Description:
AbstractThe 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.
