Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Eric Hill
We would like to identify the identity and concentration of all organic carbon in this one sample, since we are using this as a feed stock for further experiments.
Lead Institution: Oregon State University
Principal Investigator: Kate Lajtha
Limited knowledge of the molecular mechanisms behind soil organic matter (SOM) stabilization and destabilization processes impedes improving models of earth systems and global carbon dynamics, as well as our ability to understand important linkages...
Lead Institution: University of Vermont
Principal Investigator: Aimee Classen
Soil carbon (C) feedbacks to the atmosphere remain one of the greatest areas of uncertainty in future climate predictions, largely due to an inadequate representation of three key factors in ecosystem models -- soil organic matter (SOM) chemistry,...
Lead Institution: Environmental Molecular Sciences Laboratory
Principal Investigator: Kirsten Hofmockel
Soil organic matter (SOM) is the largest active carbon reservoir in the terrestrial environment and significantly influences soil fertility, water quality, global C cycling and associated feedbacks to Earth's climate system. It is increasingly...
Lead Institution: Lawrence Berkeley National Laboratory
Principal Investigator: Kolby Jardine
Polysaccharides are major components of plant cell walls that can be converted into fuels by microbial fermentation, making plant biomass an important bioenergy resource. However, a substantial fraction of plant cell wall polysaccharides are...
Lead Institution: Pacific Northwest National Laboratory
Principal Investigator: Garry Buchko
A potential consequence of rapid climate change is the emergence of epidemic infectious zoonotic diseases as the habitats of disease carriers change to expose human populations to new infectious agents. These environmental changes, along with the...
Lead Institution: Joint Genome Institute
Principal Investigator: Susannah Tringe
Coastal environments are a source of significant uncertainty in global climate models, and have historically been subjected to large-scale manipulations with substantial impact on the global carbon cycle. The objective of this proposal is to...
Lead Institution: University of Florida
Principal Investigator: Hui-ling Liao
As the critical members of forest microbiome, ectomycorrhizal fungi (EMF) play important roles in forest ecosystems. EMF provide their tree hosts with macro- and micronutrients in exchange for photosynthetically fixed carbon (C) and can catalyze the...
Lead Institution: University of Arizona
Principal Investigator: Malak Tfaily
Interactions at the plant-soil-microbe nexus are difficult to track given the complex networks of species and metabolites involved, in addition to the general challenges to studying heterogeneous and uncontrolled ecosystems. Here, we propose to...
Lead Institution: Donald Danforth Plant Science Center
Principal Investigator: Dilip Shah
Antimicrobial peptides (AMPs) are a major component of innate immunity against infectious diseases in animals and plants [2]. A feature prominent in many families of AMPs, such as defensins (Figure 1), is disulfide covalent crosslinks between pairs...
