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.
Plasmodium parasite transcription shifts dramatically along asexual development, and transmission stages variably express important immune evasion genes, suggesting much interesting biology has until now been hidden by bulk analyses.
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.
Experiments and mathematical modelling show that rare nitrogen fixing symbionts invade a population dominated by non-fixing bacteria across plant generations, above a threshold of a combination of ecological factors.
Physiological differentiation during symbiosis leads to division of labor between smaller and larger cells in an uncultured bacterial tubeworm symbiont population and results in remarkable metabolic diversity and complexity.
