RESUMO

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 sulfate polyacrylamide gel electrophoresis (Boeshore ML, LH Pratt 1980 Plant Physiol 66: 500-504). The electrophoretic mobility of several different kinds of phytochrome preparations were examined to study how this modification might arise.
