Holz, M; Zarebanadkouki, M; Carminati, A; Hovind, J; Kaestner, A; Spohn, M: Increased water retention in the rhizosphere allows for high phosphatase activity in drying soil, Plant and Soil (2019), doi:10.1007/s11104-019-04234-3
Abstract:
Soil drying negatively impacts several rhizosphere processes, but plant roots are capable of alleviating changes in rhizosphere water content by releasing mucilage. We propose that enhanced 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.
