Phenotypic plasticity in nematodes
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, the process by which one genome can produce different phenotypes in response to the environment, allows genotypes to b...
متن کاملPhenotypic plasticity and developmental innovations in nematodes.
Developmental plasticity has been implicated as a facilitator for phenotypic diversification, but the molecular mechanisms controlling it are largely unknown. We review recent comparative analyses in non-Caenorhabditis nematodes that display polyphenisms in larval development, mouth morphology and reproductive mode. Some of the challenges ahead will be to connect how these phenotypic traits are...
متن کاملPredatory feeding behaviour in Pristionchus nematodes is dependent on phenotypic plasticity and induced by serotonin.
Behavioural innovation and morphological adaptation are intrinsically linked but their relationship is often poorly understood. In nematodes, a huge diversity of feeding morphologies and behaviours can be observed to meet their distinctive dietary and environmental demands. Pristionchus and their relatives show varied feeding activities, both consuming bacteria and also predating other nematode...
متن کاملPhenotypic Plasticity in Skeletal Muscle
Anyone training for a marathon knows that although the goal may at first seem unattainable, with the correct exercise regime, even the least promising athlete will eventually cross the finish line. This remarkable phenotypic plasticity, which allows us to reshape our bodies within the strictures of our genetic make-up, has fascinated scientists for the last 3 decades. However, Hans Hoppeler exp...
متن کاملPhenotypic plasticity in bacterial plasmids.
Plasmid 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 favored, host density failed to mediate the trade-off in ...
