Transposase-Derived Transcription Factors Regulate Light Signaling in Arabidopsis
Open accessAbstract
Plants use light to optimize growth and development. The photoreceptor phytochrome A (phyA) mediates various far-red light–induced responses. We show that Arabidopsis FHY3 and FAR1 , which encode two proteins related to Mutator -like transposases, act together to modulate phyA signaling by directly activating the transcription of FHY1 and FHL , whose products are essential for light-induced phyA nuclear accumulation and subsequent light responses. FHY3 and FAR1 have separable DNA binding and transcriptional activation domains that are highly conserved in Mutator -like transposases. Further, expression of FHY3 and FAR1 is negatively regulated by phyA signaling. We propose that FHY3 and FAR1 represent transcription factors that have been co-opted from an ancient Mutator -like transposase(s) to modulate phyA-signaling homeostasis in higher plants.

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.
