Floods and droughts are increasingly in the news, and climate experts say their frequency will only go up in the future. As such, it is crucial for scientists to learn more about how these extreme events affect plants in order to prepare for and combat the risks to food security that could result. Like animals, plants have hormones that send chemical signals between its cells relaying information about the plant's development or interactions with the outside world. One particular way in...

Study of plant hormone could have far-reaching implications for cell biology and disease research A recent Van Andel Research Institute (VARI) study published in the journal Science investigating the molecular structure and function of an essential plant hormone could profoundly change our understanding of a key cell process, and might ultimately lead to the development of new drugs for a variety of diseases. The study builds on earlier work by the same team of investigators at VARI...

UC Riverside discovery creates new blueprint for engineering drought tolerant crops. When a plant encounters drought, it does its best to cope with this stress by activating a set of protein molecules called receptors. These receptors, once activated, turn on processes that help the plant survive the stress. A team of plant cell biologists has discovered how to rewire this cellular machinery to heighten the plants' stress response — a finding that can be used to engineer crops to...

Dormant seeds in the soil detect and respond to seasonal changes in soil temperature by changing their sensitivity to plant hormones, new research by the University of Warwick has found. This sensitivity alters the depth of dormancy, indicating to the seed when it is the right time of year to germinate and grow. The seeds of common weeds can survive in the soil in a dormant state for years, in some cases decades, spelling issues for food security when they emerge to compete with crops....

Controlling water loss is an important ability for modern land plants as it helps them thrive in changing environments. New research from the University of Bristol, published today in the journal Current Biology, shows that water conserving innovations occurred very early in plants' evolutionary history. The research focused on the role of stomata, microscopic pores in the surface of leaves that allow carbon dioxide gas to be taken up for use in photosynthesis, while at the same time allowing...

Working to develop heartier, better-adapted crops for southern U.S. Dr. Daniel Leskovar, a Texas AgriLife Research plant physiologist at the Texas AgriLife Research and Extension Center in Uvalde, has been investigating ways to help vegetable plants make a less stressful transition from the greenhouse to the field. "This research can aid in the successful production and possibly even the further profitability of some vegetable crops by producing high-quality, more adaptive plants that will...

GRAND RAPIDS, Mich., Dec. 3 /PRNewswire/ -- Van Andel Research Institute (VARI) researchers have determined precisely how the plant hormone abscisic acid (ABA) works at the molecular level to help plants respond to environmental stresses such as drought and cold. Their findings, published in the journal Nature, could help engineer crops that thrive in harsh environments around the world and combat global food shortages. The findings could also have implications for stress disorders in...

Junior professor's breakthrough launches unprecedented number of publications in high-profile journals Breakthrough research done earlier this year by a plant cell biologist at the University of California, Riverside has greatly accelerated scientists' knowledge on how plants and crops can survive difficult environmental conditions such as drought. Working on abscisic acid (ABA), a stress hormone produced naturally by plants, Sean Cutler's laboratory showed in April 2009 how ABA helps plants...

Structural study at EMBL reveals how plants respond to water shortages Much as adrenaline coursing through our veins drives our body's reactions to stress, the plant hormone abscisic acid (ABA) is behind plants' responses to stressful situations such as drought, but how it does so has been a mystery for years. Scientists at the European Molecular Biology Laboratory (EMBL) in Grenoble, France, and the Consejo Superior de Investigaciones Cientificas (CSIC) in Valencia, Spain discovered that the...

New structure shows how hormone-sensing protein helps plants survive dry spells A team of biologists in California led by researchers at The Scripps Research Institute and the University of California (UC), San Diego has solved the structure of a critical molecule that helps plants survive during droughts. Understanding the inner workings of this molecule may help scientists design new ways to protect crops against prolonged dry periods, potentially improving crop yields worldwide, aiding...
