Metabolomic Profiling in Selaginella lepidophylla at Various Hydration States Provides New Insights into the Mechanistic Basis of Desiccation Tolerance

Selaginella lepidophylla is one of only a few species of spike mosses （Selaginellaceae） that have evolved des-iccation tolerance （DT） or the ability to ＇resurrect＇ from an air-dried state. In order to understand the metabolic basis of DT, S, lepidophylla was subjected to a five-stage, rehydration/dehydration cycle, then analyzed using non-biased, global metabolomics profiling technology based on Gc/MS and UHLc/MS/MS2 platforms. A total of 251 metabolites including 167 named （66.5%） and 84 （33.4%） unnamed compounds were characterized. Only 42 （16.7%） and 74 （29.5%） of compounds showed significantly increased or decreased abundance, respectively, indicating that most compounds were produced con-stitutively, including highly abundant trehalose, sucrose, and glucose. Several glycolysis/gluconeogenesis and tricarboxylic acid （TcA） cycle intermediates showed increased abundance at 100% relative water content （RWc） and 50% RWc. Vanillate, a potent antioxidant, was also more abundant in the hydrated state. Many different sugar alcohols and sugar acids were more abundant in the hydrated state. These polyols likely decelerate the rate of water loss during the drying process as well as slow water absorption during rehydration, stabilize proteins, and scavenge reactive oxygen species （ROS）. In contrast, nitrogen-rich and y-glutamyl amino acids, citrulline, and nucleotide catabolism products （e.g. allantoin） were more abundant in the dry states, suggesting that these compounds might play important roles in nitrogen remobilization during rehydration or in ROS scavenging. UV-protective compounds such as 3-（3-hydroxyphenyl）propionate, apigenin, and naringenin, were more abundant in the dry states. Most lipids were produced constitutively, with the exception of choline phosphate, which was more abundant in dry states and likely plays a role in membrane hydration and stabilization. In contrast, several poly- unsaturated fatty acids were more abundant in the hydrated states, suggestin

Shaanxi 710075 China Department of Environmental Science and Engineering. xi'an Jiaotong University. Xi'an 710049. china Division of Atmospheric Sciences. Desert Research Institute. Reno. USA Hangzhou Municipal Environmental Monitoring center Hangzhou 310007 China

Aerosol observation was conducted for four seasons from September 2001 to August 2002 at five sampling sites in Hangzhou, South china, on PM10 mass, 22 elements （Na, Mg, AI, Si, P, S, K, ca, Ti, V, cr, Mn, Fe, Ni, cu, Zn, As. Se, Br, cd, Ba, and Pb）, 5 major ions （F^-, cl^ , NO3^-, SO4^2- , and NH4^＋）, and organic and elemental carbon （Oc and Ec）, showing that PM10 mass ranged from 46.7 to 270.8 μg/m^3, with an annual average of 119.2 μg/m^3. Na, AI, Si, S, K, ca, and Fe were the most abundant elements in PM10, most of S being in the form of SO4^2- . SO4^2-, NO3^-, and NH4^＋ were the major ions, which contributed to about 20% of the PM10 mass. The mean seasonal concentrations for SO4^2- , averaged over all sites, were found to be 18.0, 18.5, 24,Z and 21.4 μg/m^3, for spring, summer, autumn, and winter, respectively, while the corresponding loadings for NO3^- were 7.2, 4.7, 7.1, and 11.2 μg/m^3, and for NH4^＋ were 6.0, 5.9, 8.2, and 9.3 μg/m^3, in the form mostly of NH4NO3 in spring, autumn, and winter, and mostly of （NH4）2SO4 in summer. The low NO3^-/SO4^2- ratio found indicates coal combustion as the major source throughout the year. The mean annual concentrations of Oc and Ec in PM10 were found to be 21.4, and 4.1 μg/m^3, respectively. Material balance calculation indicated that fugitive dust, the secondary aerosol, and carbonaceous matter were the most abundant species in PM10 for the four seasons, as is characteristic for cities in South china.

Global Agricultural Trade and Developing countries

丛书名： Trade and Development Series

2005年

作者： Aksoy Mtaman Beghin john c.

ISBN: (纸本)0821358634

Global Agricultural Trade and Developing countries presents research findings based on a series of commodity studies of significant economic importance to developing countries. First, the book sets the stage with background chapters and investigations of cross-cutting issues. Trade and domestic policy regimes affecting agricultural and food markets are described, and the resulting patterns of production and trade are assessed. The book follows with an analysis of product standards and costs of compliance and their effects on agricultural and food trade. An investigation of the impact of preferences given to selected countries and their effectiveness is next. The evidence on the attempts to decouple agricultural support from agricultural output is then reviewed. The last background chapter explores the robustness of the global gains of multilateral agricultural and food trade liberalization. Given this context, the book presents detailed commodity studies for coffee, cotton, dairy, fruits and vegetables, groundnuts, rice, seafood products, sugar, and wheat. These markets feature distorted policy regimes among industrial or middle-income countries.; The studies analyze current policy regimes in key producing and consuming countries document the magnitude of these distortions and estimates the distributional impacts -winners and losers- of trade and domestic policy reforms. By bringing the key issues and findings together in one place, Global Agricultural Trade and Developing countries aids policy makers and researchers, both in their approach to global negotiations and in evaluating their domestic policies on agriculture. This book also complements the recently published Agriculture and the WTO that focuses primarily on the agricultural issues within the context of the WTO negotiations.

Thin-film composite (TFc) nanofiltration (NF) membranes were fabricated via the interfacial polymerization of piperazine (PIP) and 1,3,5-benzenetricart)oiiyl trichloride on polysulfone (PSf) support membranes blended with K^+-responsive poly(N-isopropylacryamideco- acryloylamidobenzo-15-crown-5)(P(NIPAM-co- AAB15c5)). Membranes were characterized by attenuated total reflection Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy, atomic force microscope, scanning electron microscope, contact angle, and filtration tests. The results showed that:(1) Under K^+-free conditions, the blended P(NIPAM-co-AAB15c5)/PSf supports had porous and hydrophilic surfaces, thereby producing NF membranes with smooth surfaces and low MgSO4 rejections;(2) With K^+ in the PIP solution, the surface roughness and water permeability of the resultant NF membrane were increased due to the K^+-induced transition of low-content P(NIPAM-co-AAB15c5) from hydrophilic to hydrophobic;(3) After a curing treatment at 95℃, the improved NF membrane achieved an even higher pure water permeability of 10.97 L·m^-2·h^-1 - bar1 under 200 psi. Overall, this study provides a novel method to improve the performance of NF membranes and helps understand the influence of supports on TFc membranes.

Selective catalytic reduction （ScR） of NOx with NH3 is an effective technique to remove NOx from stationary sources, such as coal-fired power plant and industrial boilers. Some of elements in the fly ash deactivate the catalyst due to strong chemisorptions on the active sites. The poisons may act by simply blocking active sites or alter the adsorption behaviors of reactants and products by an electronic interaction. This review is mainly focused on the chemical poisoning on V2O5-based catalysts, environmental-benign catalysts and low temperature catalysts. Several common poisons including alkali/alkaline earth metals, SO2 and heavy metals etc. are referred and their poisoning mechanisms on catalysts are discussed. The regeneration methods of poisoned catalysts and the development of poison-resistance catalysts are also compared and analyzed. Finally, future research directions in developing poisoning resistance catalysts and facile efficient regeneration methods for ScR catalysts are proposed.
