most commonly used source of CMS in onion is S cytoplasm (S-CMS), and male fertility is restored by a dominant allele at the nuclear male-fertility ...

Use of cytoplasmic male sterility in sorghum breeding for productivity
Зерновое хозяйство России, 2023 The productivity increase of many agricultural crops is associated with the production of heterotic hybrid forms that are more productive than conventional varieties.

(Molecular analysis of cytoplasmic male sterility) [PDF]
, 1990 We have determined the actual RNA sequence of four mitochondrial genes: pcf, nad3, rps12, and coxII. Because plant mitochondrial proteins cannot be predicted from DNA sequences, the actual primary structures of the encoded proteins were unknown. We have gained information concerning the process of RNA editing. Editing can occur before splicing.

Molecular Oncology, EarlyView.Partial inhibition of focal adhesion kinase (FAK) can paradoxically promote tumor growth, rather than simply producing a weaker antitumor effect than that observed with strong FAK suppression. In breast cancer and melanoma models, targeting p110δ PI3K, particularly in macrophages, counteracted these tumor‐promoting effects, highlighting the importance ...

HETEROGENEITY OF MAIZE CYTOPLASMIC GENOMES AMONG MALE-STERILE CYTOPLASMS [PDF]
Genetics, 1978 ABSTRACT Maize mitochondrial and chloroplast DNA's were prepared from normal (fertile) lines or single crosses and from members of the T, C, and S groups of male-sterile cytoplasms. Restriction endonucleases HindIII, BamI, EcoRI, and SalI were used to restrict the DNA, and the resultant fragments were electrophoresed in agarose gels. The

Small RNA pathways in mammalian oocytes
FEBS Open Bio, EarlyView.Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Cytoplasmic male sterility in barley [PDF]
Physiologia Plantarum, 1980 AbstractThe maternal male sterile barley msm1 with or without a dominant gene, Rfmla, which restores male fertility, was studied. Determined with SDS‐PAGE, the polypeptide pattern in the anthers of unrestored msm1 plants remains juvenile in the middle of anther development, two major zones being absent or weak.

Genetic characterisation of a novel male sterile two-type line system 19F08AB in Brassica napus L.
Czech Journal of Genetics and Plant BreedingRapeseed (Brassica napus L.) is a major global oilseed crop and exhibits significant heterosis. The discovery and characterisation of novel male-sterile accessions remain fundamental for harnessing heterosis in rapeseed breeding. Previously, we developed
