Abstract
PHYTOCHROME, the red, far-red photo-reversible chromo-protein that controls much of higher plant growth and development, undergoes two changes in the dark following an initial red light exposure. One change, reversion, is the transformation of the far-red absorbing form, PFR, into the red absorbing form PR. A second change, which we will call decay, is the loss of total photo-reversible phytochrome as a result of the apparent destruction of PFR (ref. 1). Since there is considerable indirect evidence that PFR is the active form of phytochrome, the interactions between PFR decay and metabolism may be of significance in elucidating the mechanism of phytochrome action.
