- Abstract:
- The reactive gas ethene is one of the best characterised growth regulators in higher plants. Ethene production has also been observed in marine macroalgae and a freshwater phytoplankton, suggesting that it may also act as a chemical signal in marine algae. Several ethene production pathways are known, including one where acrylate is a precursor. Acrylate decarboxylase has been found in beans and yeast and it was suggested that algae use this metabolic route to form ethane. Production of dimethyl sulphide (DMS) and acrylate by some marine algae is well known. This proposal is based on our observations of co-production of DMS and ethane, and field data indicating light-dependency of DMSP lyase activity, and DMS and ethane production. Our aim is to investigate the metabolic pathway of ethane production in Enteromorpha sp. and Emiliania huxleyi via physiological experiments.
