Persistence Control SFA

Understanding the genetic determinants of environmental persistence, from microbe to community to ecosystem.

The Persistence Control of Engineered Functions in Complex Soil Microbiomes Science Focus Area (PerCon SFA), led by Dr. Robert Egbert at Pacific Northwest National Laboratory (PNNL), seeks to understand plant-microbiome interactions in bioenergy crops to establish plant-growth-promoting microbiomes within the rhizosphere. This vision requires uncovering exudate catabolism pathways from plant roots, eliminating genes that support fitness in bulk soil environments without decreasing rhizosphere fitness, and engineering rhizosphere niche occupation traits in phylogenetically distant bacteria. These efforts aim to increase our understanding of plant-microbe interactions and to extend high-throughput systems and synthetic biology tools to non-model microbes.
