Symbiosis
What is in store for the guppy? Variation is essential to understanding the genetics underlying biological processes. The guppy provides a huge amount of natural variation that can be studied genetically. This variation has not been produced by mutagenesis screens, but instead has been shaped by natural selection. Thus, combined with emerging genomic resources, the guppy is an ideal organism fo...
متن کاملElectrifying symbiosis.
A role of ion channels in the interactions between bacterial pathogens and their animal hosts is well established. In some cases, regulation of endogenous channels in the target species is disrupted by bacterial toxins, resulting in an alteration of ion flux and a perturbation of cellular function (1). In a more extreme example, hemolytic bacteria actually insert poreforming proteins into the p...
متن کاملSymbiosis-independent and symbiosis-incompetent mutants of Bdellovibrio bacteriovorus 109J.
Symbiosis-independent (Sin) mutants were isolated from the symbiosis-dependent and symbiosis-competent (Sdcomp+) Bdellovibrio bacteriovorus 109J. Independently isolated Sin mutants were examined for their symbiosis competence and most were found to be comp+. Bdellovibrios comp- were selected from the Sincomp+ mutants. The Sincomp+ bdellovibrios are always at a selective disadvantage, either aga...
متن کاملSymbiosis, Synergy and Modularity: Introducing the Reciprocal Synergy Symbiosis Algorithm
Symbiosis, the collaboration of multiple organisms from different species, is common in nature. A related phenomenon, symbiogenesis, the creation of new species through the genetic integration of symbionts, is a powerful alternative to crossover as a variation operator in evolutionary algorithms. It has inspired several previous models that use the repeated composition of pre-adapted entities. ...
متن کاملBrain-computer symbiosis.
The theoretical groundwork of the 1930s and 1940s and the technical advance of computers in the following decades provided the basis for dramatic increases in human efficiency. While computers continue to evolve, and we can still expect increasing benefits from their use, the interface between humans and computers has begun to present a serious impediment to full realization of the potential pa...
