    Plant cell biology in the frame!

    Notwithstanding the centuries we’ve spent peering at, poking, prodding and penetrating the inner workings of plant cells with various types of microscopes and decades undertaking investigations at the sub-cellular level, there are still new discoveries to be made. Here are two, united by the theme of cell–cell transport. First, the recent revelation by Deborah Barton […] More

    Functional significance of style length in Mertensia

    Mertensia fusiformis (Boraginaceae) is a spring-flowering perennial showing pronounced intraspecific variation in style length and stigma–anther separation. Forrest et al. show that population-level variation in flowering time, driven by patchiness in timing of snowmelt, causes different populations to experience different temperature regimes during flowering and functionally distinct suites of pollinators. The interaction between plant and […] More

    Botany: A Blooming History

    Last night at 9pm hell froze over – the BBC broadcast a programme about plant taxonomy on a mainstream TV network. Did you see it? I thought not, it was tucked away on BBC4. It was excellent and well worth watching – available for UK viewers on the BBC iPlayer. This is the way we […] More

    Plants on the prowl

    Plants are not noted for their dynamic lifestyles. Indeed, rooted in the soil as they tend to be, they are usually written off as little more than ‘stick in the muds’. But their sedentary lifestyle is not always so sedentary; plants can travel great distances. With the obvious exception of tumbleweeds, plants are adept at […] More

    Turnover of foliar N absorbed at different times

    Although nitrogen turnover within plants has been studied intensively, the fate of N absorbed at different times and particularly over winter is not completely understood. Ueda et al. trace N absorbed at different times of the year in a temperate deciduous oak, Quercus serrata, and find that N absorbed in winter and in the previous […] More

    ERECTA gene and leaf cellular development

    <i>ERECTA</i> gene and leaf cellular development The ERECTA gene plays a role in the balance between epidermal cell expansion and division in leaves. Tisné et al. perform spatial and temporal analyses of these processes in successive developing leaves of Arabidopsis thaliana in ERECTA and erecta lines in comparison with LER and Ler lines, and find […] More

    Early summer and the hedgerows: elderflower champagne

    Early summer brings the elderflower (Sambucus nigra, either a variable species or a species complex) into flower in hedgerows, woodland openings and waste ground throughout Europe. The flowers have a unique sweet smell, and making elderflower champagne, a non-alcoholic sparkling lemonade-type drink, is one of the pleasures of what is the first (and sometimes last) […] More

    Cultivation and domestication of wild pea

    Wild pea seed dormancy is mediated by a water-impermeable seed coat. Using wild and domesticated pea (Pisum elatius, P. humile and P. fulvum), Abbo et al. show that the agronomic implications of wild pea hard-seededness are incompatible with millennia of unconscious selection leading to domestication: poor establishment and associated net yield loss in cultivation is […] More

    Say it with… fungi?

    I’ve often thought it must be great to be remembered in a scientific binomial (but, as a botanist, it has to be a suitable plant): for most of us that is probably the closest to immortality that we can probably achieve. But I can only imagine what Alfred ‘Ernie’ Schuyler – noted botanist and Emeritus […] More
