The xiamycins are bioactive indolosesquiterpenoids that have been isolated from actinobacterial strains belonging to the Streptomyces genus. The overexpression of orf2011 , which encodes the LuxR family regulator in a marine Streptomyces strain (HK18) isolated from a hypersaline saltern, significantly increased the production of xiamycin dimers, namely the previously reported dixiamycins A and C ( 3 and 4 ), compared to the wi...

Olive flounder (Paralichthys olivaceus) is a vital aquaculture species in East Asia. However, few studies that estimate the genetic parameters of this species have been conducted. We estimated the genetic parameters of growth traits and designed an optimum breeding programme for this species. Heritability, genetic and phenotypic correlations, and breeding values were estimated for growth traits: body weight (BW), total length...
