| 2 | Distribution characteristics of seamount cobalt-rich ferromanganese crusts and the determination of the size of areas for exploration and exploitation显示文摘In 2001,the International Seabed Authority (ISBA) initiated the consideration relating to the Regulations for Prospecting and Exploration for Hydrothermal Polymetallic Sulphides and Cobalt-rich Ferromanganese Crusts in the Area at its 7th session.Since then,the consideration of the Regulations has been mainly focused on the size of areas to be allocated for exploration and exploitation of the crusts.This paper,based on the investigation data and the analysis of the distribution characteristics of the crusts,suggests a model for determining the size of areas for exploration and exploitation of the crusts,taking into account various factors such as production scale,crust thickness and grade,mineable area proportion,recovery efficiency,exploration venture,and so on.Through the modeling, the paper suggests that the exploration area (the area covered by each application for approval of a plan of work for exploration of cobalt-rich crusts) shall be 4 856 km 2 and the exploitation area (the mine site area) shall be 1 214 km 2,for 20 years of 1 million wet tonnes annual production. | HE Gaowen MA Weilin SONG Chengbing YANG Shengxiong ZHU Benduo YAO Huiqiang JIANG Xunxiong CHENG Yongshou | 2011 | Acta Oceanologica Sinica2011,30,3: | 9 |
| 3 | Biomineralization of phototrophic microbes in silica-enriched hot springs in South China显示文摘Microbial mats in two hot springs in South China were sampled for the research of mineralization of microbes and its mechanism by the methods of geology and modern biology. The results show that hot spring microbes have the key capability for enrichment of Si, Al, Fe, Ca and other elements, and the microbes are also crucial for the formation of SiO2, CaCO3, clay and so on. The extracellular polymeric substances (EPS) play important roles in the process of mineralization of hot spring microbes, which mainly takes place in the layer of EPS outside cell wall or sheath of cyanobacteria. The sheath outside cell wall, which keeps the normal metabolism of cyanobacteria during the process of mineralization on its surface, is also considerable for the biomineralization of cyanobacteria. According to structure and mineralization characteristics of two microbial mats, the process of mineralization can be divided into three stages, namely, early surface mineralization, middle degradation mineralization, and late des- quamation of mineral. The above conclusions are significant for comprehension of the process of mineralization, the process of deposition and the preservation of microfossil in modern and ancient extreme environments. | PENG XiaoTong ZHOU HuaiYang WU ZhiJun JIANG Lei TANG Song YAO HuiQiang | 2007 | Chinese Science Bulletin2007,52,3: | 6 |
| 4 | Microbe-related precipitation of iron and silica in the Edmond deep-sea hydrothermal vent field on the Central Indian Ridge显示文摘Microbial mats, several millimeters thick and brown-yellow to white in color, were collected in hollow inside of chimney structure from Edmond hydrothermal field on the Central Indian Ridge. Microbes with shapes of rod and helical stalk-like filaments were observed in the microbial mats, and are com- monly characterized by their cells completely encrusted by thick mineralized layers, made up of large amounts of amorphous silica and minor amounts of iron oxides. Transmission Electron Microscope observation has demonstrated that the acicular Fe-bearing matter was not only heterogenously dis- tributed on the surface of the cell wall, but also deposited in the inside of cell, suggesting that bio-precipitation of Fe had occurred both on the surface and in the interior of cell. Microbial silicification was also commonly found in the mats. Silica usually precipitated homogeneously on the surface of the microbes and forms micro-laminated layers, which might be controlled by the inorganic process of precipitation in hydrothermal environment. The biomineralization phenomenon in the mi- crobial mats showed that the precipitation of Fe and Si was closely related to microbes in hydrothermal environment. Considering that hydrothermal activities provided required chemical elements for miner- alization, it is suggested that this biomineralization process also might be driven by hydrothermal ac- tivities at the sea floor to some extent. | PENG XiaoTong ZHOU HuaiYang YAO HuiQiang LI diangTao TANG Song JIANG Lei WU ZiJun | 2007 | Chinese Science Bulletin2007,52,23: | 5 |
| 5 | Early-stage mineralization of hydrothermal tubeworms: New insights into the role of microorganisms in the process of mineralization显示文摘As an important part of marine hydrothermal system, hydrothermal vent faunas live in hydrothermal inorganic environment and closely interact with hydrothermal inorganic environment. Sometimes, they can participate in the mineralization process of modern hydrothermal site. Hydrothermal vent faunas, particularly vestimentiferan and polychaete tubeworms, are occasionally preserved in the geological record. Study on the early mineralization process of hydrothermal vent fauna is significant for under- standing the interaction between mineral and organism, and also the formation and preservation mechanism of geological fossil in hydrothermal environment. In this paper, the early stage of miner- alization of Vestimentiferan Ridgeia piscesae tubes collected from Juan de Fuca Ridge is studied. The results showed that a lot of filamentous microorganisms were unevenly distributed on the surface of internal wall and in the interspace of the wall of tubeworm. In some cases, microorganisms aggregated as thin layers in or on the wall of tubeworm. The surfaces of microbial cells and the products of micro- bial degradation may play an important role in the early mineralization of tubeworm. Semitransparent thin layers of organic matter containing sulfur and sulfur granules were commonly found on the wall of tubeworm with lower degree of mineralization. The degradation production of these semitransparent thin layers may accelerate the mineralization of tube wall during the early stage. EDS results showed that on the tube walls some chemical elements such as Fe, P, Ca and Si are selectively enriched from ambient hydrothermal environment. Interestingly, P, Ca and Si covary with Fe content. Because element S originated from the bio-oxidation of H2S by symbiotic microorganism in the tissue of tubeworm, it can be considered as a biomarker when studying the mineralization process of tube wall. Based on the characteristics of tubeworms with different degrees of mineralization, we suggested that the early mineralization stage of tube wall was mainly controlled by microbial-induced mineralization and the degradation process of tube wall. | PENG XiaoTong ZHOU HuaiYang TANG Song YAO HuiQiang JIANG Lei WU Zidun | 2008 | Chinese Science Bulletin2008,53,2: | 3 |

| 11 | Phosphorylation of the LCB1 subunit of Arabidopsis serine palmitoyltransferase stimulates its activity and modulates sphingolipid biosynthesis显示文摘Sphingolipids are the structural components of membrane lipid bilayers and act as signaling molecules in many cellular processes.Serine palmitoyltransferase(SPT)is the first committed and rate-limiting enzyme in the de novo sphingolipids biosynthetic pathway.The core SPT enzyme is a heterodimer consisting of LONG-CHAIN BASE1(LCB1)and LCB2 subunits.SPT activity is inhibited by orosomucoid proteins and stimulated by small subunits of SPT(ssSPTs).However,whether LCB1 is modified and how such modification might regulate SPT activity have to date been unclear.Here,we show that activation of MITOGEN-ACTIVATED PROTEIN KINASE 3(MPK3)and MPK6 by upstream MKK9 and treatment with Flg22(a pathogen-associated molecular pattern)increases SPT activity and induces the accumulation of sphingosine long-chain base t18:0 in Arabidopsis thaliana,with activated MPK3and MPK6 phosphorylating AtLCB1.Phosphorylation of AtLCB1 strengthened its binding with AtLCB2b,promoted its binding with ssSPTs,and stimulated the formation of higher order oligomeric and active SPT complexes.Our findings therefore suggest a novel regulatory mechanism for SPT activity. | Yuan Li Hanwei Cao Tingting Dong Xiaoke Wang Liang Ma Kun Li Huiqiang Lou Chun-Peng Song Dongtao Ren | 2023 | Journal of Integrative Plant Biology2023,65,6: | 0 |
