A plant’s development is strongly linked to the water and carbon (C) flows in the soil-plant-atmosphere continuum.Ongoing climate shifts will alter the water and C cycles and affect plant phenotypes. Comprehensive models that simulatemechanistically and dynamically the feedback loops between water and C fluxes in the soil-plant system are useful toolsto evaluate the sustainability of genotype-environment-management combinations that do not yet exist.

Plant roots create chemical gradients within the rhizosphere, but little information exists onthe effect of root properties on the distribution of chemical gradients. The research aim was toanalyse and model the effects of root type and age, radial root geometry and root hairs onnutrient gradients in the rhizosphere. [...]

Background and AimsThe advantages of genotype mixtures on soil water balance are still poorly understood. We aim todetermine the impact of soil water conditions (well-watered or chronic water defi cit) on the root wateruptake (RWU) of two contrasting root genotypes and their mixture at the booting stage.MethodsWe conducted a controlled plant-soil column experiment and quantifi ed daily vertical profi les of thefraction of RWU (fRWU, % cm− 1), i.e. [...]

In this work, we couple the functional–structural plant model CPlantBox to the Unreal Engine by exploiting the implemented raytracing pipeline to evaluate light influx on the plant surface. There are many approaches for photosynthesis computation and light evaluation, though they typically are limited by versatility, compute speed, or operate on much coarser resolutions. [...]
