Rhizosphere in space and time – challenges for designing the most relevant root traits for efficient nutrient acquisition

Résumé

[début du texte]The rhizosphere, i.e. the soil volume that is influenced by the activities of living roots, has been largely documented for its pivotal role in plant nutrition, and thus ecological significance in terrestrial ecosystems (e.g. Hinsinger et al., 2009). The number of studies on the fate of nutrients in the rhizosphere, especially phosphorus amongst major nutrients, iron and zinc amongst micronutrients, has considerably increased over the past decades, as revealed by the published literature. However, much of our understanding of the underlying rhizosphere processes rely on microcosm experiments in more or less artificial conditions. In contrast, we still lack comprehensive studies of the rhizosphere of field-­‐grown plants that includes both its spatial and temporal dimensions. The aim of this keynote lecture is to address these two facets that challenge our capacity to predict plant nutrition and to manipulate such rhizosphere properties for the purpose of an ecological intensification of agroecosystems.
