One-of-a-kind experiment tracks plant evolution in response to climate change at 30 sites worldwide
For decades, ever since biologists recognized the potential environmental harms from climate change, they have worried that plants will not be able to evolve fast enough to adapt to a rapidly warming planet. But the pace of research to understand how species respond has been slow, typically based on single, stand-alone experiments by isolated research groups around the world.
The common thale cress (Arabidopsis thaliana), an unassuming plant with tiny white flowers, has become the subject of one of the most ambitious biological experiments in recent years. An international team of scientists spent five years tracking the plant's evolution at 30 sites scattered around the world, from the cool mountainous regions of Europe to the hot deserts of North America and the Middle East. The results of this study, published in …
In a unique international experiment involving biologists in Europe, the Middle East and the United States, hundreds of small plots of Arabidopsis, the reference laboratory plant, have been sown in a variety of climates, ranging from the alpine mountains of the Lautaret Garden (UGA/CNRS) to the deserts. Scientists have allowed them to evolve for three years.
Madrid.- Plants have demonstrated an amazing ability to evolve genetically and adapt to climate change, but they have red lines, and scientists have found in extreme heat the limit that exceeds their defense mechanisms, breaks their ability to adapt and condemns populations to extinction.
