A Role for LKP2 in the Circadian Clock of Arabidopsis
Open accessAbstract
A third member of the ZTL gene family was identified in the Arabidopsis genome and was named LKP2 (for LOV kelch protein2). A cDNA was isolated corresponding to this gene, and plants overexpressing LKP2 were generated. The overexpression of LKP2 resulted in arrhythmic phenotypes for a number of circadian clock outputs in both constant light and constant darkness, long hypocotyls under multiple fluences of both red and blue light, and a loss of photoperiodic control of flowering time. The LKP2 mRNA is not regulated by the circadian clock and was detected in all tissues examined. These results suggest that LKP2 functions either within or very close to the circadian oscillator in Arabidopsis. A model is presented for its mode of action.

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.
