How do rootstocks mediate scion salinity tolerance under salt stress?
Grafting in tomato has been investigated mainly in small-scale experiments, demonstrating morphological, physiological, and metabolic changes in the scion mediated by the rootstock. By grafting a scion onto different rootstocks, scion salt tolerance.....»»
Study reveals how bacterial pathogen adapts to nutritional stress
In order to cause disease, the human pathogen Staphylococcus aureus must adapt to the changing host environment. Many of these adaptations are mediated through two-component signal transduction systems (TCSs) that coordinate gene expression in respon.....»»

Nanograins: Study finds curious properties of tiny crystals hold clues to earthquake formation
In Earth's crust, tectonic blocks slide and grind past each other like enormous ships loosed from anchor. Earthquakes are generated along these fault zones when enough stress builds for a block to stick, then suddenly slip......»»
Independent stress response makes octocorals more robust
Coral reefs are among the most species-rich ecosystems on the planet. Octocorals, which include soft corals, gorgonians, and sea pens, are important members of these marine communities. They could even outcompete reef-building stony corals in the fut.....»»
Rodents could be asymptomatic carriers of SARS-like coronaviruses, study suggests
Some ancestral rodents likely had repeated infections with SARS-like coronaviruses, leading them to acquire tolerance or resistance to the pathogens, according to new research. This raises the possibility that modern rodents may be reservoirs of SARS.....»»
Advanced microscopes help scientists understand how cells break down proteins
Researchers have used advanced electron microscopes to delve deeper into the process of protein degradation. They described the structure of a key enzyme that helps mediate ubiquitination in yeast, part of a cellular process called the N-degron pathw.....»»
Study links stress to Crohn’s disease flare-ups
Researchers using mouse models found that stress hormones suppressed the innate immune system that normally protects the gut from invasive Enterobacteriaceae, a group of bacteria including E. coli which has been linked to Crohn's disease......»»
Chronic stress and depression boost this brain receptor; a new study maps out how to block it
Eliminating GPR158 activity in stressed mice made them resistant to depression and anxiety. A new study in the journal Science reveals the unusual brain receptor's structure, and possible ways a medication might reduce its sway......»»
