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.
PKS2 acts in phot1 and phot2 signaling pathways controlling leaf positioning and leaf flattening but not chloroplast movements and stomatal opening.
Title: The Arabidopsis PHYTOCHROME KINASE SUBSTRATE2 protein is a phototropin signaling element that regulates leaf flattening and leaf positioning.
changes in PKS1 or PKS2 content may affect the total phytochrome A concentration [PKS2]
Title: PKS1 and PKS2 affect the phyA state in etiolated Arabidopsis seedlings.
