First steps in the phytochrome phototransformation: a comparative femtosecond study on the forward (Pr --> Pfr) and back reaction (Pfr --> Pr).

Abstract

The primary light-induced events in the reversible Pr right harpoon over left harpoon Pfr phototransformation are investigated by femtosecond absorption spectroscopy using a pump-probe technique. After the selective electronic excitation of Pr and Pfr with pulses at 610 and 730 nm, respectively, the transient absorption spectra were measured as a function… (More)
