A cryptic cytoplasmic male sterility unveils a possible gynodioecious past for Arabidopsis thaliana. [PDF]

open access: yesPLoS ONE, 2013
Gynodioecy, the coexistence of hermaphrodites and females (i.e. male-sterile plants) in natural plant populations, most often results from polymorphism at genetic loci involved in a particular interaction between the nuclear and cytoplasmic genetic ...

(Molecular analysis of cytoplasmic male sterility) [PDF]

open access: yes, 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.

Some cytological and ultrastructural aspects of male sterility in Impatiens

open access: yesActa Societatis Botanicorum Poloniae, 2014
Some cytological and ultrastructural aspects of tapetum and sporogenic cells, in both male-fertile and male-sterile Impatiens, were investigated and compared in order to find the cause of cytoplasmic male sterility.

Mitochondrial localization of ORF346 causes pollen abortion in alloplasmic male sterility

open access: yesCrop Journal, 2021
The Nsa cytoplasmic male sterility (CMS) system confers stable male sterility and offers great potential for production of hybrid seeds in oilseed rape. However, genes responsible for male sterility in Nsa CMS have not been identified.

Epigenetic silencing of the liver‐specific lncRNA LUNAR promotes liver cancer progression via NOTCH activation

open access: yesMolecular Oncology, EarlyView.
LUNAR is a liver‐specific long noncoding RNA (lncRNA) that is highly expressed in normal liver but becomes epigenetically silenced in hepatocellular carcinoma through promoter hypermethylation. Loss of LUNAR is associated with NOTCH activation, epithelial–mesenchymal transition, and metastasis, whereas restoring LUNAR restrains metastatic progression ...

Derivation and characterization of retinal pigment epithelium from urine‐derived iPSCs

open access: yesFEBS Open Bio, EarlyView.
Age‐related macular degeneration causes vision loss via RPE dysfunction and loss. Traditional iPSC therapies rely on invasive biopsies, limiting scalability. Here, we utilize urine‐derived stem cells as an accessible source to generate u‐iPSCs, successfully differentiated into pigmented RPE. This “Urine‐to‐Retina” platform provides a promising path for

Genetic characterisation of a novel male sterile two-type line system 19F08AB in Brassica napus L.

open access: yesCzech Journal of Genetics and Plant Breeding
Rapeseed (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

PEPPER (CAPSICUM ANNUUM L.) CYTOPLASMIC MALE STERILTY [PDF]

open access: yesJournal of Central European Agriculture, 2002
In the present study the molecular basis and mechanism of pepper cytoplasmic male sterility (CMS) and its restoration system (Rf) has been characterized in detail. Pollen fertility of five CMSs (No. 201 to 205), four restorer lines (No. 206, 207, 209 and

Small RNA pathways in mammalian oocytes

open access: yesFEBS 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 ...

Advances in plant male sterility for hybrid seed production: an overview of conditional nuclear male sterile lines and biotechnology-based male sterile systems

open access: yesFrontiers in Plant Science
Male sterility forms the foundation of hybrid seed production technology in field crops. A variety of genetically controlled male sterility/fertility systems starting with cytoplasmic male sterility (CMS), genic male sterility (GMS) including conditional
