The notations Pr and Pfr were recently changed to Pr and Pfr. Is that standard? In published papers, I keep seeing the non-subscripted version: [1], [2]. Cheers, AxelBoldt 15:07, 8 May 2006 (UTC)

You're right. The non-supscripted versions are standard. Also, the P in Pr / Pfr stands for "pigment" not "phytochrome" - I changed that (but left subscripts for now).

Indeed, subscripting is not mandatory. I removed the archaeic structure illustration of phytochromobilin and the poor diagram showing the UV-Vis absorbance spectra of Pr and "Pfr" (which was the spectrum of a Pr / Pfr mixture). Also I have changed "form" and "isoform" to "state" (thus "ground state", "signalling state") which is more in line with current useage in photobiology and photochemistry.
