WebA common feature of phytochrome in almost all plants examined is its rapid degradation upon photoconversion of the red light (R)-absorbing form (Pr) to the far-red light (FR)-absorbing form (Pfr) (Pratt 1979; Jabben and Holmes 1984). In etiolated Cucurbita pepo seedlings for example, this transformation increases the degradation rate of the ...

Webphytochrome chromoproteins exist in two isomeric forms, inactive Pr and active Pfr, that absorb in the red (R) (peak 660 nm) and far-red (FR) light (peak 730 nm), respectively. R light drives photoconversion from Pr to Pfr, while FR light reverses this process.
