Speaker: Dr Hendrik Schäfer, University of Warwick

Summary:

The aerial parts of plants are a habitat for epiphytic microorganisms, termed the phyllosphere. The role these microorganisms play in the biogeochemical cycling of plant-derived volatiles is becoming increasingly evident. Current phyllosphere research in my group is addressing the structure and function associated with plant phyllospheres in two different systems. I will give an overview of work we are doing to characterize dimethylsulfide (DMS)-degrading microorganisms associated with the cordgrass Spartina anglica, a halophyte thriving in salt marshes which produces dimethylsulfoniopropionate (DMSP), a precursor for DMS which affects atmospheric chemistry. Approaches include high throughput sequencing, stable isotope probing and metagenomics to identify organisms and pathways that contribute to DMS cycling. In another project, we are investigating organisms degrading organic pollutants in tree phyllosphere communities using a combination of cultivation-dependent and cultivation-independent approaches. 

Hendrik will be hosted by Professor Rob Mackenzie. If you wish to meet Hendrik before/after the seminar please do get in touch.
