Green Leaf Volatiles: A Natural Ally in Plant Stress Resistance

Chinese Academy of Sciences — Wed, 23 Oct 2024 09:55:59 EST

Scientists have identified a natural compound, (Z)-3-hexenyl butyrate (HB), that can induce stomatal closure in plants, a defense mechanism to conserve water and protect against pathogens. This discovery could lead to more sustainable agricultural practices by enhancing crop resilience to environmental stresses without the need for synthetic pesticides.

New Parasite Discovered Amid Decline of California's Unique Channel Island Fox

Florida Atlantic University — Wed, 23 Oct 2024 08:30:27 EST

In the 1990s, the San Miguel Island fox nearly went extinct, with numbers dropping to just 15. A recovery program increased their population by 2010, but from 2014 to 2018, it fell to 30% of its peak due to a new acanthocephalan parasite, exacerbated by a prolonged drought. A collaborative research effort employed morphological and molecular methods, alongside necropsy records, to identify the parasite and assess its health impacts on the foxes.

Not Running Dry: UNLV Project Tackles Water Scarcity in Rural Communities

University of Nevada, Las Vegas (UNLV) — Thu, 17 Oct 2024 18:45:16 EST

A UNLV research team is developing sustainable water management solutions for rural arid areas in the U.S. and China, focusing on wastewater reuse through solar-powered treatment processes. The project aims to provide low-cost technologies for non-potable -- and possibly potable -- reuse in rural communities in both countries, addressing water scarcity and quality issues.

Declines in Plant Resilience Threaten Carbon Storage in the Arctic

New Research Reveals How El NinO Caused the Greatest Ever Mass Extinction

University of Bristol — Thu, 12 Sep 2024 14:00:00 EST

Mega ocean warming El Nino events were key in driving the largest extinction of life on planet Earth some 252 million years ago, according to new research.

Revitalizing pak choi: unveiling the genetic mechanisms behind drought tolerance

Chinese Academy of Sciences — Wed, 11 Sep 2024 22:05:46 EST

Scientists have discovered a genetic mechanism in pak choi that boosts drought tolerance by regulating ascorbic acid levels. By silencing the BcSRC2 gene, researchers found that the plant's ascorbic acid content decreased, reducing its drought resistance. Conversely, overexpressing BcSRC2 raised ascorbic acid levels, enhancing the plant's tolerance. This finding could guide future breeding strategies to help crops cope with water scarcity.

Study suggests US droughts, rainy extremes becoming more severe

Ohio State University — Fri, 06 Sep 2024 09:05:56 EST

Severe drought in the American Southwest and Mexico and more severe wet years in the Northeast are the modern norm in North America, according to new research - and the analysis suggests these seasonal patterns will be more extreme in the future.
