The Role of Transcriptional Regulation in Hybrid Vigor [PDF]

open access: yesFrontiers in Plant Science, 2020
The genetic basis of hybrid vigor in plants remains largely unsolved but strong evidence suggests that variation in transcriptional regulation can explain many aspects of this phenomenon. Natural variation in transcriptional regulation is highly abundant in virtually all species and thus a potential source of heterotic variability.

Molecular mechanisms of polyploidy and hybrid vigor [PDF]

open access: greenTrends in Plant Science, 2010
Hybrids such as maize (Zea mays) or domestic dog (Canis lupus familiaris) grow bigger and stronger than their parents. This is also true for allopolyploids such as wheat (Triticum spp.) or frog (i.e. Xenopus and Silurana) that contain two or more sets of chromosomes from different species.

Hybrid mimics and hybrid vigor in Arabidopsis [PDF]

open access: yesProceedings of the National Academy of Sciences, 2015
Significance Hybrids have an important role in many crops used for global food production. The increased production levels of biomass and grain are restricted to the first-generation hybrid. We report stabilization of hybrid vigor traits in pure breeding hybrid mimic lines.

Hybrid Vigor in Science [PDF]

open access: yesScience, 2008
When I was president of the U.S. National Academy of Sciences, I came to believe that the future success of humanity may depend on learning to use the tools of science--including the collection of objective evidence on what works and why--at all levels of decision-making. Thus, the National Academies have repeatedly addressed questions such as "How can

Unraveling the genetic basis of hybrid vigor [PDF]

open access: yesProceedings of the National Academy of Sciences, 2006
The study of hybrid vigor and inbreeding depression traces back to Charles Darwin, who was the first scientist to examine the phenomenon in a systematic manner (1). Hybrid vigor, or heterosis, is the increase in stature, biomass, and fertility that characterizes the progeny of crosses between diverse parents such that the F1 is superior to the better ...

Hybrid Vigor in Poultry

open access: yesPoultry Science, 1927
Abstract The phenomenon of hybrid vigor is well known from the crossing of both plants and animals. The first generation hybrids resulting from the crossing of two pure breeds frequently exhibit vigor superior to either of the crossed pure breeds. The high yielding qualities of first generation hybrids in corn have been demonstrated by Jones2 and ...

Hybrid Vigor in Biophysics

open access: yesThe American Biology Teacher, 1959
One of the basic understandings we have received from genetics is the theory that hybrid vigor is an important natural occurrence. It means, in the simplest sense, when two pure strains of related organisms are crossed the resulting hybrid is usually more vigorous than either of its parents. The advantages of hybridization are well known in corn, roses,

Invited Commentary: Genes, Environment, and Hybrid Vigor [PDF]

open access: yesAmerican Journal of Epidemiology, 2009
In the 1950s, case-control studies of smoking and lung cancer established a paradigm for epidemiologic studies of risk factors for chronic diseases. Since then, thousands of case-control studies have examined possible associations of countless risk factors with numerous diseases, rarely finding associations as strong or consistent as that of smoking ...

Cultural hybridity and vigor in the decolonised architectural curriculum

open access: yesParanoá: cadernos de arquitetura e urbanismo, 1969
Descolonizar o ensino-aprendizagem em Arquitetura requer questionar o que é pertinente a uma sociedade multiracial, multicultural e multiliguistica e ao mesmo tempo adequado a uma disciplina internacionalista. Examinamos conceitos de “descolonização” e “descolonialidade” em seu desenvolvimento, especialmente no hemisfério sul e como eles podem formar ...
