| 1 | Molecular identification and biochemical characteristics of a delta class glutathione S-transferase gene(FcδGST)from Chinese shrimp Fenneropenaeus chinensis显示文摘Glutathione S-transferases(GSTs)are a superfamily of multifunction enzymes involved in the regulation of redox homeostasis and innate immune responses against various pathogenic infections in marine invertebrates.In the present study,a delta class GST gene(designated as FcδGST)was cloned from Fenneropenaeus chinensis using rapid amplification of c DNA ends(RACE)technology.The complete cDNA sequence of FcδGST was 780 bp in length,which includes a 27-bp 5′non-coding region(UTR),a 117-bp 3′UTR,a 636-bp open reading frame(ORF),and a polyadenylate signal site(AATAAA)presented at the upstream of poly A tail.The FcδGST gene encoded 211 amino acids peptide,including a GST_N domain and a GST_C domain,and exhibited high similarity with previously reported delta GSTs.The predicted molecular mass of FcδGST protein was 23.39 kDa,and its theoretical isoelectric point(pI)was 5.34.The FcδGST mRNA transcripts were ubiquitously expressed in all the tested tissues,with the highest expression level in hemocytes and hepatopancreas.During the stimulation of Vibrio anguillarum or white spot syndrome virus(WSSV),the m RNA expression of FcδGST in hemocytes and hepatopancreas revealed significant up-regulation.The purified recombinant FcδGST protein(designated as rFcδGST)exhibited specific catalytic activity against 1-chloro-2,4-dinitrobenzene(CDNB)substrate with relatively low stable enzymatic activities.These results indicated that FcδGST was a fragile but typical novel delta class GST member and potentially involved in the innate immune responses of F.chinensis. | Jiaobing LI Yan WANG Jingjie HU Yajin XU Qingqian ZHOU Lu ZHANG Mengqiang WANG | 2023 | Journal of Oceanology and Limnology2023，41，5： | 0 |
| 2 | Effect of fence opening configurations on dune development显示文摘Fences have been widely used in coastal protection engineering for their low cost,simple deployment,and easy integration with ecosystems.The effects of fence porosity and height on dune development have been investigated while not much attention has been paid to the effects of fence opening configurations,such as opening size and geometry,and porosity distributions.In this study,we deployed eight fences with same height and similar porosity,but different opening configurations on a sandy beach in Pingtan,Fujian Province.Results indicate that there is a similar two-dune-one-trough pattern for all fences at the beginning of dune development,and opening size,orientation,and geometry,and porosity distribution control the leeward dune peak locations.Fences with small openings and non-uniform porosity have high trapping efficiency,and upper denser porosity may be the optimal design as these fences have the highest trapping efficiency and capacity.The conclusions from this study can provide guidance on practical fence design. | Qingqian Ning Bailiang Li Changmao Zhou Yanyu He Jianhui Liu | 2023 | Acta Oceanologica Sinica2023，42，7： | 0 |
