Pentatricopeptide repeat proteins in crops: Advances in functional mechanisms and breeding applications

Journal of Integrative Plant Biology, EarlyView.
Pentatricopeptide repeat proteins coordinate nucleus‐organelle communication by modulating RNA metabolism within chloroplasts and mitochondria. This review highlights how they control critical processes like photosynthesis, seed development, fertility restoration, and stress survival in crops, and explores their potential as programmable tools for RNA ...

Aquatic macrophytes as nature‐based solutions: Challenges and opportunities across inland and coastal waters

Limnology and Oceanography Letters, Volume 11, Issue 4, July 2026.
Abstract Macrophytes are foundation species whose use as nature‐based solution (NbS) in aquatic ecosystems can help reduce climate change impacts while mitigating biodiversity loss. The discrepancy in research and application of macrophytes as NbS across inland and marine coastal ecosystems is an opportunity to expand the concept and learn from ...
