Morphological and fitness defects imposed on amoebae hosts by Burkholderia symbionts demonstrates symbiont species-specific effects and provides evidence of host adaptation to naturally acquired symbionts.
Parallel losses of short-wave light sensitivity in diverse bats occurred through independent changes at multiple steps in the conversion of genotype into functional phenotype, including pre-, during, and post-transcription.
A genetic screen reveals that two predicted glycosyltransferases promote rosette development and prevent cell clumping in one of the closest living relatives of animals, the choanoflagellate S. rosetta.
In potassium-dependent NTPases, insertion of the activating potassium ion into the active site leads to rotation of the gamma-phosphate yielding a near-eclipsed, catalytically productive conformation of the triphosphate chain.
The animal phylogeny of glutamate receptors indicates that vertebrate types do not account for all receptor classes originated during evolution, neither are they the pinnacle of a linear evolutive process.
