Mating type‐plus (mt + ; 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 − ; NIES‐229) cells. Light and the presence of mt + 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.
