The responses of plants to non-uniform supplies of nutrients.

- 1 August 1994
When the root system of a nutrient deficient plant is supplied locally with the nutrient, the roots grow and proliferate in the nutrient-rich zone, sometimes spectacularly so. In addition, uptake per… Expand
Plant root proliferation in nitrogen–rich patches confers competitive advantage

Plants respond strongly to environmental heterogeneity, particularly below ground, where spectacular root proliferations in nutrient–rich patches may occur. Such ‘foraging’ responses apparently… Expand
Plant roots release phospholipid surfactants that modify the physical and chemical properties of soil.

• Plant root mucilages contain powerful surfactants that will alter the interaction of soil solids with water and ions, and the rates of microbial processes. • The lipid composition of maize, lupin… Expand
Why plants bother: root proliferation results in increased nitrogen capture from an organic patch when two grasses compete
We investigated whether the capacities of Lolium perenne L. and Poa pratensis L. roots to proliferate locally and to alter local nitrogen (N) inflows in a decomposing organic matter patch were… Expand
What limits nitrate uptake from soil
An accepted view, that unless nitrate concentrations in the soil solution are very low (e.g. below 0.1−0.2 mol m −3 ) the growth of high-yielding crops is not limited by the availability of nitrogen,… Expand
Molecular defect in combined beta-galactosidase and neuraminidase deficiency in man.

In normal human fibroblasts, an enzymically active 85,000-dalton precursor form of beta-galactosidase is processed, via a number of intermediates, into a mature 64,000-dalton form. In addition there… Expand
Root proliferation, soil fauna and plant nitrogen capture from nutrient‐rich patches in soil
We investigated interactions between plant roots, protozoa and nematodes after addition of patches containing inorganic or organic nitrogen in order to determine whether root proliferation could… Expand
Carbon transfer between plants and its control in networks of arbuscular mycorrhizas
1. Two studies using the stable-isotope 13C have shown that large amounts of carbon can move between plants linked by arbuscular mycorrhizal fungi. Quantities comparable to the carbon cost of the… Expand
Competition between roots and soil micro‐organisms for nutrients from nitrogen‐rich patches of varying complexity
Summary 1 We used Lolium perenne plants grown in microcosms to investigate the responses of root demography, plant N capture, soil fauna populations and microbial community profiles to five… Expand
Spatial and physical heterogeneity of N supply from soil does not influence N capture by two grass species.
1. Plant responses after addition of nitrogen-rich complex organic material (Lolium perenne L. shoots), differing in physical (coarsely cut or finely ground) and spatial (uniform dispersion or… Expand
