- Abstract
Mating type-plus (mt[SUP-]; NIES-228) cells of Closterium ehrenbergii undergo a division to form gamete-shaped cells. This cell division is induced by a substance produced by mating type-minus (mt[SUP-]; NHES-229) cells. Light and the presence of mt[SUP-] Cells enhanced production of the substance. The active substance is heat labile and has an apparent molecular mass of 20 kDa. From these results, we conclude that the substance is a novel, proteinaceous sexual pheromone involved in reproduction of Closterium ehrenbergii.
