Calmodulin-like protein from the fern Anemia phyllitidis L. Sw.

Spores and prothallia of the fern Anemia phyllitidis L. Sw. contain a protein which in its physicochemical properties corresponds largely to calmodulin. It shows immunoreactivity with a calmodulin antiserum and activates bovine brain phosphodiesterase. Its content increases during the early processes of light-induced spore germination, indicating that the Ca(2+)-dependence of these processes may be mediated by this protein.
