Also known as
phytochrome kinase substrate 1; PHYTOCHROME KINASE SUBSTRATE 1; T17M13.12; T17M13_12
Summary
Encodes a basic soluble protein which can independently bind to either PHYA or PHYB, regardless of whether the phytochromes are in the Pr or Pfr state. PKS1 can be phosphorylated by oat phyA in vitro in a light regulated manner. It is postulated to be a negative regulator of phyB signalling.

What's a GeneRIF?
  1. PKS proteins are involved in auxin signaling and/or lateral auxin redistribution.
    Title: Reduced phototropism in pks mutants may be due to altered auxin-regulated gene expression or reduced lateral auxin transport.
  2. The role of PKS1, along with phyA and phyB, in the positive phototropic responses to red light in Arabidopsis roots is reported.
    Title: PKS1 plays a role in red-light-based positive phototropism in roots.
  3. PKS1 positively affects root phototropism and both effects contribute to negative curvature in response to unilateral blue light.

  4. changes in PKS1 or PKS2 content may affect the total phytochrome A concentration
    Title: PKS1 and PKS2 affect the phyA state in etiolated Arabidopsis seedlings.
  5. PKS1 induction by a pulse of blue light is phytochrome A-dependent, suggesting that the PKS proteins may provide a molecular link between these two photoreceptor families.
    Title: PHYTOCHROME KINASE SUBSTRATE 1 is a phototropin 1 binding protein required for phototropism.
