| 1 | Contributions of phosphatase and microbial activity to internal phosphorus loading and their relation to lake eutrophication显示文摘Phosphatase may accelerate the process of lake eutrophication through improving phosphorus bioavailability. This mechanism was studied in three Chinese eutrophic shallow lakes (Lake Taihu, Lake Longyang and Lake Lianhua). Phosphatase activity was related to the concentration of soluble reactive phosphorus (SRP) and chlorophyll a. Stability of dissolved phosphatase in reverse micelles may be attributed to molecular size, conformation and active residues of the enzyme.At the site with Microcystis bloomed in Lake Taihu, dissolved phosphatase activity was higher and more stable in micelles, SRP concentrations were lower in interstitial water, the contents of different forms of phosphorus and the amounts of aerobic bacteria were lower while respiration efficiency was higher in sediments. Phosphobacteria, both inorganic and organic and other microorganisms were abundant in surface water but rare in sediments. Therefore, internal phosphorus may substantially flux into water column by enzymatic hydrolysis and anaerobic release, together with mobility of bacteria,thereby initiating the bloom. In short, biological mechanism may act in concert with physical and chemical factors to drive the internal phosphorus release and accelerate lake eutrophication. | SONG Chunlei, CAO Xiuyun, LI Jianqiu, LI Qingman, CHEN Guoyuan & ZHOU Yiyong Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan 430072, China Graduate School of the Chinese Academy of Sciences, Beijing 100039, China | 2006 | Science China Earth Sciences2006，49，z1： | 5 |
| 2 | Identification of long noncoding RNAs involved in resistance to downy mildew in Chinese cabbage显示文摘Brassica downy mildew,a severe disease caused by Hyaloperonospora brassicae,can cause enormous economic losses in Chinese cabbage(Brassica rapa L.ssp.pekinensis)production.Although some research has been reported recently concerning the underlying resistance to this disease,no studies have identified or characterized long noncoding RNAs involved in this defense response.In this study,using high-throughput RNA sequencing,we analyzed the disease-responding mRNAs and long noncoding RNAs in two resistant lines(T12–19 and 12–85)and one susceptible line(91–112).Clustering and Gene Ontology analysis of differentially expressed genes(DEGs)showed that more DEGs were involved in the defense response in the two resistant lines than in the susceptible line.Different expression patterns and proposed functions of differentially expressed long noncoding RNAs among T12–19,12–85,and 91–112 indicated that each has a distinct disease response mechanism.There were significantly more cis-and trans-functional long noncoding RNAs in the resistant lines than in the susceptible line,and the genes regulated by these RNAs mostly participated in the disease defense response.Furthermore,we identified a candidate resistance-related long noncoding RNA,MSTRG.19915,which is a long noncoding natural antisense transcript of a MAPK gene,BrMAPK15.Via an agroinfiltration-mediated transient overexpression system and virus-induced gene silencing technology,BrMAPK15 was indicated to have a greater ability to defend against pathogens.MSTRG.19915-silenced seedlings showed enhanced resistance to downy mildew,probably because of the upregulated expression of BrMAPK15.This research identified and characterized long noncoding RNAs involved in resistance to downy mildew,laying a foundation for future in-depth studies of disease resistance mechanisms in Chinese cabbage. | Bin Zhang Tongbing Su Peirong Li Xiaoyun Xin Yunyun Cao Weihong Wang Xiuyun Zhao Deshuang Zhang Yangjun Yu Dayong Li Shuancang Yu Fenglan Zhang | 2021 | Horticulture Research2021，8，1： | 3 |
| 3 | Nutrients regeneration pathway, release potential, transformation pattern and algal utilization strategies jointly drove cyanobacterial growth and their succession显示文摘In order to better understand the contribution of nutrients regeneration pathway, release potential and transformation pattern to cyanobacterial growth and succession, 7 sampling sites in Lake Chaohu with different bloom degree were studied every two months from February to November 2018. The carbon, nitrogen(N) and phosphorus(P) forms or fractions in surface, interstitial water and sediments as well as extracellular enzymatic activities, P sorption, specific microbial abundance and community composition in sediments were analyzed. P regeneration pathway was dominated by iron-bound P desorption and phosphorus-solubilizing bacteria solubilization in severe-bloom and slight-bloom area respectively, which both resulted in high soluble reactive phosphorus(SRP) accumulation in interstitial water. However, in severe-bloom area, higher P release potential caused the strong P release and algal growth, compared to slight-bloom area. In spring, P limitation and N selective assimilation of Dolichospermum facilitated nitrate accumulation in surface water, which provided enough N source for the initiation of Microcystis bloom. In summer, the accumulated organic N in Dolichospermum cells during its bloom was re-mineralized as ammonium to replenish N source for the sustainable development of Microcystis bloom. Furthermore, SRP continuous release led to the replacement of Dolichospermum by Microcystis with the advantage of P quick utilization, transport and storage. Taken together, the succession from Dolichospermum to Microcystis was due to both the different forms of N and P in water column mediated by different regeneration and transformation pathways as well as release potential, and algal N and P utilization strategies. | Hui Li Chunlei Song Liu Yang Hangdao Qin Xiuyun Cao Yiyong Zhou | 2021 | Journal of Environmental Sciences2021，33，5： | 2 |

| 11 | Cyanobacterial extracellular alkaline phosphatase:detection and ecological function显示文摘Dissolved inorganic phosphorus is an important form of directly bioavailable phosphorus for cyanobacteria in natural water.Dissolved organic phosphorus could be used by cyanobacteria via alkaline phosphatase,which is produced mainly by bacteria and also cyanobacteria itself.Herein,we review the current knowledge of extracellular phosphatase excreted by cyanobacteria,highlighting the development of detection method and its ecological roles in regulating pho sphorus cycling in freshwater systems,which is based on reports for around 100 species of cyanobacteria.Recommendations are suggested concerning the extracellular phosphatase produced by bloom-forming cyanobacteria in terms of the ecological role,followed by a discussion of the future prospects for the study. | Lingling WAN Chunlei SONG Yiyong ZHOU Xiuyun CAO | 2022 | Journal of Oceanology and Limnology2022，40，5： | 0 |
| 12 | LEDGE STRUCTURE ON BROAD FACES OF FERRITE PLATES IN LOWER BAINITE显示文摘The ferrite/austenite interfacial structure in lower bainite has been studied in ahypereutectoid steel by means of electron microscopy.It is found that the mobile growthledges and superledges and their three-dimensional morphologies exist on the broad faces offerrite plates.Structural ledges were also observed on the broad faces of lower bainite.Basedon TEM observations,the viewpoint that the growth ledges can also evolve from structuralledges is proposed.These observations provide evidences to the ledge growth mechanism oflower bainite. | JIN Qiang FANG Hongsheng CAO Jianjun ZHENG Yankang CHEN Xiuyun Tsinghua University,Beijing,China Present adress: Central Iron and Steel Research Institute,Ministry of Metallurgical Industry,Beijing,100081,China | 1991 | Acta Metallurgica Sinica(English Letters)1991，4，3： | 0 |
