    Wood (aka ‘the really hard stuff inside trees’) is as ancient a building material and engineering solution as they come, but new uses are still being found for timber in the most unlikely of applications. Take for instance wind- and water-powered turbines. Loved and hated in equal measure, they are often proposed as an environmentally […] More

    Spring temperatures affect season-long growth in grapevine

    Plant growth is commonly understood to be determined by current temperature. Using a free-air cooling and heating system in the field, Keller and Tarara (pp. 131–141) show that much of the seasonal variation in shoot growth, shoot architecture and leaf-area development in Vitis vinifera may be introduced by bud-level differences in temperature around the time […] More

    Unification of Pennisetum, Cenchrus and Odontelytrum

    Unification of Pennisetum, Cenchrus and Odontelytrum Based on a plastid, morphological and nuclear phylogeny, Chemisquy et al. (pp. 107–130) show that the genera Pennisetum, Cenchrus and Odontelytrum form a monophyletic group with high support. The nuclear phylogenetic analysis reveals a reticulate pattern of relationships among Pennisetum and Cenchrus. Consequently, the species of Pennisetum and Odontelytrum […] More
