Identifying yield-related genes in maize based on ear trait plasticity

Genome Biology, 2023
Background Phenotypic plasticity is defined as the phenotypic variation of a trait when an organism is exposed to different environments, and it is closely related to genotype. Exploring the genetic basis behind the phenotypic plasticity of ear traits in

Rapid evolution in response to introduced predators II: the contribution of adaptive plasticity

BMC Evolutionary Biology, 2007
Background Introductions of non-native species can significantly alter the selective environment for populations of native species, which can respond through phenotypic plasticity or genetic adaptation.

[Phenotypic plasticity in insects].

Biologie aujourd'hui, 2020
Les insectes représentent 85 % des animaux. Ils se sont adaptés à de nombreux environnements et jouent un rôle majeur dans les écosystèmes. De nombreuses espèces d'insectes montrent de la plasticité phénotypique. Nous présentons ici les mécanismes impliqués dans la plasticité phénotypique chez différents insectes (les pucerons, le criquet migrateur, le

The REDOX balance in the prefrontal cortex is positively modulated by aerobic exercise and altered by overfeeding

Scientific Reports
While obesity rates increase worldwide, physical activity levels are reduced. Obesity and physical inactivity may be inversely related to the production of reactive oxygen species (ROS) and cause oxidative stress in the central nervous system.

Weak gene–gene interaction facilitates the evolution of gene expression plasticity

BMC Biology, 2023
Background Individual organisms may exhibit phenotypic plasticity when they acclimate to different conditions. Such plastic responses may facilitate or constrain the adaptation of their descendant populations to new environments, complicating their ...

Phenotypic plasticity in nematodes [PDF]

Worm, 2012
Model systems, including C. elegans, have been successfully studied to understand the genetic control of development. A genotype's phenotype determines its evolutionary fitness in natural environments, which are typically harsh, heterogeneous and dynamic.

Phenotypic Plasticity in Bacterial Plasmids [PDF]

Genetics, 2004
AbstractPlasmid pB15 was previously shown to evolve increased horizontal (infectious) transfer at the expense of reduced vertical (intergenerational) transfer and vice versa, a key trade-off assumed in theories of parasite virulence. Whereas the models predict that susceptible host abundance should determine which mode of transfer is selectively ...

Increased phenotypic plasticity to climate may have boosted the invasion success of polyploid Centaurea stoebe.

PLoS ONE, 2012
Phenotypic plasticity may allow organisms to cope with altered environmental conditions as e.g. after the introduction into a new range. In particular polyploid organisms, containing more than two sets of chromosomes, may show high levels of plasticity ...

Phenotypic plasticity and diversity in insects [PDF]

Philosophical Transactions of the Royal Society B: Biological Sciences, 2010
Phenotypic plasticity in general and polyphenic development in particular are thought to play important roles in organismal diversification and evolutionary innovation. Focusing on the evolutionary developmental biology of insects, and specifically that of horned beetles, I explore the avenues by which phenotypic plasticity and polyphenic development ...
