Protein hunger-driven nitrogen flow from phospholipids to amino acids inDrosophila

Protein is unique among macronutrients due to its nitrogen content and that its building blocks, essential amino acids, cannot be synthesized by animals. Additionally, animals lack specialized amino acid storage sites, necessitating a continuous dietary intake. In the face of insufficient dietary protein, how do animals manage nitrogen limitation? Using Drosophila, we reveal a previously…

Delaying cherry blossom to reduce frost damage

Climate change is causing many fruit trees to flower earlier, increasing their exposure to damaging late spring frosts. A study led by the University of Göttingen shows that the plant growth regulator ethephon can delay flowering in Kordia, a sweet cherry variety, potentially protecting blossoms and developing fruitlets from frost.
