Multi-imaging approach to study the root–soil interface
Combining neutron and fluorescence imaging allows study of the spatiotemporal patterns of oxygen, pH and water content distribution in lupin rhizospheres.
Increased competitive ability in an invasive plant
A study of the invasive plant Lythrum salicaria distinguishes between competitive effects and responses of invasive and native plants.
Biogeography of circumboreal taxa of Pyrola
A study finds that three circumboreal lineages of Pyrola have arisen independently, and at least two of these appear to have originated in Asia.
Cryptic refugia of Cryptomeria japonica in last glacial maximum
A combination of phylogeography and species distribution modelling methods identify the responses of Cryptomeria japonica, to past climatic changes.
Evolution of genome size and chromosome numbers in Genlisea
Measurements of nuclear genome sizes from cultivated plant material for a comprehensive taxon sampling that includes nearly half of all species in Genlisea.
Diversification and evolution of dispersal ability in Brassiceae
Increased dispersal ability in Brassiceae can influence macro-evolutionary processes, possibly by increasing the propensity for long-distance dispersal.
Buzz pollination, floral traits and pollen release
Bumble-bee workers assort themselves among Pedicularis species according to size, adjusting their buzzing behavior in relation to the species’ floral traits
Fruit removal increases root zone respiration in cucumber
Kläring et al. find that removing all fruit from the cucumber plant results in a doubling of the root-zone respiration within a few hours.
Stress tolerance of recalcitrant embryonic axes of Quercus
A study finds that four Quercus species adapted to arid and semi-humid climates still produce recalcitrant seeds.
Root foraging and yield in maize/bean/squash polycultures
One cause of the yield advantage in the ‘three sisters’ polyculture is that the crops have different, possibly complementary, root foraging strategies.
