Phene interactions determine nutrient capture in common bean
Rangarajan et al. employ the functional–structural model SimRoot to explore how interactions among architectural phenes in common bean, Phaseolus vulgaris (Fabaceae) determine the acquisition of phosphate and nitrate...

Hydraulic conductivity of roots
Radial and axial hydraulic conductivities are key parameters for understanding and modelling root water uptake. Despite their importance, there is limited experimental information relating to how the radial and axial...

Aminotransferases provide the signals for root growth
Uncovering the role of new aminotransferases in the regulation of the signals behind root growth, Le Deunff et al. show that L-aminoethoxyvinylglycine (AVG) acts as an ethylene and auxin biosynthesis inhibitor. AVG is...
Maize root growth angles, nitrogen capture and environmental conditions
Crops capable of improved nitrogen capture are in demand for the purposes of efficient global agricultural production. Dathe et al. employ functional-structural modelling to test the hypothesis that variation in the...
Crop acquisition of phosphorus, iron and zinc in intercropping (Review)
Phosphorus (P), iron (Fe) and zinc (Zn) are essential elements for plant growth and development but their availability in soil is often limited. Xue et al. review the processes regulating the acquisition of these...
Root foraging and yield in maize/bean/squash polycultures
One cause of the yield advantage in the 'three sisters' polyculture is that the crops have different, possibly complementary, root foraging strategies.
Limited plasticity in functional root traits of maple and oak
Traits affecting the form and function of fine roots in woody plants show complex phenotypic variation. Lee et al. manipulate root segments of 2-year-old Acer rubrum and Quercus rubra seedlings in order to compare...
Basal root whorl number and P acquisition
BRWN is associated with increased phosphorus acquisition and this may have value for selection of genotypes with better performance in low-phosphorus soils.
Modelling root development with signalling control (PMA Special Issue)
Modelling root development with signalling control There are two major challenges for using functional–structural modelling to study autoregulation of nodulation: reconstruction of legume root architecture and co...
