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.
Selective forces imposed by the squid animal host drive rapid adaptation of non-native Vibrio fischeri bacteria through convergent mutations of large effect, unmasking preexisting coordinated regulation of symbiosis.
Environmental transmission is atypical of symbionts that have undergone genome degradation, yet genetically reduced deep-sea anglerfish symbionts likely persist in the deep sea biome in search of a new host.
ATP enters the endoplasmic reticulum (ER) lumen through an SLC35B1/AXER-dependentCaATiER mechanism, and ATP usage in the ER renders 'anti-Warburg' effect by increasing ATP regeneration from OxPhos while decreasing glycolysis.
The newly opened genome of a kleptoplastic mollusk, Plakobranchus ocellatus, indicated that sequestered plastids retain their activity within the animal cell without horizontal algal gene transfer to the animal nucleus.
