Abstract

Plants depend on the surrounding light environment to direct their growth. Blue light (300-500 nm) in particular acts to promote a wide variety of photomorphogenic responses including seedling establishment, phototropism and circadian clock regulation. Several different classes of flavin-based photoreceptors have been identified that mediate the effects of blue light in the dicotyledonous genetic model Arabidopsis thaliana. These include the cryptochromes, the phototropins and members of the Zeitlupe family. In this review, we discuss recent advances, which contribute to our understanding of how these photosensory systems are activated by blue light and how they initiate signaling to regulate diverse aspects of plant development.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • LOV1 and LOV2 are structurally similar but not functionally identical; LOV1 regulates the light response of LOV2, which mainly controls phosphorylation of the kinase domain.

    “Although LOV1 and LOV2 are structurally similar, they are not functionally identical. LOV1 regulates the light response of LOV2, which mainly controls phosphorylation of the kinase domain (Christie et al., 2015; Okajima, 2016).”

    From The action of enhancing weak light capture via phototropic growth and chloroplast movement in plants (2022) · cites this paper as Christie et al., 2015

    In “Phototropin structure and light sensing” (page not provided), the paper describes LOV1 and LOV2 as structurally related light-sensing domains with distinct roles. It says LOV1 is *proposed* to modulate LOV2 photoreactivity, while LOV2 regulates light-dependent autophosphorylation. The claim overstates the certainty of LOV1’s regulatory role, which the paper says remains unclear. (LLM, conf=0.85)

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.
