| 1 | 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.

| 2 | Enhanced and irreversible sorption of pesticide pyrimethanil by soil amended with biochars显示文摘Biochar derived from partial combustion of vegetation is ubiquitous and potentially effective in sequestration of environmental contaminants.Biochars were prepared by burning of red gum(Eucalyptus spp.) woodchips at 450 and 850°C(labeled as BC450 and BC850).These two biochars were found to possess markedly different properties in terms of surface area and porosity.Short-term equilibration tests(24 hr) were conducted to assess the sorption-desorption behavior of pyrimethanil in the soil amended with various amounts of biochar of each type,with a special focus on the desorption behavior of the sorbed pesticide through four times successive desorption by dilution.Sorption coefficient and isotherm nonlinearity of the amended soils progressively increased with the content of biochar in the soil.Biochar BC850 with higher surface area and microporosity showed a stronger effect on the reversibility of sorption pesticide.The soils amended with 5% BC450 and 1% BC850 had nearly the same sorption capacity for pyrimethanil;however,their desorption processes were very different with 13.65% and 1.49% of the sorbed pesticide being released,respectively.This study suggested that biochar in soil could be an important factor for immobilization of a pesticide and thus affecting its environment fate in soil. | Xiangyang Yu Ligang Pan Guangguo Ying Rai S.

| 3 | Analysis of soil moisture variation by forest cover structure in lower western Himalayas, India显示文摘Soil moisture affects various hydrological processes, including evapotranspiration, infiltration, and runoff. Forested areas in the lower western Himalaya in India constitute the headwater catchments for many hill streams and have experienced degradation in forest cover due to grazing, deforestation and other human activities. This change in forest cover is likely to alter the soil moisture regime and, consequently, flow regimes in streams. The effect of change in forest cover on soil moisture regimes of this dry region has not been studied through long term field observations. We monitored soil matric potentials in two small watersheds in the lower western Himalaya of India. The watersheds consisted of homogeneous land covers of moderately dense oak forest and moderately degraded mixed oak forest. Observations were recorded at three sites at three depths in each watershed at fortnightly intervals for a period of three years. The soil moisture contents derived from soil potential measurements were analyzed to understand the spatial, temporal and profile variations under the two structures of forest cover. The analysis revealed large variations in soil moisture storage at different sites and depths and also during different seasons in each watershed. Mean soil moisture storage during monsoon, winter and summer seasons was higher under dense forest than under degraded forest. Highest soil moisture content occurred at shallow soil profiles, decreasing with depth in both watersheds. A high positive correlation was found between tree density and soil moisture content. Mean soil moisture content over the entire study period was higher under dense forest than under degraded forest. This indicated a potential for soil water storage under well managed oak forest. Because soil water storage is vital for sustenance of low flows, attention is needed on the management of oak forests in the Himalayan region. | J. V. Tyagi Nuzhat Qazi S. P. Rai M. P.

| 4 | Seasonal Inhomogeneity of Soot Particles over the Central Indo-Gangetic Plains,India:Influence of Meteorology显示文摘Black carbon(BC) particles play a unique and important role in earth's climate system.BC was measured(in-situ) in the central part of the Indo-Gangetic Plains(IGP) at Varanasi,which is a highly populated and polluted region due to its topography and extensive emission sources.The annual mean BC mass concentration was 8.92 ± 7.0 μg m^(-3),with 34%of samples exceeding the average value.Seasonally,BC was highest during the post-monsoon and winter periods(approximately 18 μg m^(-3)) and lower in the premonsoon/monsoon seasons(approximately 6 μg m^(-3)).The highest frequency(approximately 46%) observed for BC mass was in the interval from 5 to 10 μg m^(-3).However,during the post-monsoon season,the most common values(approximately 23%) were between 20 and 25 μg m^(-3).The nighttime concentrations of BC were approximately twice as much as the daytime values because of lower boundary layer heights at nighttime.The Angstrom exponent was significantly positively correlated(0.55) with ground-level BC concentrations,indicating the impact of BC on the columnar aerosol properties.The estimated mean absorption Angstrom exponent was 1.02 ± 0.08 μg m^(-3),indicating that the major source of BC was from fossil fuel combustion.Significant negative correlations between BC mass and meteorological parameters indicate a pronounced effect of atmospheric dynamics on the BC mass in this region.The highest mean BC mass concentration(18.1 ± 6.9 μg m^(-3)) as a function of wind speed was under calm wind conditions(38%of the time). | SINGH B.P.
