Abstract
Castasterone was found to be a biosynthetic precursor of brassinolide using Catharanthus roseus crown gall cells. However, castasterone was not converted to brassinolide in tissues of mung bean and rice, indicating that growth-promoting activity of castasterone observed in these tissues was exerted by castasterone itself.
