Natural wetlands, occupying 3.8% of China's land and providing 54.9% of ecosystem services, are unevenly distributed among eight wetland regions. Natural wetlands in China suffered great loss and degradation (e.g., 23.0% freshwater swamps, 51.2% costal wetlands) because of the wetland reclamation during China's long history of civilization, and the(More)
Isopentenyl diphosphate (IDP) and its isomer dimethylallyl diphosphate (DMADP) are building units for all isoprenoids; thus, intracellular pool sizes of IDP and DMADP play important roles in living organisms. Several methods have been used to quantify the amount of DMADP or the combined amount of IDP plus DMADP, but measuring the DMADP/IDP ratio has been(More)
Aquatic plants develop strong fragment propagation and colonization ability to endure the natural disturbances. However, detailed research of ability to endure the natural disturbances has been lacking to date. Therefore, reproduction (shoot) and colonization (root) of shoot fragments of Potamogeton crispus L. with or without apices were investigated for(More)
Spartina alterniflora Loisel., a highly invasive species on the Chinese coast, is a focus of increasing management concerns due to its high expansion rate in tideland and the significant damages on native ecosystems, since its introduction into China in 1979. There are both tall and dwarf forms of the species in China. The tall form with strongly invasive(More)
The purpose of this article was to study the trade-offs among vegetative growth, clonal, and sexual reproduction in an aquatic invasive weed Spartina alterniflora that experienced different inundation depths and clonal integration. Here, the rhizome connections between mother and daughter ramets were either severed or left intact. Subsequently, these clones(More)
Many traditional Chinese medicines have been used as immunomodulators that act as either immunosuppressants or immunostimulators. Recently, our lab successfully isolated a monomer telocinobufagin (TCB) from the chloroform extract of Chan Su (Venenum Bufonis). In the present paper, we evaluated the immunomodulatory effects of this compound in vitro. We found(More)
To elucidate the seed–seedling conflict and the process of habitat choices during the expansion of S. alterniflora, densities of seeds and seedlings in three different habitats, foreland, Spartina meadow, and canopy gap patch, were measured. Statistical analyses of these measurements were performed to investigate the interaction between seeds or seedlings(More)
Asparagine (N)-linked glycosylation is one of the most crucial post-translational modifications, which is catalyzed in the lumen of the endoplasmic reticulum (ER) by the oligosaccharyltransferase (OST) in eukaryotic cells. Biochemical and genetic assay leads to the identification of the nine subunits (Ost 1–6, Stt3, Swp1 and Wbp1) of the yeast OST and in(More)
