Potential Association of Reactive Oxygen Species With Male Sterility in Peach

Frontiers in Plant Science, 2021
Male sterility is an important agronomic trait for hybrid vigor utilization and hybrid seed production, but its underlying mechanisms remain to be uncovered.

High-resolution genome-wide dissection of the two rules of speciation in Drosophila. [PDF]

PLoS Biology, 2007
Postzygotic reproductive isolation is characterized by two striking empirical patterns. The first is Haldane's rule--the preferential inviability or sterility of species hybrids of the heterogametic (XY) sex.

Gene, protein and network of male sterility in rice

Frontiers in Plant Science, 2013
Rice is one of the most important model crop plants whose heterosis has been well exploited in commercial hybrid seed production via a variety of types of male sterile lines. Hybrid rice cultivation area is steadily expanding around the world, especially

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.

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 ...

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

Molecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

A yeast model of 5‐oxoproline accumulation reveals a general toleration to 5‐oxoproline

FEBS Open Bio, EarlyView.
Using a yeast model, we show that even high accumulation of 5‐oxoproline causes only mild cellular stress and does not trigger oxidative stress. Instead, cells adapt by activating efflux pumps and diverse protective pathways, suggesting that previously proposed harmful effects of 5‐oxoproline may arise from indirect metabolic imbalances rather than the

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.
