Effects of water stress on induction and secretion of cellulase and on branching in the water mold Achlya ambisexualis

Abstract

Water stress inhibits the branching response of the water mold Achlya ambisexualis to the sexual hormone antheridiol. The relative sensitivities of the experimental parameters to water stress are as follows: branching > cellulase secretion > cellulase induction. Secretion of cellulase is completely inhibited by a 0.3 M concentration of osmoticum.
