Manipulating RNA can allow plants to yield dramatically more crops, as well as increasing drought tolerance, announced a group of scientists recently.

A new study shows that duplication events have been vitally important throughout the evolutionary history of gymnosperms, a diverse group of seed plants that includes pines, cypresses, sequoias, ginkgos and cycads. The research indicates that a genome duplication in the ancestor of modern gymnosperms might have directly contributed to the origin of the group over 350 million years ago.
As temperatures rise, the risk of devastating forest fires is increasing. Researchers are using artificial intelligence to estimate the long-term impact that an increased number of forest fires will have on forest ecosystems. Their simulations show how Yellowstone National Park in the USA could change by the end of the century.
A new study sheds light on how plants respond to stressful environmental conditions presented by climate change. Researchers showed that plants grown in drier conditions simulating the effects of climate change exhibited higher costs of reproduction than those grown under current conditions. The findings offer clues about how plant populations might respond to climate change and could provide guidance for developing conservation strategies.
Plant researchers have a potent new tool at disposal: Ia research team shows how to close the stomata of leaves using light pulses.
A research team has investigated how people in five different countries react to various usages of genome editing in agriculture. The researchers looked at which uses are accepted and how the risks and benefits of the new breeding technologies are rated by people.
As the world continues to warm, many arid regions that already have marginal conditions for agriculture will be increasingly under stress, potentially leading to severe food shortages. Now, researchers have come up with a promising process for protecting seeds from the stress of water shortage during their crucial germination phase, and even providing the plants with extra nutrition at the same time.
Dehydrated plant seeds can lay dormant for long periods–over 1,000 years in some species–before the availability of water can trigger germination. This protects the embryonic plant inside from a variety of environmental stresses until conditions are favorable for growth and survival. However, the mechanism by which the baby plant senses water and reactivates cellular activity has remained a mystery until now.
Biochar, a product made from urban, agriculture and forestry waste has the added benefit of reducing the carbon footprint of modern farming, an international review involving.
Despite being relatively new in China, community-led seedbanks are a valuable resource in conserving agricultural biodiversity. For the first time, researchers have provided a comprehensive summary of the services performed by 27 seedbanks across the country.
