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.....»»
Researchers uncover biological circuit that offers a new avenue for creating drought-resistant crops
Climate change is already harming agricultural yields and may one day pose a significant threat to the world's food supply. Engineering more resilient crops, including those able to thrive in the face of drought or high soil salinity levels, is an in.....»»
Common food preservative has unexpected effects on the gut microbiome
Food manufacturers often add preservatives to food products to keep them fresh. The purpose of these preservatives is to kill microbes that could break down and otherwise spoil the food. Common additives like sugar, salt, vinegar and alcohol have bee.....»»
Transcription factor"s key role in grafted cucumbers reveals salt tolerance in crops
Soil salinity, impacting about 1 billion square hectometers worldwide, significantly hinders crop growth. Plants counteract this through signaling pathways involving molecules such as H2O2 and ABA. NAC transcription factors, which are unique to plant.....»»
As sea otters recolonize California estuary, they restore its degraded geology
In the several decades since sea otters began to recolonize their former habitat in Elkhorn Slough, a salt marsh-dominated coastal estuary in central California, remarkable changes have occurred in the landscape......»»
Zebrafish usp3 loss found to promote hypoxic tolerance
Oxygen is an essential element for survival. Ocean warming, circadian rhythm, eutrophication, high-density aquaculture, power failures and long-distance live animal transportation can all lead to low oxygen levels in water. This reduction in oxygen c.....»»
"The Real Housewives of Salt Lake City" once again has the internet in an uproar
Monica Garcia, the fan-favorite of 'Real Housewives of Salt Lake City' Season 4, is not coming back for Season 5 — and fans have a lot to say. Plus, more reunion drama sparks internet discourse. A stunningly surreal season of The Real Housewi.....»»
Follow the salt: Connecting salt concentrations and motion in roundworms
Joint research led by Ayaka Matsumoto and Yuichi Iino of the University of Tokyo demonstrates that temporal decrease in salt concentration leads to the activation of the neck motor neuron of roundworms, but only in a specific phase of its activity......»»
Endosomal stress, a newly defined organelle stress, induces inflammation via ubiquitin signaling
The endosome is an essential organelle located at the center of membrane traffic and mainly sorts plasma membrane proteins internalized by endocytosis in cooperation with ubiquitination, especially lysine-63-linked polyubiquitin chains (K63 ubiquitin.....»»
One billion people left dangerously exposed to heat stress by gaps in climate monitoring
2023 was the hottest year on record. Humidity is rising too. Heat and humidity are a dangerous combination, threatening all aspects of our lives and livelihoods......»»
Salt, microbes, acid and heat in food preservation
In an era of grocery stores and home refrigerators, it is easy to lose sight of the fact that, for most of history, people have been bound by the seasonality of food. This reality has long presented humanity with a conundrum: how to keep eating after.....»»
Sustainable practices could save Mexico"s blue agave, tequila and bats
Many associate tequila with lime wedges, salt and parties. But the popular drink also has a negative impact on biodiversity, both on the blue agave from which it is made and, perhaps more unexpectedly, on bats. Both are threatened by one-sided cultiv.....»»
How winter storms stress San Luis Obispo County elephant seals in the midst of birthing season
The late December morning rain left droplets on Christine Heinrichs' glasses as she stood among a throng of tourists and watched dozens of elephant seals tussle and sleep on a beach just south of the Piedras Blancas Light Station......»»
Researchers discover rare phages that attack dormant bacteria
In nature, most bacteria live on the bare minimum. If they experience nutrient deficiency or stress, they shut down their metabolism in a controlled manner and go into a resting state. In this stand-by mode, certain metabolic processes still take pla.....»»
Repeated sexual failures cause social stress in fruit flies
Repeated failures to reproduce make fruit flies stressed and frustrated, which in turn makes them less resilient to other types of stress, Julia Ryvkin at Bar-Ilan University and colleagues report in PLOS Genetics......»»
New study reveals impact of skin microorganisms on earthworm toxicity in polluted environments
In a study published in the journal Eco-Environment & Health, researchers from Zhejiang University revealed the crucial role of epidermal microorganisms in influencing earthworm toxicity under environmental stress, notably in conditions of nano zero-.....»»
Understanding man-made earthquakes: Study highlights role of fault roughness and stress heterogeneity
Man-made earthquakes, or induced seismicity, have become an increasing concern. These events can occur during fluid injection or extraction, such as in oil or gas reservoirs, wastewater disposal, or geothermal reservoirs......»»
Students do better and schools are more stable when teachers get mental health support
When it comes to mental health at school, typically the focus is on helping students, especially as they emerge from the pandemic with heightened levels of anxiety, stress and emotional need. But as school officials seek to put resources toward stude.....»»
Scientists discover southern Africa"s temps will rise past rhinos" tolerance
Southern Africa contains the vast majority of the world's remaining populations of both black and white rhinoceroses (80% and 92%, respectively). The region's climate is changing rapidly as a result global warming. Traditional conservation efforts ai.....»»
Innovations in 2D root phenotyping uncover genetic keys to enhanced agricultural productivity
Root system architecture (RSA) plays a pivotal role in plant yield, shaped by evolution and ecological adaptations for effective nutrient and water uptake and abiotic stress resistance......»»
Concrete made stronger and more durable with resin
Engineering structures made of concrete, steel, or other materials are subject to vibrations and stress. Because of this, small cracks appear, which grow and eventually lead to destruction. This phenomenon is called "fatigue failure.".....»»
