A new study found that inhaling linalool, a key ingredient in aromatherapy, can alter gene activity and blood chemistry to reduce stress levels. The study also showed that linalool returned stress-elevated levels of immune cells to near-normal levels.
A recent study by the American Society for Horticultural Science found that stressors during tree handling and transport, such as root severance, water stress, and mechanical damage, can significantly impact tree health and establishment. Researchers identified key stages in the transplanting process that contribute to reduced growth a...
Researchers at the National Center for Atmospheric Research discovered that plants in a forest produce significant amounts of methyl salicylate, a chemical form of aspirin, in response to stress. This finding has the potential to give farmers an early warning signal about crops that are failing.
Researchers at the University of the Basque Country study plants' defence mechanisms to predict photo-oxidative stress. They discover antioxidants like vitamin E and carotenoids, which help protect plants from excessive light, and identify new cycles like the lutein epoxide cycle.
Research by Dr. Terri W. Starman identified the strongest survivors of postharvest experiences among popular garden plants marketed to consumers. High-quality plants may look healthy but decline in quality within a week, with most becoming unmarketable after three weeks.
Researchers have compiled the world's first detailed gene expression library for Symbiodinium, a microscopic algae that feeds corals and drives the reef's fate. Understanding its biochemical relationship with corals is crucial for addressing coral bleaching and climate change.
Scientists at VIB have discovered a new control system that helps plants cope with stress by containing energy consumption and mobilizing reserves. This finding may be valuable beyond plants, as the proteins involved are also found in mammals and could play a role in understanding disorders such as diabetes and cancer.
Researchers at the Hebrew University of Jerusalem developed a method to increase plant tolerance to salt stress, preventing stunted growth and plant death. The technique uses genetic manipulation to reduce self-induced membrane damage and has significant consequences for dealing with soil salinization.
Researchers found a single pathway that channels distress signals from chloroplasts to the nucleus in plants, enabling the activation or deactivation of certain genes. This 'master switch' could lead to new generations of plants with improved drought and stress tolerance.
Researchers have developed a remote-sensing technology that uses the spectral quality of light reflected from plant leaves to detect gas leaks. This technology can also be used to monitor environmental effects and ensure public acceptability and safety in carbon capture and storage schemes.
Researchers have identified a system in a mutant arabidopsis that signals cells to pause during stressful situations, allowing plants to regulate themselves and adjust before growth resumes. This discovery may lead to breeding plants with improved stress handling techniques and enhanced drought tolerance.
Researchers have identified HsfA1 as a master regulator of the tomato heat stress response, playing a crucial role in protecting plants from high temperatures. Transgenic tomatoes with over-expressed HsfA1 showed increased resistance to heat stress, while those deficient in HsfA1 were more susceptible.
Researchers at Cornell University have discovered that stress can increase the amount of hypericin in St. John's Wort, a popular herbal remedy for depression. The study found that plants under attack from insects produce more hypericin, which may contribute to its effectiveness.
A recent study by Ohio State University suggests that stress levels can motivate smokers to think about quitting. Contrary to popular belief, high stress does not discourage smokers but rather heightens their awareness of the health risks associated with smoking.
