    Phosphorus and elevated CO2 enhance drought tolerance

    Benefits to crop productivity arising from increasing CO2 fertilization may be offset by detrimental effects of global climate change, such as an increasing frequency of drought. Phosphorus ( P ) nutrition plays an important role in crop responses to water stress, but how elevated CO2 (eCO2) and P nutrition interact, especially in legumes, is unclear. […] More

    Molecular analysis and evolution of forisomes

    Forisomes are specialized structural phloem proteins that mediate sieve element occlusion after wounding exclusively in papilionoid legumes, but most studies of their structure and function have focused on the Old World clade rather than the early lineages. Müller et al. combine sequence analysis and bioinformatics with structural and functional analysis of native forisomes and artificial forisome-like […] More

    Turbid medium models and light in intercropping

    Light partitioning within intercropping systems is mostly modelled by using the turbid medium analogy. Barillot et al. assess this approach by comparing it with a light-projective model based on 3-D plant mock-ups for contrasting grass–legume canopies (wheat–pea, tall fescue–alfalfa, tall fescue–clover). They find that light partitioning is accurately predicted by the turbid medium approach in most […] More
