The paper shows that some mitochondria-lacking planctomycetal bacteria can engulf prey, challenging mitochondria-first eukaryogenesis models.

The paper identifies conserved bacterial genes responsible for thallusin biosynthesis, a morphogen that influences algal development across marine and terrestrial environments.

This study shows that algal glycine betaine stimulates bacterial cobalamin production, creating a feedback loop that influences marine microbial interactions and productivity.
