Nitro‐fatty acids‐mediated nitroalkylation modulates fine‐tuning catalase antioxidant function during salinity stress in plants

Protein Science, Volume 34, Issue 3, March 2025.
Abstract Nitro‐fatty acids (NO2‐FAs) are novel molecules resulting from the interaction of unsaturated fatty acids and nitric oxide (NO) or NO‐related molecules. In plants, it has recently been described that NO2‐FAs trigger a powerful antioxidant and defense response against stressful situations, the induction of the heat‐shock response (HSR), and ...

Meta‐analysis contrasting freshwater biodiversity in forests and oil palm plantations with and without riparian buffers

Conservation Biology, Volume 38, Issue 1, February 2024.
Abstract The expansion of oil palm plantations has led to land‐use change and deforestation in the tropics, which has affected biodiversity. Although the impacts of the crop on terrestrial biodiversity have been extensively reviewed, its effects on freshwater biodiversity remain relatively unexplored.
