Streptomyces spp. are well-known producers of secondary metabolites with diverse biological activities. We screened the substances that regulate polyp-to-jellyfish transition, called strobilation, of the moon jellyfish (Aurelia coerulea) from the Str

In our previous publication, we identified novel gene candidates involved in shell formation by EST analyses of the nacreous and prismatic layer-forming tissues in the pearl oyster Pinctada fucata. In the present study, 14 of those genes, including t

Invertebrates change the metabolite concentrations in their bodies to adapt to environmental salinity. The kuruma shrimp Marsupenaeus japonicus is one such invertebrate. It lives in coastal areas and is also known to change free amino acid concentrat

Cyclic guanidines are found in many biologically active compounds and natural products. Further, the for-mation of the atypical 7-membered ring of cyclic guanidine remains challenging due to a lack of efficient preparation strategies and low yield. H
