Researchers at the U.S. Department of Energy's Pacific Northwest National Laboratory and Kansas State University found that soil drying significantly affected the structure and function of soil microbial communities.

A warming Earth is predicted to result in increased drought extent and intensity in the highly fertile and productive grasslands of the central United States. These soils store large reserves of carbon. The decrease in soil moisture due to drought has largely unknown consequences on soil carbon cycling and other key biogeochemical cycles carried out by soil microbiomes. Researchers at the U.S. Department of Energy's Pacific Northwest National Laboratory and Kansas State University found that soil drying significantly affected the structure and function of soil microbial communities. This included shifts in expression of specific metabolic pathways, such as those leading toward the production of compounds that build up within cells to keep microbes alive during drought.

Study - Application - Approach - Details - Soil

This study demonstrates the application of a multi-omics approach to decipher details of the soil microbial community's metaphenomic response to environmental change. The approach should apply to studies of other complex microbial systems as well. This research supports the genomic science mission by revealing fundamental principles that guide the interpretation of the genetic code into functional proteins, metabolic pathways, and the metabolic/regulatory networks underlying the systems biology of microbial communities. Advancing fundamental knowledge of these systems will enable understanding of the role of biological systems in the environment and how environmental change affects soil microbial communities.
