    Karyotype structure and evolution in Brachypodium annuals

    The Brachypodium (Poacea) genus is a useful model system for studying grass genome organisation. Its key representative B. distachyon is well characterised at the cytogenetic and genomic level, unlike other Brachypodium species such as B. stacei and B. hybridum. Using comparative chromosome mapping with B. distachyon-originated BAC-based probes, Lusinska et al. identify individual chromosomes of […] More

    To find true botanical art, go … North!

    Marianne North: the Kew Collection by Royal Botanic Gardens Kew, 2018. Kew Publishing. The Royal Botanic Gardens at Kew are rightly famed for their living collection of plants from around the globe (and for the world-renowned architecture of the iconic Palm House and recently-restored Temperate House…). However, one of the unsung gems of Kew is […] More

    Phenotypic plasticity in response to temperature fluctuations is genetically variable in Arabidopsis thaliana

    Climate change will not only mean warmer temperatures but also stronger temperature fluctuations. Phenotypic plasticity could help plants to deal with negative effects of temperature variability and allow them to rapidly adjust traits to adverse conditions. Moreover, genetic variation in such plasticity could provide potential for adaptive evolution in response to changing climate variability. In […] More

    Positive and negative interactions on a dioecious grass species performance

    Dioecious plants are of particular concern in view of global environmental changes because reproductive females are more sensitive to abiotic stresses, thus compromising population viability. Positive interactions with other plants may counteract the direct effects of any abiotic environmental stress, allowing them to thrive and maintain a viable population in suboptimal habitats, although this process […] More

    Shoot-based model and laser scanner data to study crown development

    Functional–structural plant models (FSPMs) allow simulation of tree crown development as the sum of modular (e.g. shoot-level) responses triggered by the local environmental conditions. The actual process of space filling by the crowns can be studied. Although the FSPM simulations are at organ scale, the data for their validation have usually been at more aggregated […] More

    Source, Sink, or Both?

    There were many great articles concerning cross-disciplinary research at the interface between plant biology, mathematics and computer science before the launch in silico Plants (isP). We are excited for isP to be home to these types of articles in the future. More

    Limited seed and pollen gene dispersal in Taxus baccata

    Dispersal is crucial due to its direct impact on dynamics of a species’ distribution as well as having a role in shaping adaptive potential through gene flow. In plants forming scarce and small populations, knowledge about the dispersal process is required to assess the potential for colonizing new habitats and connectivity of present and future […] More

    A software package to simulate daily field crop canopy photosynthesis

    How can we improve crops in the future? One method would be to improve the photosynthesis process in crops, to increase productivity from the same plants. However, there isn’t a lot of research connecting leaf-level photosynthetic manipulation and crop performance. A new software package developed by Wu et al. produces a model of diurnal crop […] More

    A new methodology to simplify the recalibration of FSP models

    Functional–structural plant models (FSPM) define the interactions between the plants and their environment at organ to plant scale. However, the high level of description of the structure or model mechanisms makes this type of model very complex and hard to calibrate. Mathieu et al. propose a two-step method to facilitate the calibration process based on […] More

    Sodium chloride alters cadmium accumulation and metabolites in halophyte Carpobrotus rossii

    Salinity affects plant growth and metabolites in plants, which in turn affect Cd accumulation. Cheng et al. ran a hydroponic experiment to assess the effect of NaCl on the metabolic response to Cd and Cd accumulation in the halophytic Cd-accumulator Carpobrotus rossii (Aizoaceae). They find NaCl decreased Cd accumulation in the shoot by decreasing Cd […] More
