The establishment of microbes in the rhizosphere requires a complex sequence of mobility, proliferation, and attachment/detachment from the root as well as soil surfaces. Most research has focused on proliferation and biofilm formation while the mobility and attachment of microbes in soil has remained mysterious and hidden. We combined novel microscopy technologies and mathematical models to capture and characterise the dynamic movement of bacteria through soil during the early stages of root colonisation. The study revealed how bacteria behave as a flock to exploit the pore space and move towards plant roots where they collectively interact with the root tip before forming biofilms on more mature root zones. Results in this study add significantly to our understanding of the biophysical mechanisms enabling microbial colonisation dynamics in soil.
