Abstract: | Phytochrome is consistently observed in pellets centrifuged from homogenates of etiolated, 5-day-old oat seedlings. The majority of pigment associated with the pellet cannot be removed by buffer washes, nor can appreciable quantities of additional phytochrome be adsorbed onto the sedimented material. Over 70% of phytochrome in the pellet is released by 1% Triton X-100. |
