  • Some plants grow bigger -- and 'meaner' -- when clipped, study finds
    on October 11, 2017 at 4:03 pm

    Some plants behave like the mythical monster Hydra: Cut off their heads and they grow back, bigger and better than before. A new study finds that these 'overcompensators,' as they are called, also augment their defensive chemistry -- think plant venom -- when they are clipped. The discovery could lead to the development of new methods for boosting plant growth while reducing the need for insecticides, the researchers said. […]

  • Removing invasive plants can increase biodiversity in stream waters
    on October 11, 2017 at 1:17 pm

    Restoration projects to remove invasive plants can make a positive impact on native plant species. But a new study shows restoration has an additional benefit. Removal of invasive species growing alongside a stream or river can also improve the biodiversity of aquatic organisms. […]

  • Protein restricts sap uptake by aphids
    on October 10, 2017 at 5:02 pm

    Researchers have discovered how plants can defend themselves against aphids. They recorded aphid behavior on video, and identified a plant protein that keeps aphids from feeding. […]

  • Mass extinctions led to low species diversity, dinosaur rule
    on October 10, 2017 at 4:40 pm

    Two of Earth's five mass extinction events -- times when more than half of the world's species died -- resulted in the survival of a low number of so-called 'weedy' species that spread their sameness across the world as the Earth recovered from these dramatic upheavals. The findings could shed light on modern high extinction rates and how biological communities may change in the future. […]

  • Breeding salt-tolerant plants
    on October 10, 2017 at 4:40 pm

    The quinoa plant might serve as a model for making other crops salt-tolerant. It grows well on saline soils because the excess salt is simply dumped into special bladders on its leaves. […]

  • Deer prefer native plants leaving lasting damage on forests
    on October 6, 2017 at 6:21 pm

    When rampant white-tailed deer graze in forests, they prefer to eat native plants over certain unpalatable invasive plants, such as garlic mustard and Japanese stiltgrass. These eating habits lower native plant diversity and abundance, while increasing the proportion of plant communities made up of non-native species, according to a new study. […]

  • Plant cells survive but stop dividing upon DNA damage
    on October 6, 2017 at 2:18 pm

    The cell cycle is how a cell passes its DNA but ceases if the DNA is damaged, as otherwise it risks passing this damage to daughter cells. Scientists report a new molecular mechanism that explains how this cessation occurs. The study shows that the transcription factor family MYB3R is normally degraded, but accumulates upon DNA damage to prevent cell cycle progression. […]

  • Key plant species may be important for supporting wildflower pollinators
    on October 5, 2017 at 6:17 pm

    Increased agricultural production has likely led to loss, fragmentation, and degradation of flower-rich habitats for pollinators. To counteract these negative effects of modern agricultural practices, efforts to maintain and restore diverse plants in agricultural landscapes -- called agri-environmental schemes -- have been implemented in numerous European countries. […]

  • World's botanic gardens contain a third of all known plant species, and help protect the most...
    on September 25, 2017 at 3:13 pm

    The most in-depth species survey to date finds an 'astonishing array' of plant diversity in the global botanic garden network, including 41 percent of all endangered species. However, researchers find a significant imbalance between tropical and temperate plants, and say even more capacity should be given to conservation, as there is 'no technical reason for plant species to become extinct.' […]

  • With extra sugar, leaves get fat too
    on September 25, 2017 at 2:47 pm

    Eat too much without exercising and you'll probably put on a few pounds. As it turns out, plant leaves do something similar. A new study shows that retaining sugars in plant leaves can make them get fat too. In plants, this extra fat accumulation could be a good thing. It could help turn plants into factories for making biofuels and other useful chemicals. […]
