Project description:Sea cucumber, Apostichopus japonicus is a very important species for aquaculture, and its behavior and physiology can respond to the initial change in salinity. It is important to understand the molecular responses of A. japonicus when exposed to ambient changes in salinity In this study, RNA-seq provided a general overview of the gene expression profiles of the intestine of A. japonicus exposed to high salinity (SD40), normal salinity (SD30) and low salinity (SD20) environment.
Project description:The sea cucumber Apostichopus japonicus is a deposit-feeder and vital for marine benthic ecosystems. Hypoxia lasting for several days can lead to massive mortality in A. japonicus. It is important to understand the molecular responses of A. japonicus when exposed to acute changes in DO concentration. In the present study, RNA-seq provided a general overview of the gene expression profiles of the respiratory tree of A. japonicus exposed to dissolved oxygen (DO) of 8 mg/L (DO8), 4 mg/L (DO4) and 2 mg/L (DO2) conditions.
Project description:RNA-seq provided a general overview of the gene expression profiles of the body walls of A. japonicus exposed to strong light (“light”), normal light (“control”) and fully dark (“dark”) environment.
Project description:Leojaponin (2), a labdane diterpene, was isolated from the EtOH extract of the herb of Leonurus japonicus together with a new halimane diterpene named isoleojaponin (1). Isoleojaponin has a new diterpene skeleton with a unique cross-conjugated ?,?-unsaturated ketone system, Their structures were elucidated by physical and spectroscopic analysis, and the relative configuration of the chiral C-9 carbon was determined by a computational method, and analysis of its possible biogenesis pathways.
