| Abstract: | The effect of in vitro irradiations on ihe pelletability of peroxitlase activity was tested in extracts prepared from leaves of light-grown spinach (Spinacia oleracea). It appeared that far red light increased the pelletable activity and that red light reversed this effect. This phytochrome-mediated effect occurred in a particulate fraction which banded at 39% (w/w) sucrose on an isopycnic density gradient. |
