The paper shows that algal betaine triggers bacterial hydrogen peroxide production, leading to algal death in marine interactions.

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

This study identifies Bmt as a methionine synthase that enables marine bacteria to shorten their lag phase by directly demethylating DMSP and betaine without requiring cofactors.
