Mutated genes

Locus name Alias Hormone Mutated site Paper description
AT2G02950 PKS1 auxin 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.
AT1G14280 PKS2 auxin Encodes phytochrome kinase substrate 2. PKS proteins are critical for hypocotyl phototropism. Forms a complex with Phot1, Phot2 and NPH3.
AT5G04190 PKS4 auxin Encodes phytochrome kinase substrate 4, a phytochrome signaling component involved in phototropism.
