These tiny reef fish harbor luminous bacteria, and the chromosome-level assembly of the species’ genome may facilitate the duo’s use as a vertebrate model for symbiosis.
Phylogenomics data place the enigmatic plankton in the middle of the algal family tree, despite their apparent lack of plastids—an organelle characteristic of all other algae.
Jumping genes in bdelloid rotifers are tamped down by DNA methylation performed by an enzyme pilfered from bacteria roughly 60 million years ago, a study finds.
