Abstract
Scopelophila cataractae (Mitt.) Broth. is one of the interesting moss that often grows under copper rich environments, such as under copper roofs of temple, and this moss accumulates copper in the body. However, physiological knowledge about a mechanism of copper tolerance and style that expands distribution of this moss is still almost unknown. Thus, we are analyzing the response to the copper of S.cataractae. First of all, to elucidate the response to the copper, we examined the effect of the copper treatment on the protonema growth. As a result, compared with control, the diameter of the 14 day cultured protonemal colony has increased by the copper treatment (up to 800μM). In contrast, number of protonamal gemma formations has increased in the control. These result suggest that S.cataractae has the ability to change the morphogenesis according to the environmental copper concentration.
