Abstract
Mating type-plus (mt(+); NIES-228) cells of Closterium ehrenbergii und ergo a division to form gamete-shaped cells. This cell division is ind uced by a substance-produced by mating type-minus (mt(-); NIES-229) ce lls. Light and the presence of mt(+) cells enhanced production of the substance. The active substance is heat labile and has an apparent mol ecular mass of 20 kDa. From these results, we conclude that the substa nce is a novel, proteinaceous sexual pheromone involved in reproductio n of Closterium ehrenbergii.
