Microbes Play Role in Corn ‘Hybrid Vigor’

By | News, Plant Health, Plant Science

Researchers have shown that soil microbes – microscopic organisms like viruses, bacteria and fungi found throughout nature – play a role in the phenomenon of heterosis or “hybrid vigor,” the superior performance of crossed plant lines, or hybrids, over inbred plant lines. Hybrids are often used by farmers for agricultural production due their superior crop yields.

DNA duplication linked to the origin and evolution of pine trees and their relatives

By | Forestry, News, Plant Science

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.

How climate change and fires are shaping the forests of the future – Tracking future forest fires with AI

By | Climate change, News, Plant Science

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.

Engineering seeds to resist drought

By | Climate change, News, Plant Science

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.
