Summary: Strigolactone (SL) plays a key role in regulating plant growth, development, and stress response. Exogenous SL can enhance watermelon resistance against herbicides by promoting antioxidant enzyme activity and up-regulating detoxification-related genes, alleviating the damage caused by herbicides to watermelon roots and leaves.

Summary: Sasa borealis, also known as broad-leaf bamboo, is a plant known for its abundance of bioactive natural products and its traditional medicinal uses. This study investigated the antioxidant activity of S. borealis hot water extract and its potential in reducing oxidative stress. The extract showed dose-dependent antioxidant effects and was found to reduce intracellular reactive oxygen species and protect against oxidative stress-induced apoptosis. The extract also induced the production of antioxidant enzymes. These findings suggest that S. borealis extract may be used in the development of nutraceuticals and functional foods to alleviate oxidative stress in kidney injury.

Summary: Drought is a major threat to global agricultural production, affecting over 43% of cropped areas worldwide. The study found that sorghum water extract can effectively enhance drought tolerance in wheat by improving morpho-physiological attributes, increasing antioxidant enzyme activities, reducing oxidative stress, and enhancing chlorophyll contents in the plants. These improvements contribute to mitigating the negative effects of drought on crops.

Summary: This study aims to detect the in situ production of reactive oxygen and nitrogen species (RONS), specifically superoxide anion (O-2(center dot-)), in aqueous buffer solutions exposed to cold atmospheric plasmas (CAPs). The production and accumulation of RONS in the liquids were found to depend on the plasma composition, with N-2-based shieldings providing the highest concentrations of superoxide. The study provides valuable insights into the interactions between CAPs and physiological solutions for biomedical applications.
