Genomic networks of hybrid sterility. [PDF]
Hybrid dysfunction, a common feature of reproductive barriers between species, is often caused by negative epistasis between loci ("Dobzhansky-Muller incompatibilities").

New Insights Into the Nature of Interspecific Hybrid Sterility in Rice [PDF]
Interspecific and intraspecific hybrid sterility is a typical and common phenomenon of postzygotic reproductive barrier in rice. This is an indicator of speciation involved in the formation of new species or subspecies, and it significantly hampers the ...

Hybrid Sterility, Genetic Conflict and Complex Speciation: Lessons From the Drosophila simulans Clade Species [PDF]
The three fruitfly species of the Drosophila simulans clade— D. simulans, D. mauritiana, and D. sechellia— have served as important models in speciation genetics for over 40 years.

Improving bridge effect to overcome interspecific hybrid sterility by pyramiding hybrid sterile loci from Oryza glaberrima [PDF]
In order to evaluate the genetic effect caused by hybrid sterile loci, NILs with O. glaberrima fragment at six hybrid sterile loci under O. sativa genetic background (single-locus-NILs) were developed; two lines harboring two hybrid sterile loci, one ...

Mechanisms of Transmission Ratio Distortion at Hybrid Sterility Loci Within and Between Mimulus Species [PDF]
Hybrid incompatibilities are a common correlate of genomic divergence and a potentially important contributor to reproductive isolation. However, we do not yet have a detailed understanding of how hybrid incompatibility loci function and evolve within ...

Understanding the Nature of Hybrid Sterility and Divergence of Asian Cultivated Rice [PDF]
Intraspecific hybrid sterility is a common form of postzygotic reproductive isolation in Asian cultivated rice, which is also the major obstacle to utilize the strong heterosis in the rice breeding program.

Development of Wide-Compatible Indica Lines by Pyramiding Multiple Neutral Alleles of Indica–Japonica Hybrid Sterility Loci [PDF]
Since the development of indica hybrid rice in the 1970s, great success has been achieved in hybrid rice production in China and around the world. The utilization of inter-subspecific indica–japonica hybrid rice has always been considered due to its ...

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

SEX-LINKED HYBRID STERILITY IN A BUTTERFLY [PDF]
Recent studies, primarily in Drosophila, have greatly advanced our understanding of Haldane's rule, the tendency for hybrid sterility or inviability to affect primarily the heterogametic sex (Haldane 1922). Although dominance theory (Turelli and Orr 1995) has been proposed as a general explanation of Haldane's rule, this remains to be tested in female ...

Identification and Genetic Analysis of Collinearity Loci for Interspecific Hybrid Sterility in Genus Oryza [PDF]
Background Hybrid sterility is a common phenomenon in hybrids between the Asian cultivated rice (Oryza sativa L.) and its relatives with AA genome, which limits the utilization of interspecific heterosis and favorable gene introgression.
