Ultrasound‐Triggered Nanocomposite “Lever” Hydrogels with a Full Repair System Accelerates Diabetic Foot Ulcer Repair

open access: yesAdvanced Science, Volume 12, Issue 23, June 20, 2025.
Ultrasound (US)‐treated nanocomposite ‘lever’ hydrogels reprogrammed wound reactive oxygen species (ROS) levels and promoted wound healing in infected diabetic foot ulcers. Abstract Diabetic foot ulcers (DFUs) are a complex mixture of neuropathy, peripheral arterial disease, and infection, where excessive reactive oxygen species (ROS) exacerbates ...

Mycorrhizal fungi compromise production of endophytic alkaloids, increasing plant susceptibility to an aphid herbivore

open access: yesJournal of Ecology, Volume 113, Issue 6, Page 1368-1381, June 2025.
These findings indicate that symbiotic fungal partnerships and silicon provision may benefit plants but could weaken anti‐herbivore defences when combined. Revealing the complex interactions among diverse fungal symbionts and showcasing their effects on different anti‐herbivore defences (chemical and physical) and herbivore performance for the first ...

Reverse prenylation in plants by non‐canonical aromatic prenyltransferases

open access: yesThe Plant Journal, Volume 122, Issue 6, June 2025.
Significance Statement Aromatic prenyltransferases (aPTs) are key catalysts in plant specialized metabolism, enhancing bioactivity by attaching hydrophobic prenyl groups to aromatic compounds. While no plant aPT catalyzing reverse prenylation of aromatic carbons has been identified so far, this study reports plant UbiA‐type aPTs from Hypericum species,
