Adaptive Strategies of Bradyrhizobium
Soil microbial communities are among the richest sources of biodiversity on Earth. However, very little is known about the roles of individual microbial populations living in soil and how they affect important processes such as soil fertility and carbon cycling. This proposal investigates free-living Bradyrhizobium, an abundant and widespread soil bacterium, and will provide mechanistic… [Read More]
Virus and Microbial Effects on Ocean Nutrient Cycling
Collected at the Southern Ocean Time Series, transcriptomes and manipulative experiments will establish virus and microbial processes that constrain the carbon cycle and system biogeochemistry (major DOE mission areas). Interactions on sinking particles, the specificity of virus-host relationships and trace metal effects will be examined. The cumulative data set will allow for the development of… [Read More]
Regulating Water Use Efficiency Traits
Roots and stomata are plants’ primary entry and exit points for water. Therefore, they are key targets for manipulation to improve bioenergy crop productivity, resilience and sustainability by reducing the risk of crop losses due to inadequate water supply. The number of pores, called stomata, on the leaf surface influences how much water the crop… [Read More]
Time-Series of Freshwater Lake Microbial Communities
Freshwater lakes contain diverse and dynamic microbial communities that play key roles in maintaining water quality, cycling nutrients, and regulating carbon uptake and storage. They are important hotspots for biogeochemical cycling in terrestrial landscapes. This project aims to use hundreds of samples collected over time in two very different lakes to understand how these communities… [Read More]
