Physical and chemical interactions with bacteria influence the life and death of Emiliania huxleyi, a bloom-forming micro-alga important in global biogeochemical cycles.

Dynamic successive blooms of clades of planktonic marine bacteria that can be observed during blooms of marine algae follow discernible patterns, part of which might be explained by substrate-induced forcing.

A novel dimethylsulfoniopropionate lyase was identified, which catalyzes dimethyl sulfide releasing by a new mechanism and is found in several bacterial lineages, revealing its important roles in global sulfur cycling.

Beneficial symbiotic bacteria encode an exceptional number of toxin-related genes that are all expressed by the symbionts in the host, supporting their key role in host-microbe interactions.
