| Absorption Spectra of Phytochrome Intermediates  | | | | Abstract
| Native phytochrome (124kdalton) was isolated from etiolated seedlings o f Avena sativa L. cv. Pirol (Baywa, Munich). From low temperature spectra (0 ° C to — 1 6 5 °C) o f phytochrom e samples irradiated either with red or far-red light, spectra o f interm ediates were calculated. Both absorption bands o f the phytochrome chromophore were reported. On the pathway P r -i V r , native phytochrome does not form a bleached interm ediate (m eta-R b) in contrast to degraded phytochrome. An additional intermediate, meta-Rc (/ max = 725 nm), is form ed instead. On the reverse path way only two intermediates were found, lum i-F and m eta-F. O scillator strengths' values were calculated and interpreted in terms o f chromophore conform ation. A schem e o f interm ediates for native phytochrome is presented. | | | |
