Phenotypic Plasticity in Bacterial Plasmids

Phenotypic 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 ...

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...

Phenotypic 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...
