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.
