Quorum sensing (QS) is a system of cell-to-cell communication by means of intercellular signaling molecules to coordinate a set of targeted gene expression or repression in many Gram-negative bacteria; it plays important roles for bacteria in adaptation to adverse environmental conditions. In this study, we first demonstrated that Microcystis aeruginosa(More)
Integrated photonics provides a miniaturized and potentially implantable platform to manipulate and enhance the interactions between light and biological molecules or tissues in in-vitro and in-vivo settings, and is thus being increasingly adopted in a wide cross-section of biomedical applications ranging from disease diagnosis to optogenetic(More)
Cyanobacteria are the dominant bloom-forming species in Lake Taihu. Understanding the competition among algae is important to control strategies for bloom formation and outbreaks in freshwater ecosystems. In this study, we demonstrate that the cyanobacterium Microcystis aeruginosa PCC7820 and the green alga Quadrigula chodatii FACHB-1080 exhibit a strong(More)
Hirudin variant III (HV3) is potentially useful in the prevention and treatment of cataracts. To prepare sufficient amounts of rHV3 for further preclinical studies, we developed an effective process for robust preparative-scale extracellular production of rHV3 in Escherichia coli. In a 7-l bioreactor, under the optimal fed-batch fermentation conditions,(More)
Omnivores always show flexible foraging habits and actively shift their diets responding to the varying local conditions as well as different ontogenetic trajectories. Littoral fish commonly exhibiting omnivorous diets across pelagic and benthic food webs has the potential effect on trophic dynamics and food web stability. Here, we studied dietary strategy(More)
SRAP molecular marker was used to detect the genetic diversity of 24 mulberry genotypes in the lower regions of the Yellow River in order to analyze the genetic relationships and pedigrees in the genus Morus L. Out of 88 PCR fragments scored, 69 (78.41 %) were polymorphic, with an average of 6.9 polymorphic bands and 8.0 bands per SRAP primer combination. A(More)
Ten universal primer pairs of the plant chloroplast genome were used to amplify the chloroplast DNA (cpDNA) non-coding regions in eight mulberry (Morus spp.) genotypes, including M. mongolica, M. bombycis, M. alba, M. atropurpurea and M. multicaulis. Subsequently, the polymerase chain reaction (PCR) products were digested by seven restriction enzymes and(More)
Thirteen sequence-related amplified polymorphism (SRAP) primers combined with polymerase chain reaction (PCR) were used to evaluate the genetic relationships among 24 genotypes of the genus Malus Mill. including Sect. Malus, Baccatus, Sorbomalus and Chloromeles. Out of 115 surveyed fragments, 107 (93.04%) were polymorphic. Coefficients of genetic similarity(More)
