Temporal dynamics and genetic diversity of chemotactic-competent microbial populations in the rhizosphere.

Abstract excerpt

The contribution of chemotaxis to the competitive colonization of the rhizosphere for the vast majority of the soil community is unknown. We have developed and applied a molecular diagnostic tool, based on a gene encoding the central regulator of bacterial chemotaxis (cheA), to characterize and temporally track specific populations of native microbes with chemotaxis potential that are present in soil exposed to...
