  • Labellar micromorphology of Zygopetalinae

    Labellar micromorphology of Zygopetalinae

    Molecular evidence indicates that the orchid subtribe Zygopetalinae is sister to Maxillariinae. Davies and Stpiczyńska show that the labellar micromorphology of Zygopetalinae is less diverse than that of Maxillariinae sensu stricto and does not reflect the currently accepted phylogeny based on molecular studies. Instead, the relatively conservative labellar micromorphology of Zygopetalinae spp. is probably due […] More

  • Floral development in Anaxagorea (Annonaceae)

    Floral development in Anaxagorea (Annonaceae)

    Anaxagorea is the phylogenetically basal-most genus in the large, tropical magnoliid family Annonaceae (custard apple). Endress and Armstrong  study floral development for the first time in the genus and show complex whorled floral phyllotaxis, with double organ positions in the outer androecium whorl resulting in a switch from trimery to hexamery and completely plicate carpels. The floral […] More

    Food for the billions – botany has the answers #bad11

    Not only do the growing billions of people in the world want to eat, but those in poorer countries want to share in the lifestyles those of us enjoy in the West. They don’t want to be wondering where the next meal for themselves and their families will be coming from; they don’t want to get ill from eating that meal; they don’t want to spend all their waking hours bent double under the sun weeding their crops; they want to be able to buy and enjoy non-food comforts More

    On our Scoop It between October 9th and October 16th

    These are links from our Scoop It page between October 9th and October 16th: Trees ‘boost African crop yields’ Planting trees that improve soil quality can help boost crop yields for African farmers and improve food security, an assessment shows.   The results appear in the International Journal of Agricultural Sustainability.

  • Cucumbers and melons in medieval manuscripts

    The fashionably late arrival of cucumbers in Europe #bad11

    You might put together a salad from what you’ve grown in your back garden, but it’s a surprisingly cosmopolitan meal. Tomatoes came from Mesoamerica and if you have potato salad, then you have the Incas of South American to thank. Recent research by Jules Janick and Harry Paris, Medieval Herbal Iconography and Lexicography of Cucumis […] More

  • Leaf traits, growth allometry and competition

    Leaf traits, growth allometry and competition

    The ability to simulate plant competition accurately is essential for plant functional-type (PFT)-based models used in climate-change studies. Yu and Gao investigate competition between oak (Quercus liaotungensis) and birch/poplar (Betula platyphylla/Populus davidiana) in a temperate forest using a PFT-based ecosystem model and determine that higher assimilation rates of birch/popular lead to its dominance during early […] More

  • Yellow Stripe-Like metal transporters in Brachypodium

    Yellow Stripe-Like metal transporters in Brachypodium

    The Yellow Stripe-Like (YSL) family of proteins are transporters of metal-phytosiderophore and metal-nicotianamine complexes. Information concerning their physiological role(s) is critical for understanding metal homeostasis on the whole-plant level. By comparative genomics analysis of the YSL family from Brachypodium distachyon, maize and rice, Yordem et al. establish the existence of a highly conserved clade within […] More

    Miscanthus – A bioenergy crop for all seasons – Feature – BBSRC/RuSource

    Via – AnnBotAlan Spedding, Rusource Briefing 1381: Miscanthus breeding Researchers at the Institute of Biological, Environmental and Rural Sciences (IBERS) at the University of Aberystwyth have been undertaking a large-scale study of Miscanthus to provide improved varieties for energy production. One way is to grow varieties which flower at just the right time and […] More

  • Smoking out weeds with karrikinolide

    Smoking out weeds with karrikinolide

    Karrikinolide (KAR1) is a smoke-derived chemical that can trigger seeds to germinate, and shows promise as a tool for flushing out weed seeds from the soil seed bank. Long et al. demonstrate that weeds of Brassicaceae are particularly responsive to KAR1, and that  these responses are complex and transient: light and temperature conditions, dormancy state and seed lot […] More
