Reversible Root Tip Rotation in Arabidopsis Seedlings Induced by Obstacle-Touching Stimulus
Abstract
In soil, downwardly growing plant roots frequently alter their growth direction to escape obstacles that lie in their paths. This response has been analyzed with a simple system that provides a constant obstacle-touching stimulus to root tips of young seedlings of Arabidopsis thaliana . On the surface of agar plates, which were set at an angle of 45° to the vertical, the roots exhibit a wavy growth pattern that is caused by periodic reversion of rotation of the root tip. A set of mutants with abnormal wavy growth was used to demonstrate that at least six genes are involved in this stimulus-response interaction.

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.
