Abstract

A simple method was devised to measure growth and phototropism in isolated sporangiophores fromPhycomyces blakesleeanus. With this method, the effects of a number of substances that affect different metabolic reactions were tested. A large number of compounds inhibited or stimulated sporangiophore growth, but did not affect the phototropic response. Only colchicine, thiabendazole, and specially trifluoperazine affected both sporangiophore growth and phototropism. These results suggest that microtubules and calmodulin are involved in the response of the fungus to light.
