A new study provides key insights into how and why tree populations migrate in response to climate change at the continental scale.
We rely on pollinators like honeybees to grow a wide array of the world’s crops. But that same reliance may put plants at risk of disease, according to new research. In the first study to take a broad look at virus hitchhikers on pollen grains, biologists show that a variety of viruses travel on pollen — especially in areas close to agriculture and human development where honeybees dominate.
How does a developing plant shoot know how, where, and when to grow? Dividing cells need to pass messages from one another to coordinate growth. In plants, important messages are packaged into RNA, which are sent from cell to cell. By studying Arabidopsis thaliana, researchers found that RNA messages need a special protein to escort them where they need to go. Without this escort, cells cannot coordinate and the plant fails to develop properly.
Scientists are honing the traits of speed, strength and near invulnerability in sorghum, a very important food crop. Achieving a milestone in their pursuit of the Superman of sorghum plants, scientists identified a single gene that confers broad protection from the fungal diseases anthracnose, rust and target spot.
What determines how a cell’s genome is regulated to ensure proper growth and development? Turns out, the parts of the genome that are turned on or off in each cell-type or tissue play a major role in this process. Now, a research team has shown that the CLASSY gene family regulates which parts of the genome are turned off in a tissue-specific manner. The CLASSYs essentially control where the genome is marked by DNA methylation—the addition of methyl chemical groups to the DNA that act like tags saying, “turn off.” Because DNA methylation exists across diverse organisms, including plants and animals, this research has broad implications for both agriculture and medicine.
The fascinating world of plants will be once more in the spotlight thanks to the EPSO, which invites you to celebrate the sixth Fascination of Plants Day on and around May 18th 2022. For this purpose, scientific institutions together with schools, farmers and companies will offer a variety of plant-based interactive events and activities for all interested people from toddlers to grandparents.
Researchers recently announced that they have discovered the genetic linkages governing the formation of flowers. The revelation solves a long-standing mystery—how are there so many different types of flowers in the world?—and shines a bright light into a dark corner of evolution. The research also demonstrates the power of a technique called “forward genetics” in uncovering the mysteries of nature.
Researchers have unearthed the earliest definitive evidence of broomcorn millet (Panicum miliaceum) in ancient Iraq, challenging our understanding of humanity’s earliest agricultural practices.
Most trees live in symbiosis with fungi. Researchers show just how important this partnership is for tree growth through the first-ever comprehensive data analysis compiled for European forests on a massive scale.
