    Towards turgor-driven growth in FSPs

    In many scenarios, water availability plays a determinant role in plant growth. Current functional-structural plant models (FSPs) mainly focus on plant-carbon relations and largely disregard the importance of plant-water relations. Coussement et al. adapted an existing water-flow and a storage model was made was for integration into FSPs. It applies explanatory concepts of water flow, […] More

    GrapevineXL: a model coupling plant water transport and leaf gas exchange

    Quantifying the response of plant water status to environmental conditions and its effect on carbon acquisition are essential for simulating plant growth and fruit composition, especially in the context of climate change. Zhu et al. present GrapevineXL, a functional-structural grapevine model that couples the dynamics of water transport from soil to leaf with gas exchange […] More

    Modelling temporal variation of parameters used in photosynthesis models

    Several studies have found seasonal and temporal variability in leaf photosynthesis parameters in different crops. Poirier-Pocovi et al. use six-year-old fruit-bearing branches of ten-year-old apple trees to study and model the seasonal variation of photosynthetic parameters in leaves of vegetative shoots, as a function of global fruit load (at the branch level), with and without […] More

    The Fungal Kingdom, edited by Joseph Heitman, Barbara J. Howlett, Pedro W. Crous, Eva H. Stukenbrock, Timothy Y. James and Neil A. R. Gow, 2018. American Society for Microbiology Press There has been a veritable mushrooming of fungus books of late (e.g. the trio from Nicholas Money – Fungi: A Very Short Introduction (2016), Mushrooms: […] More

    Evolution of mating system, life history, and photosynthetic physiology in Clarkia

    In the western United States, Clarkia (Onagraceae) taxa vary in mating system, life history, and photosynthetic physiology. Self-fertilizing taxa bloom earlier in the year and have higher rates of photosynthesis than their most closely related cross-pollinating species. By performing a multi-generational artificial selection experiment, Emms et al. find evidence that these traits evolved independently of […] More

  • The reconstructed three-dimensional root system architecture models for individual maize plants at the grain-filling stage of two cultivars, ZD958 and XY335, with contrasting axile root angles

    Optimizing soil-coring strategies using 3D root architecture models

    Virtual assessment based on root system architecture (RSA) modelling has great value in the optimisation of core-sampling strategies. Based on the measurement dataset of two maize cultivars having contrasting axile root angles, Wu et al. construct contrasting three-dimensional RSA models of individual maize plants in which the different lateral rooting angles are represented. The accuracies […] More

    Biomineralization in the Trichomes of Boraginales

    Boraginales are typically characterized by a dense cover of stiff, mineralized trichomes, likely providing protection against herbivores. These trichomes have long been known to be mineralized with silica. Mustafa et al. investigate detailed biomineralization patterns in representative species from nine families of the order Boraginales by using cryo-SEM and EDX element analysis. Three zones (tip, […] More

    High light aggravates functional limitations of photosynthesis

    Experimental results of salinity effects on cucumber (Cucumis sativus, Cucurbitaceae) can be interpreted with the help of a functional-structural plant (FSP) model. Chen et al. use this novel approach to quantify different salinity effects on canopy photosynthesis and discover interactions between plant architecture, stomatal regulation and light conditions. Salinity effects on plant architecture and photosynthetic […] More

    Introducing The Global Flora

    At Cuttings HQ we love a new botany journal – even if it’s technically described as a serial. So, we were really pleased to find out about The Global Flora, whose first issue was launched in January 2018. Published by Plant Gateway Ltd, this new publishing initiative is intended as a “practical flora to vascular […] More

    Effect of aperture number on pollen performance in Arabidopsis thaliana

    Triaperturate pollen is the most conspicuous synapomorphy of the highly successful eudicot clade. It was previously suggested that this pollen morphology represents the major evolutionary adaptation, and that the stasis of triaperturate pollen is likely the result of selective advantage provided by this morphology. Arabidopsis mutants producing pollen with different aperture numbers allows Albert et […] More

    The Pipe Model Theory half a century on

    Lehnebach et al. review the diverse and multi-disciplinary uses of the Pipe Model Theory (PMT) and associated properties, and scrutinize their validity in the light of current anatomical and physiological knowledge. They discuss applications and modifications of the PMT theory in the context of biomass allocation and hydraulic models, with a particular focus on its […] More
