Tetrapyrroles 25-37 serine/threonine-protein kinase AFC1 Arabidopsis thaliana 72-77 17416636-11 2007 These results suggest the existence of the tetrapyrrole biosynthetic pathway controlled by AtHEMA2 and AtFC1, which normally functions for heme biosynthesis in nonphotosynthetic tissues, but is induced in photosynthetic tissues under oxidative conditions to supply heme for defensive hemoproteins outside plastids. Tetrapyrroles 43-55 serine/threonine-protein kinase AFC1 Arabidopsis thaliana 103-108
