Auxin steers root cell expansion via apoplastic pH regulation in Arabidopsis thaliana
Open accessAbstract
Significance: Cellular growth in plants is constrained by cell walls; hence, loosening these structures is required for growth. The long-standing acid growth theory links auxin signaling, apoplastic pH homeostasis, and cellular expansion, providing a conceptual framework for cell expansion in plant shoots. Intriguingly, this model remains heavily debated for roots. Here, we present a fluorescent dye that allows for the correlation of cell size and apoplastic pH at a cellular resolution in Arabidopsis thaliana . This enabled us to elucidate a complex involvement of auxin in root apoplastic pH homeostasis, which is important for root cell expansion and gravitropic response. These findings shed light on the poorly understood acid growth mechanism in roots.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
