Green Leaf Volatiles: A Natural Ally in Plant Stress Resistance
Chinese Academy of Sciences

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

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.

Revitalizing pak choi: unveiling the genetic mechanisms behind drought tolerance
Chinese Academy of Sciences

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.
