Circadian dysfunction causes aberrant hypocotyl elongation patterns in Arabidopsis

Open access

Abstract

Summary: Many endogenous and environmental signals control seedling growth, including several phototransduction pathways. We demonstrate that the circadian clock controls the elongation of the Arabidopsis hypocotyl immediately upon germination. The pattern of hypocotyl elongation in constant light includes a daily growth arrest spanning subjective dawn and an interval of rapid growth at subjective dusk. Maximal hypocotyl growth coincides with the phase during which the cotyledons are raised, in the previously described rhythm of cotyledon movement. The rhythm of hypocotyl elongation was entrained by light–dark cycles applied to the imbibed seed and its period was shortened in the toc1–1 mutant, indicating that it is controlled by a similar circadian system to other rhythmic markers. The daily growth arrest is abolished by the early flowering 3 (elf3) mutation, suggesting that this defect may cause its long‐hypocotyl phenotype. Mutations that affect the circadian system can therefore cause gross morphological phenotypes, not because the wild‐type gene functions pleiotropically in several signalling pathways, but rather because the circadian clock exerts widespread control over plant physiology.

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.
