Characterization of a molecular modification of phytochrome that is associated with its conversion to the far-red-absorbing form.


Phytochrome that has been photoinduced to pellet by irradiation of intact oat (cv. Garry) shoots and recovered from a pellet obtained by centrifugation of crude extracts exhibits modified behavior when compared to soluble phytochrome isolated from shoots that had never been irradiated. This modified behavior includes retarded mobility during sodium dodecyl… (More)
