Update on Root Nutrient Foraging Root Nutrient Foraging
During a plant’s lifecycle, the availability of nutrients in the soil is mostly heterogeneous in space and time. Plants are able to adapt to nutrient shortage or localized nutrient availability by altering their root system architecture to efficiently explore soil zones containing the limited nutrient. It has been shown that the deficiency of different nutrients induces root architectural and m...
متن کاملRoot system size and precision in nutrient foraging: responses to spatial pattern of nutrient supply in six herbaceous species
1 An experiment was carried out to test the hypotheses that in heterogeneous environments: (i) the size of species’ root systems will be negatively correlated with their ability to place roots precisely in nutrient-rich patches; (ii) precision of root placement will be less affected by distance to nutrient patches in species with large root systems; (iii) species with greater precision in root ...
متن کاملRoot Foraging Increases Performance of the Clonal Plant Potentilla reptans in Heterogeneous Nutrient Environments
BACKGROUND Plastic root-foraging responses have been widely recognized as an important strategy for plants to explore heterogeneously distributed resources. However, the benefits and costs of root foraging have received little attention. METHODOLOGY/PRINCIPAL FINDINGS In a greenhouse experiment, we grew pairs of connected ramets of 22 genotypes of the stoloniferous plant Potentilla reptans in...
متن کاملRoot morphology and mycorrhizal symbioses together shape nutrient foraging strategies of temperate trees.
Photosynthesis by leaves and acquisition of water and minerals by roots are required for plant growth, which is a key component of many ecosystem functions. Although the role of leaf functional traits in photosynthesis is generally well understood, the relationship of root functional traits to nutrient uptake is not. In particular, predictions of nutrient acquisition strategies from specific ro...
متن کاملLinking root traits to nutrient foraging in arbuscular mycorrhizal trees in a temperate forest.
The identification of plant functional traits that can be linked to ecosystem processes is of wide interest, especially for predicting vegetational responses to climate change. Root diameter of the finest absorptive roots may be one plant trait that has wide significance. Do species with relatively thick absorptive roots forage in nutrient-rich patches differently from species with relatively f...
