(22S,23S)-Homobrassinolide was tested for its effect on the electric cell potential, proton extrusion, ferricyanide reduction, and amino acid and sucrose uptake of leaves of Egeria densa Planchon. In the light, (22S,23S)-homobrassinolide and its derivative, 2alpha-3alpha-dihydroxy-5alpha-stigmast-22-en-6-one, were similar to each other and similar to fusicoccin in causing hyperpolarization and ...
