Marcus SchicklbergerProject:  Optimizing plant-microbe interactions for sustainable supply of nitrogen for bioenergy crops

The ultimate goal of this project is to develop eco-friendly economically sustainable bioenergy crops in the future by decreasing their dependency on fertilizer use.

Nitrogen (N) is an essential component of DNA and proteins and consequently, a key element for life and cell development. Mineral N is often limited in plants, which negatively affects plant growth and hence biomass yields. In natural ecosystems, microbes play a fundamental role in producing bioavailable N for plants. The plant rhizosphere, for example, contains diazotrophic (N-fixing) bacteria without the requirement of forming mutualistic association with a plant host. Recently, diazotrophic endophytic bacteria colonizing roots, stems and leaves in several non-legume plants, have been identified. To better understand and optimize interactions between bioenergy crops and diazotrophic endophytes, my project incorporates a two-tiered scientific approach: identification and isolation of diazotrophic endophytes as well as discovery of new principles and molecular mechanisms in plant-microbe interactions.

Angelica Pettenato (Research Assistant)
Angelica PettenatoAngelica Pettenato has been working as a research assistant under Romy Chakraborty since 2011. She currently works on characterization of anaerobic environmental microbes from Oakridge FRC as part of the ENIGMA project and Alaskan permafrost as a part of the Next-Generation Ecosystem Experiments (NGEE) project. Her previous projects in the lab has included  oil bioremediation in the Gulf of Mexico and bacteria-algae interactions in Northern California’s Eel River. She began working at Berkeley Lab in 2010 while studying Environmental Earth Science at UC Berkeley.

Bryson Cwick (Student Research Assistant)
Bryson CwickI work primarily on the Ecosystems and Networks Integrated with Genes and Molecular Assemblies (ENIGMA) project.  I work to isolate aerobic and anaerobic bacteria for DNA extraction and sequencing. I also have worked on peatland project (Indonesia), involving methane respiring bacteria.
