  • Northern corn leaf blight genes identified in new study
    on January 12, 2018 at 3:40 am

    Midwestern corn growers know the symptoms of northern corn leaf blight all too well: greenish-gray lesions on the leaves that can add up to major yield losses if not detected and treated early. Corn resistance genes have been identified, but the fungal disease has found ways to sneak around corn's defenses. Now, researchers have discovered how the fungus is outsmarting corn, and they may be able to use this information to help corn fight back. […]

  • Solving Darwin's 'abominable mystery': How flowering plants conquered the world
    on January 11, 2018 at 7:17 pm

    Researchers have found that flowering plants have small cells relative to other major plant groups, made possible by a greatly reduced genome size, and this may explain how they became dominant so rapidly in ecosystems across the world. […]

  • The circadian clock sets the pace of plant growth
    on January 11, 2018 at 7:16 pm

    Researchers have discovered that the members of a protein family from the plant internal clock act sequentially to limit the plant growth until the end of the night. This knowledge could help to understand how plants face different kinds of stress that affect their growth, such as drought or high temperature. […]

  • Unusual plant immune response to bacterial infection characterized
    on January 8, 2018 at 6:02 pm

    When you see brown spots on otherwise healthy green leaves, you may be witnessing a plant's immune response as it tries to keep a bacterial infection from spreading. Some plants are more resistant to such infections than others, and plant biologists want to understand why. Scientists studying a plant protein called SOBER1 recently discovered one mechanism by which, counterintuitively, plants seem to render themselves less resistant to infection. […]

  • Many Midwestern retailers sell mislabeled invasive vines
    on January 8, 2018 at 5:10 pm

    Gardeners hoping to celebrate the beauty of American bittersweet -- a native vine that produces orange berries in the fall and is used for wreaths -- may be unwittingly buying an invasive bittersweet instead. That's because many Midwestern retailers are selling oriental bittersweet with labels misidentifying it as the native plant, researchers report. These sales are occurring in stores and online. […]

  • Less chewing the cud, more greening the fuel
    on January 8, 2018 at 2:02 pm

    Plant biomass contains considerable calorific value but most of it makes up robust cell walls, an unappetizing evolutionary advantage that helped grasses to survive foragers and prosper for more than 60 million years. The trouble is that this robustness still makes them less digestible in the rumen of cows and sheep and difficult to process in bioenergy refineries for ethanol fuel. Until now, with the discovery of a gene that controls that robustness. […]

  • Climate change: Soil animals cannot explain self-reinforcing effect
    on December 21, 2017 at 3:13 pm

    When the soil warms up, it releases more carbon dioxide (CO2) -- an effect that further fuels climate change. Until now, it had been assumed that the reason for this was mainly due to the presence of small soil animals and microorganisms that would eat and breathe more in warmer temperatures. However, a new study has shown that this is not the case. Quite the contrary: If warmth is accompanied by drought, the soil animals eat even less. […]

  • Plant defense following the iron-maiden principle
    on December 20, 2017 at 5:20 pm
