Early Phosphorylation Events of Phototropism Signaling Are Unaffected in d6pk012 Mutants and D6PK Overexpressors.
Immunoblot analyses of phot1, NPH3, PKS4, YFP:D6PK (anti-GFP), and DET3 (loading control) of protein extracts prepared from dark-grown seedlings after 0, 0.5, 5, and 30 min of blue light illumination (1.5 µmol m−2 s−1). Closed arrowheads, top band, phosphorylated form(s); open arrowhead, bottom band.
