Immunohistochemical Detection of Blue Light-Induced Phosphorylation of the Plasma Membrane H+-ATPase in Stomatal Guard Cells

Blue light (BL) receptor phototropins activate the plasma membrane H+-ATPase in guard cells through phosphorylation of a penultimate threonine and subsequent binding of the 14-3-3 protein to the phosphorylated C-terminus of H+-ATPase, mediating stomatal opening. To date, detection of the phosphoryla...
