| 1 | Estimation of As and Cu Contamination in Agricultural Soils Around a Mining Area by Reflectance Spectroscopy:A Case Study显示文摘Concentrations of Iron (Fe), As, and Cu in soil samples from the fields near the Baoshan Mine in Hunan Province, China, were analyzed and soil spectral reflectance was measured with an ASD FieldSpec FR spectroradiometer (Analytical Spectral Devices, Inc., USA) under laboratory condition. Partial least square regression (PLSR) models were constructed for predicting soil metal concentrations. The data pre-processing methods, first and second derivatives (FD and SD), baseline correction (BC), standard normal variate (SNV), multiplicative scatter correction (MSC), and continuum removal (CR), were used for the spectral reflectance data pretreatments. Then, the prediction results were evaluated by relative root mean square error (RRMSE) and coefficients of determination (R 2 ). According to the criteria of minimal RRMSE and maximal R 2 , the PLSR models with the FD pretreatment (RRMSE = 0.24, R 2 = 0.61), SNV pretreatment (RRMSE = 0.08, R 2 = 0.78), and BC-pretreatment (RRMSE = 0.20, R 2 = 0.41) were considered as the final models for predicting As, Fe, and Cu, respectively. Wavebands at around 460, 1 400, 1 900, and 2 200 nm were selected as important spectral variables to construct final models. In conclusion, concentrations of heavy metals in contaminated soils could be indirectly assessed by soil spectra according to the correlation between the spectrally featureless components and Fe; therefore, spectral reflectance would be an alternative tool for monitoring soil heavy metals contamination. | REN Hong-Yan ZHUANG Da-Fang A.

| 2 | Heteromeric and Homomeric Geranyl Diphosphate Synthases from Catharanthus roseus and Their Role in Monoterpene Indole Alkaloid Biosynthesis显示文摘Catharanthus roseus 是二很重要的 monoterpene 吲哚碱(MIA ) 的唯一的来源反癌症代理人:vinblastine 和长春新碱。MIA 拥有萜烯和分别地从 terpenoid 和 shikimate 小径导出的吲哚一半。Geranyl diphosphate (GPP ) ,入口点到萜烯一半的形成,由 GPP synthase (GPPS ) 是 isopentenyl diphosphate (IPP ) 和 dimethylallyl diphosphate (DMAPP ) 的冷凝作用的一个产品。这里,我们报导与顺序类似编码蛋白质到大子单元(CrGPPS.LSU ) 和 heteromeric GPPS,和 homomeric 的小子单元(CrGPPS.SSU ) 的三基因 GPPS。CrGPPS.LSU 是生产 GPP 和 geranyl geranyl diphosphate (GGPP ) 的 bifunctional 酶, CrGPPS.SSU 是不活跃的,而 CrGPPS 是形成 GPP 的 homomeric 酶。在 Escherichia coli 的两个子单元的合作表示与生产仅仅 GPP 的提高的活动导致了 heteromeric 酶。当 CrGPPS.LSU 和 CrGPPS 在更旧、更年轻的叶子显示出更高的表示时,分别地, CrGPPS.SSU 显示出一个增加的趋势并且逐渐地减少了。叶子的甲基 jasmonate (MeJA ) 处理显著地导致了仅仅 CrGPPS.SSU 的表示。而 CrGPPS 是 mitochondrial, GFP 本地化显示 CrGPPS.SSU 是 plastidial。在 C 的 AmGPPS.SSU 的短暂 overexpression。roseus 叶子导致了增加的 vindoline, vinblastine 和长春新碱的立即的 monomeric 先锋。尽管 C。roseus 有 heteromeric 和 homomeric GPPS 酶,我们的结果含有有为 MIA 生合成调整 GPP 流动的 CrGPPS.SSU 的仅仅 heteromeric GPPS 的参与。 | Avanish Rai Shachi S.

| 3 | 赤霉素对甘蔗发芽和早期蔗茎生长的潜在调节作用(英文)显示文摘以甘蔗品种CoSe92423单芽为材料,在盘栽条件下研究赤霉素(GA3)对甘蔗生长特点和生化特性的影响。将甘蔗单芽分别浸入10,20,50和100mg·L-1赤霉素溶液中24h,以清水为对照,将处理的芽段种植于网室泥盘中。结果表明,低水平GA3处理(10,20,和50mg·L-1)均可刺激蔗芽生长和甘蔗植株的生长,根数、根和叶片鲜重、蔗茎鲜重、叶面积以及茎长均有所增加。与对照相比(70%),赤霉素可使蔗芽萌发早,发芽率高,其中以50mg·L-1GA3处理的发芽率最高,为90%。经赤霉素处理的甘蔗株高和茎重分别增加90%~110%、252%~282%,其中以20mg·L-1GA3处理最高。此外,赤霉素处理的蔗芽中还原糖和IAA含量也有所增加,且均以20mg·L-1GA3处理最高。因此,低水平赤霉素均对蔗芽萌发和生长具有刺激作用,但高水平赤霉素则对甘蔗生长有抑制作用。 | Radha Jain S.

| 6 | Organic Ligand,Competing Cation,and pH Effects on Dissolution of Zinc in Soils显示文摘A series of experiments were conducted to examine the interactive effects of an organic ligand,a competing cation, and pH on the dissolution of zinc (Zn) from three California soils,Maymen sandy loam,Merced clay,and Yolo clay loam.The concentrations of soluble Zn of the three soils were low in a background solution of Ca(NO3)2.Citric acid,a common organic ligand found in the rhizosphere,was effective in mobilizing Zn in these soils;its presence enhanced the concentration of Zn in soil solution by citrate forming a complex with Zn.The ability of Zn to form a complex with citric acid in the soil solution was dependent on the concentration of citric acid,pH,and the concentration of the competing cation Ca^(2+).The pH of the soil solution determined the extent of desorption of Zn in solid phase in the presence of citric acid.The amounts of Zn released from the solid phase were proportional to the concentration of citric acid and inversely proportional to the concentration of Ca(NO3)2 background solution,which supplied the competing cation Ca^(2+) for the formation of a complex with citrate.When the soil suspension was spiked with Zn,the adsorption of Zn by the soils was retarded by citric acid via the formation of the soluble Zn-citrate complex.The dissolution of Zn in the presence of citric acid was pH dependent in both adsorption and desorption processes. | P.
