Abstract

Mucilage secreted by roots and EPS produced by microorganisms alter the physical propertiesof the soil solution and impact the water dynamics in the rhizosphere. The high viscosity of mucilageand EPS is responsible for the formation of thin filaments and interconnected thin lamellaethat span throughout the soil matrix maintaining the continuity of the liquid phase across the porespace even during severe drying. The impact of these mechanisms on plant and microorganismsneeds to be explored.
