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.
