Assessment of heterosis in two Arabidopsis thaliana common-reference mapping populations. [PDF]
Hybrid vigour, or heterosis, has been of tremendous importance in agriculture for the improvement of both crops and livestock. Notwithstanding large efforts to study the phenomenon of heterosis in the last decades, the identification of common molecular ...

Origin and adaptation to high altitude of Tibetan semi-wild wheat
Mechanism of high altitude adaptation of wheat remains unknown. Here, the authors assemble the draft genome of a Tibetan semi-wild wheat accession and resequence 245 wheat accessions to reveal that Tibetan semi-wild wheat has been de-domesticated from ...

Heat stress, a major abiotic stressor of wheat (Triticum aestivum L.), often results in reduced yield and decreased quality. In this study, a proteomic method, Tags for Relative and Absolute Quantitation Isobaric (iTRAQ), was adopted to analyze the ...

Heterosis for Nitrogen Use Efficiency of Maize Hybrids Enhanced over Decades in China
The nitrogen use efficiency (NUE) of modern maize hybrids has been greatly improved, but for decades, little was known on whether the NUE heterosis of maize hybrids had increased.

AFLP Fingerprinting and Genetic Diversity of Main Sweetpotato Varieties in China
AFLP fingerprinting of the 98 main sweetpotato varieties planted in China has been constructed. Using 17 AFLP primer combinations which were selected from 1 208 primer combinations and generated the most amounts of polymorphic bands, AFLP analysis of the

Recombining your way out of trouble: the genetic architecture of hybrid fitness under environmental stress [PDF]
Hybridization between species is a fundamental evolutionary force that can both promote and delay adaptation. There is a deficit in our understanding of the genetic basis of hybrid fitness, especially in non-domesticated organisms.

Heterosis, also known as 'hybrid vigor', is a well-known phenomenon whereby hybrid offspring resulting from cross pollination exhibit greater vigor than either parent. Here, Hochholdinger and Baldauf provide an overview of this fascinating biological phenomenon and what is known about the underlying genetics and mechanisms.

Heterosis as investigated in terms of polyploidy and genetic diversity using designed Brassica juncea amphiploid and its progenitor diploid species. [PDF]
Fixed heterosis resulting from favorable interactions between the genes on their homoeologous genomes in an allopolyploid is considered analogous to classical heterosis accruing from interactions between homologous chromosomes in heterozygous plants of a

Understanding the genetic basis of rice heterosis: Advances and prospects
Heterosis, which describes the superior vigor and yield of F1 hybrids with respect to their parents, is observed in many rice hybrid crosses. The exploitation of heterosis is a great leap in the history of rice breeding.
