February 26,University of East Anglia Credit: CC0 Public Domain Researchers at the University of East Anglia have discovered a key gene for the synthesis of one of the world's most abundant sulfur molecules.

Dimethylsulfoniopropionate DMSP is an important nutrient in marine environments with more than one billion tonnes produced annually by marine phytoplankton microscopic plant-like cellsseaweed and bacteria.

When marine microorganisms break down DMSP, they release a climate-cooling gas called dimethylsulfide DMSwhich also gives the seaside its characteristic smell.

The discovery of a gene named DSYB responsible for synthesising DMSP, published today in Nature Microbiology, represents a huge step forward in the field of sulfur cycling in marine environments.

It could also allow scientists to better predict the impact of climate change on DMSP production. The team discovered that this gene, and therefore DMSP synthesis itself, likely originated in marine bacteria and was later passed onto phytoplanktonwhich have evolved to be marine factories for this molecule.

Across the world's oceans, seas and coasts, tens of millions of tonnes of it are released by microbes that live near plankton and marine plants, including seaweeds and some salt-marsh grasses.

These same clouds are vital in the movement of large amounts of sulfur from the oceans to land, making the production of DMSP and DMS a critical step in the global sulfur cycle.

Until now, we didn't know any of the phytoplankton genes responsible for the synthesis of this highly abundant marine nutrient. This discovery represents a huge step forward in the field of sulfur cycling in marine environments.

Also, because it is involved in such a critical step in the synthesis pathway, the regulation of the DSYB gene by environmental conditions is of great significance in determining how much DMSP is ultimately produced.

This suggests that bacteria may play an even more important role in global DMSP synthesis, both historically and in the present day.• Chloroplasts contain DNA and ribosomes allowing them to synthesise proteins needed in the light dependent reaction.
