Dry Days Trigger Leaves to Send a Surprising Growth Signal Telling Roots to Keep Growing

Scientists have discovered a new molecular signalling pathway, triggered when leaves are exposed to low humidity, that ensures plant roots keep growing towards water. A new study has found that when the leaves of a plant are exposed to dry air (low ...

Global Analysis on Pollinators in Cities: Wild Bees and Butterflies Are at Particular Risk

Butterflies are being hit hardest by urban growth. Shrinking habitats and food availability are causing their populations to decline. The same applies to many wild bees that fly early in spring. According to a new study, pollination has not yet been ...

A Roadmap for Gene Regulation in Plants

第一次,科学家开发出了一种genome-scale way to map the regulatory role of transcription factors, proteins that play a key role in gene expression and determining a plant's physiological traits. Their work reveals unprecedented insights into gene regulatory networks and ...

Plants Can Distinguish When Touch Starts and Stops, Study Suggests

Even without nerves, plants can sense when something touches them and when it lets go, a study has found. In a set of experiments, individual plant cells responded to the touch of a very fine glass ...

Light Conveyed by the Signal Transmitting Molecule Sucrose Controls Growth of Plant Roots

Researchers shows how information about the quantity of absorbed light passes from the leaves to the roots. Photosynthetic sucrose not only supplies roots with carbohydrates but also acts as a signal ...

Groundbreaking Images of Root Chemicals Offer New Insights on Plant Growth

Applying imaging technology to plant roots, researchers have developed a new understanding of chemicals that are responsible for plant growth. The chemical 'roadmap' identifies where key ...

Weevils, Long-Nosed Beetles, Are Unsung Heroes of Pollination

Some of nature's most diverse pollinators often go unnoticed, even by scientists: long-snouted beetles called weevils. A new study provides a deep dive into the more than 600 species of weevils, ...

Prescribed Burns Encourage Foul-Smelling Invaders

Though prescribed burns reduce wildfire threats and even improve habitat for some animals, new research shows these fires also spread stinknet, an aptly named weed currently invading superblooms ...

Researchers Find New Mechanism for Sodium Salt Detoxification in Plants

A team of researchers has found a mechanism in thale cress (Arabidopsis thaliana) which enables plants to provide protection against salt stress for their sensitive stem cells in the meristem at the ...

Identifying the Bee's Knees of Bumble Bee Diets

A new study has identified the bee's knees of bumble bee dietary options in Ohio and the Upper Midwest. By viewing almost 23,000 bumble bee-flower interactions over two years, researchers found ...

A Guide Through the Genome

Plants show enormous variety in traits relevant to breeding, such as plant height, yield and resistance to pests. One of the greatest challenges in modern plant research is to identify the ...

How Plants Use Sugar to Produce Roots

Along with sugar reallocation, a basic molecular mechanism within plants controls the formation of new lateral roots. Botanists have demonstrated that it is based on the activity of a certain factor, ...

Rare Tropical Plant Gains Appetite for Meat

Researchers Close to Unleashing Rapeseed's Protein Power for Human Consumption

Half of plant proteins in the EU come from rapeseed plants. Until now, the plant has only been used for oil and animal feed, as it is both bitter and unsafe for human consumption. In a new study, ...

Fossil Find in California Shakes Up the Natural History of Cycad Plants

According to researchers, a new analysis of an 80-million-year-old permineralized pollen cone found in the Campanian Holz Shale formation located in Silverado Canyon, California, offers a more ...

'Zero Plant Extinction' Is Possible, Says Plant Ecologist

Like animals, many plant species are struggling to adapt to a human-dominated planet. However, plants are often overlooked in conservation efforts, even though they are cheaper and easier to protect ...

Researchers Model 'Link' Between Improved Photosynthesis and Increased Yield
