Temperature Effects on Metabolite-Mediated Autotroph-Heterotroph Carbon Transfer

ABSTRACT: Much of the bacterial secondary production in the aquatic ecosystems is supported by rapid uptake of labile metabolites released from phytoplankton, either directly through excretion and diffusion or indirectly through lysis and predation. This project seeks to investigate the effects of temperature stress on the metabolite pools produced and released by three model phytoplankton species (a diatom, a coccolithophore, and a cyanobacterium) that will assess changes in the composition and fate of metabolites transferredto bacteria. While focused on estuarine microbes, findings of this project will be broadly relevant to temperature effects on microbial autotrophic-heterotrophic metabolite transfer in freshwater, marine, and soil ecosystems. The work (proposal:https://doi.org/10.46936/10.25585/60001361) conducted by the U.S. Department of Energy Joint Genome Institute (https://ror.org/04xm1d337), a DOE Office of Science User Facility, is supported by the Office of Science of the U.S. Department of Energy operated under Contract No. DE-AC02-05CH11231.

Quantifying the ecophysiology of growing microbes responding to warming along a productivity gradient of the Marr Ice Piedmont Glacier, West Antarctic Peninsula

Project description:Our overarching goal is to understand how microbes along a glacier forefield chronosequence and productivity gradient interact with their environment, how this influences carbon and nitrogen cycling, and how the microbes respond to temperature increases. Specifically, using the novel approach of quantitative SIP paired with metagenomic sequencing, we will calculate growth rates for targeted functional genes and metagenome assembled genomes, quantifying their ecophysiology, in situ. And when paired with gene expression using metatranscriptomic libraries and metabolite production, we will gain a clearer understanding of how microbes grow, how they cycle carbon and nitrogen and how their metabolic activity changes in response to warming.

Project description:The goal of this study is to use both "targeted" and "untargeted" metabolomics to elucidate metabolism of Clostrial and Streptomyces species for biofuel production and plant growth promotion, respectively. For these species, we aim to improve the curation of genome-scale metabolic networks and elucidate their novel secondary metabolism to make secondary metabolites whose identities are waiting to be discovered.
