Our new Nat Plants paper introduces WALLΦ, a genetically encoded cell wall pH sensor, and reveals that root developmental zonation is independent of local cell wall pH. Wall pH supports growth at the organ level, but local growth patterns are governed by other mechanisms. doi.org/10.1038/s414...

Congratulations to Monika Kubalová from our lab on her new first-author publication in PNAS. www.pnas.org/doi/10.1073/... The study uncovers how auxin controls gibberellin levels in Arabidopsis roots through gibberellin-deactivating enzymes GA2OX6 and GA2OX8.
Gibberellin-deactivating GA2OX enzymes act as a hub for auxin–gibberellin cross talk in Arabidopsis thaliana root growth regulation | PNAS
Plant bodies are built from immobile cells, making the regulation of cell expansion
essential for growth, development, and adaptation. In roots, ce...
