Tóm tắt

The objective of this project was to develop a multifunctional in situ platform to link gene expression, regulation, and function with the spatiotemporal context of the whole cell environment. In particular, we focus on a synthetic rhizosphere microhabitat and spatial regulation of genes encoding production of exopolysaccharides, or EPS. We have fully met this objective and report results that support the hypothesis: microbial EPS production, acting at pore throats, limits water evaporation and promotes resilience of terrestrial soil systems.
