Functional Characterization of Phytochrome Interacting Factor 3 in Phytochrome-Mediated Light Signal Transduction

Open access
Kim, J.·2003·THE PLANT CELL ONLINE

Abstract

Phytochromes regulate various light responses through their interactions with different signaling proteins, such as phytochrome interacting factor 3 (PIF3). However, the physiological functions of PIF3 in light signaling are not yet fully understood. To increase our understanding of these roles, we characterized a T-DNA insertional pif3 mutant and transgenic plants overexpressing the full-length PIF3. Transgenic overexpressing lines displayed longer hypocotyls and smaller cotyledons under red light and reduced cotyledon opening under both red and far-red light, whereas the pif3 mutant showed the opposite phenotypes. The accumulation of anthocyanin and chlorophyll further indicated complicated features of PIF3 function. The accumulation of anthocyanin was increased and the content of chlorophyll was decreased in the overexpression lines. Our data indicate that PIF3 plays complex roles depending on the type of light response and the light conditions.

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.
