 Title    Action of Brassinosteroids on the Epithelial Cell Line from Chironomus tentans  
 Abstract    The two brassinosteroids, 22S',23S'-homobrassinolide and 22S',23S'-homocastasterone are weak com petitors o f the binding o f [3H]ponasterone A to the intracellular ecdysteroid receptor from the epithelial cell line from Chironom us tentans. The relative affinities to the ecdysteroid receptor are 0.001 for both brassinosteroids as compared to 20-OH-ecdysone and 0.1 in com ­ parison to ecdysone. Both substances exert m orphological effects similar to those observed with 20-OH-ecdysone. Like m oulting horm ones both brassinosteroids inhibit chitin synthesis. However, these effects were observed only at rather high concentrations (10-5 to 10"4 m) which were cytotoxic for 22 5,23 S'-homobrassinolide.
