Abstract in another language

Soil drying negatively impactsseveral rhizosphere processes, but plant roots are capable of alleviating changes in rhizosphere water content by releasing mucilage. We propose thatenhanced water retention in the rhizosphere due to mucilage and microbial extracellular polysaccharides allows for fast diffusion of enzymes and substrates, and thus high enzyme activity in the vicinity of roots.
