The genetic basis of hybrid male sterility in sympatric Primulina species

BMC Evolutionary Biology, 2020
Background Sympatric sister species provide an opportunity to investigate the genetic mechanisms and evolutionary forces that maintain species boundaries.

A hybrid sterile locus leads to the linkage drag of interspecific hybrid progenies

Plant Diversity, 2020
Interspecific hybridization plays an important role in rice breeding by broadening access to desirable traits such as disease resistance and improving yields.

Widespread over-expression of the X chromosome in sterile F₁hybrid mice. [PDF]

PLoS Genetics, 2010
The X chromosome often plays a central role in hybrid male sterility between species, but it is unclear if this reflects underlying regulatory incompatibilities.

Aborting meiosis overcomes hybrid sterility [PDF]

, 2020
AbstractHybrids between species or diverged lineages contain fundamentally novel genetic combinations but an impaired meiosis often makes them evolutionary dead ends. Here, we explored to what extent and how an aborted meiosis followed by a return-to-growth (RTG) promotes recombination across a panel of 20 yeast diploid backgrounds with different ...

Identification of S23 causing both interspecific hybrid male sterility and environment-conditioned male sterility in rice

Rice, 2019
Background Oryza glumaepatula represents an important resource of genetic diversity that can be used to improve rice production. However, hybrid sterility severely restricts gene flow between Oryza species, and hinders the utilization of distant ...

BISEXUAL HYBRID STERILITY IN DROSOPHILA MELANOGASTER [PDF]

Genetics, 1978
ABSTRACT A new type of hybrid sterility was investigated in D. melanogaster. Matings between strain 27 males from Para Wirra, South Australia, and Canton-S females produce 70-80% fully sterile male and female progeny. Strain 27 males produce sterile progeny when crossed to females of other geographic origins, but produce fertile progeny ...

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Harnessing Fungal Biowelding for Constructing Mycelium‐Engineered Materials

Advanced Engineering Materials, EarlyView.
Mycelium‐bound composites (MBCs) offer low‐carbon alternatives for construction, yet interfacial bonding remains a critical challenge. This review examines fungal biowelding as a biocompatible adhesive, elucidating mycelium‐mediated interfacial mechanisms and their role in material assembly. Strategies to optimize biowelding are discussed, highlighting

Hybrid Sterility Locus on Chromosome X Controls Meiotic Recombination Rate in Mouse. [PDF]

PLoS Genetics, 2016
Meiotic recombination safeguards proper segregation of homologous chromosomes into gametes, affects genetic variation within species, and contributes to meiotic chromosome recognition, pairing and synapsis.

A Smart Bio‐Battery Facilitates Diabetic Bone Defect Repair Via Inducing Macrophage Reprogramming and Synergistically Modulating Bone Remodeling Coupling

Advanced Functional Materials, EarlyView.
This research presents a novel implantable bio‐battery, GF‐OsG, tailored for diabetic bone repair. GF‐OsG generates microcurrents in high‐glucose conditions to enhance vascularization, shift macrophages to the M2 phenotype, and regulate immune responses.
