An unbiased transcriptomic approach reveals that developing paddlefish electrosensory organs express genes essential for mechanosensory hair cell development and synaptic transmission, and identifies candidates for mediating electroreceptor development and function.
The core domains of an RNA helicase interact with a wide variety of NTPs and nucleic acids suggesting how related enzymes may have evolved to have diverse functions.
The first genomic view of beetle luciferase evolution indicates evolutionary independence of luciferase between fireflies and click-beetles, and provide valuable datasets which will accelerate the discovery of new biotechnological tools.
Combining in silico and experimental approaches to identify and understand the residue changes in the H-NS protein that allowed bacteria to adapt environment-sensing to different habitats.
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.
Recent functional changes in ancient duplicate genes led to the evolution of divergent regulatory and metabolic strategies by the GALactose gene networks of two yeast species.
A long-term evolution experiment with Escherichia coli shows that the appearance and optimization of a new trait can require both co-opting existing cellular pathways for new roles and reversing a history of previous adaptation.
Fish trace amine-associated receptors evolved a novel structural motif that enables the detection of chemically diverse amine odors in a non-canonical 'inverted' orientation.
