Genetic Mechanism of Hybrid Sterility and Utilization of Indica-japonica Inter-subspecific Heterosis in Rice

Guangdong nongye kexue, 2022
Asian-cultivated rice (Oryza sativa L.) consists of two subspecies, indica (Oryza sativa L. indica) and japonica (Oryza sativa L. japonica) subspecies. There are considerable differences between them in morphology, physiology and gene level. The stronger

Epistasis among Drosophila persimilis factors conferring hybrid male sterility with D. pseudoobscura bogotana. [PDF]

PLoS ONE, 2010
The Bateson-Dobzhansky-Muller model posits that hybrid incompatibilities result from genetic changes that accumulate during population divergence.

Molecular mapping of a novel locus S68 for intrasubspecific hybrid sterility in indica-indica hybrid [PDF]

Scientific Reports
Oryza. sativa subsp. indica, a subspecies of Asian cultivated rice, plays a crucial role in global rice production, particularly in the utilization of hybrid vigor.

A novel approach identifying hybrid sterility QTL on the autosomes of Drosophila simulans and D. mauritiana. [PDF]

PLoS ONE, 2013
When species interbreed, the hybrid offspring that are produced are often sterile. If only one hybrid sex is sterile, it is almost always the heterogametic (XY or ZW) sex.

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 ...

Starmaya: The First Arabica F1 Coffee Hybrid Produced Using Genetic Male Sterility [PDF]

Frontiers in Plant Science, 2019
In the present paper, we evaluated the implementation of a seed production system based on the exploitation of male sterility on coffee. We studied specifically the combination between CIR-SM01 and Marsellesa® (a Sarchimor line), which provides a hybrid ...

Alternatively spliced killer–protector system confers S19-mediated hybrid male sterility in rice [PDF]

Nature Communications
Hybrid sterility limits the use of strong interspecific heterosis and S19 is a major locus that confers hybrid sterility between Oryza sativa (Asian cultivated rice) and Oryza glaberrima (African cultivated rice).

Modulation of Prdm9-controlled meiotic chromosome asynapsis overrides hybrid sterility in mice. [PDF]

Elife, 2018
Hybrid sterility is one of the reproductive isolation mechanisms leading to speciation. Prdm9, the only known vertebrate hybrid-sterility gene, causes failure of meiotic chromosome synapsis and infertility in male hybrids that are the offspring of two ...
