In the context of an organism's ecology, physiology, and macroevolutionary history, inheritance and gene loss can yield emergent patterns of trait variability that give the appearance of gene acquisition.
A quantitative analysis of glucose-dependent transport regulation indicates that mitochondrial accumulation in regions of high nutrient availability can enhance metabolism in neuronal axons under physiologically relevant conditions.
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.
Domestication of endosymbiotic Mollicutes may have resolved nitrogen-recycling challenges for attine ants and enabled the evolutionary derived leaf-cutting ants to fully exploit their herbivorous niches.
A high axonal chloride concentration explains why activation of light-gated chloride channels causes neurotransmitter release, and a novel hybrid somatodendritic targeting motif ameliorates this phenomenon and improves their inhibitory function.
