Research Abstract

Although the blue light (BL)receptor, AUREOCHROME we dis-covered regulates photomorphogenesis in Vaucheria, in brown algae, which are biologically and industrially far more important than others, nothing is known about AUREO-CHROME's function. I chose Halopteris after surveying small brown algal species easily cultivable and having simplest organization. Culturing H. congesta in a long-day condi-tion with monochromatic blue-or red LED lamps, I found that only BL permits the alga's growth but not the red light.
