Thông tin tài liệu:
Selenium is a trace element found in freshwater and the marine environ-ment. We show that it plays a major role in spicule formation in the demo-sponge Suberites domuncula. If added to primmorphs, an in vitro spongecell culture system, it stimulates the formation of siliceous spicules. Usingdifferential display of transcripts, we demonstrate that, after a 72-h expo-sure of primmorphs to selenium, two genes are up-regulated; one codes forselenoprotein M and the other for a novel spicule-associated protein....
