Increase uric acid levels have been found in oxidative stress. Urate radicals do not react with oxygen to form another peroxy radical, thus increasing the efficacy of uric acid as an antioxidant. Therefore, this study is designed to measure the level of uric acids and find out the relationship of uric acid with superoxide dismutase in induced hyperuricemic model. Forty male albino rats with an average weight of 180 ± 2 g were selected. The rats were grouped. The animals were fed on standard diet and given tap water ad libitum until treatment. Albino rats were divided into four groups. Group A(10)-control given only standard diet, group B(10) fed on 60% fructose with standard diet , group C(10) fed on fructose, standard diet and intraperitonially oxonic acid 250 mg/kg and group D (10) only on injection intraperotonially oxonic acid 250 mg/kg. At the end of study 10 mL of blood was drawn from heart of rats. Then blood was estimated for superoxide dismutase and uric acids done by kit methods randox-manual/Rx monza UA230/UA 233. Results: In Group C superoxide dismutase was found to be 32 % (244 mg/dL ± 2.23) more than control. In the same group the uric acid concentration was highly significantly correlated with control. Conclusion: The uric acid concentration increases when we take fructose up to 60% in our diet. It also increases superoxide dismutase concentration. More than this value may have inverse effect on the uric acid level and its role as an antioxidant may become inversed.

Pre-harvest sprouting in wheat is the germination of seeds within the spikes when rains occur after or during grain ripening, which occurs commonly in the barani tract of Pakistan. Therefore, 10 cultivars and five advanced lines of spring bread wheat were evaluated for pre-harvest sprouting resistance. After natural rainfall,seeds were immediately collected from the wet spikes and tested for germinating ability. Three different germination tests were applied to hand-threshed seed:(1) spikes threshed on the day of sampling and germination tested immediately,(2) spikes threshed on the day of sampling and germination tested 1 week later, and(3) spikes threshed 1 week after sampling and germination test immediately after threshing. Seeds and spikes kept for 1 week were place on blotting paper at room *** BARS-09, 09 FJ17, Doukkala-12, NARC-09 and Ouassou-20 exhibited higher sprouting resistance while other genotypes were susceptible to pre-harvest sprouting in each of the three tests. A diallel crossing was conducted with six susceptible and two resistant genotypes to assess the genetic behavior of pre-harvest sprouting *** combining ability(CA) demonstrated a higher proportion of additive genetic effects for sprouting resistance, because of higher variance of general and specific CA for both parameters under study. Doukkala-12 and BARS-09 showed increased pre-harvest sprouting resistance in their F1 descendants.

川西亚高山地区天然林向人工林的转换造成了土壤生态功能的退化,而细菌群落对土壤生态功能维持和提升有重要的调节作用;然而,关于天然林向人工林转换对土壤细菌群落及功能群影响的研究目前还比较缺乏.以川西亚高山云杉天然林和人工林为研究对象,采用高通量测序和Faprotax功能预测相结合的研究方法测定土壤细菌群落组成、多样性和功能群,分析森林转换对它们的影响,阐明驱动变化的关键因子.结果表明:云杉天然林土壤细菌群落的Shannon指数显著高于云杉人工林土壤,而Simpson指数显著低于人工林.主坐标分析(PCoA)显示天然林和人工林土壤细菌群落组成存在明显差异.两个林分共同拥有81.61%的OTUs数量,属水平上相对丰度大于1%的土壤细菌群落组成基本一致,共有23个属.其中慢生根瘤菌属(Bradyrhizobium)、Vicinamibacterales和KD4-96是两个森林类型中具有显著差异的优势属.通过功能预测分析发现,云杉人工林中化能异养作用、有氧化能异养作用和固氮作用优势细菌功能群的相对丰度显著高于天然林.冗余分析(RDA)结果表明土壤pH、含水率、全氮、铵态氮、微生物生物量氮是影响土壤细菌群落组成和功能群的主要因子.综上,川西亚高山云杉天然林向人工林转换显著影响土壤细菌群落多样性和组成,并提高了与碳氮循环相关的细菌功能群的相对丰度;上述研究结果可为深入理解森林转换对土壤生态功能的影响提供科学依据.

The main purpose of this paper is the sequence stratigraphy and biostratigraphy of lower Tertiary sediments on the base of larger benthic foraminifera in northeast of Iran (Chehel-Kaman Formation). This formation mainly consists of Limestone, dolomite and interbeds of sand, shale and evaporate sediments. Petrographical studies indicate that these sediments may have been deposited on a shallow carbonate platform ramp and consist of 4 carbonate lithofacies (15 subfacies). These lithofacies may have been deposited in open marine, shoal, lagoon and tidal flat environmental conditions. Sequence stratigraphy analysis led to identification of 4 third-order depositional sequences, bounded by type 2 (within the top of the underlying Pestehleigh Formation) and type 1 sequence boundaries (paleosol). Interpreted sea level curve in this basin can be relatively correlated with global curves during Paleocene time and a with a sea-level fall occurred in the latest Paleocene, followed by a rise in the earliest Eocene. Biostratigraphy study led to the identification of 32 larger benthic Foraminifera genera. The Paleocene/Eocene boundary has been probably recorded as a thin red paleosol horizon (~10 - 15 cm).

自1885年Frank首次提到菌根(mykorhiza)概念以来,大量的试验证实了丛枝菌根真菌(AMF)与植物根系之间形成具有一定结构和功能的共生体,促进植物生长并提高干旱耐受能力,在干旱生态系统中发挥重要的作用。该研究多集中在对宿主植物生理生态的影响及其机制方面,然而菌根共生对宿主植物水分吸收和信号产生、传递的影响研究少而分散,缺少系统总结。综述了最近四十多年丛枝菌根真菌与植物共生体对宿主植物干旱适应性影响研究进展,讨论了菌根共生对植物根冠通讯的影响及机理。干旱胁迫下AMF与植物共生,通过影响宿主植物一系列生理生态过程,提高宿主植物横向根压和纵向蒸腾拉力。经典的Ohm吸水模型是该方向最有代表性的研究成果,该模型揭示了菌根共生的根外菌丝具有不同于根细胞的细胞结构和水分运输性能,这为宿主植物提供一种特殊的快速吸水方式,可提高植物对土壤水分的吸收和运输能力。研究表明,AMF会影响宿主植物根冠通讯过程,如诱发信号级联反应,诱导根系尽早感知水分胁迫并产生非水力根源信号,提高宿主对干旱的耐受性。讨论了AMF在根冠通讯分子机制研究方面存在的问题及可能的解决途径,展望了AMF在干旱农业生产中的应用潜力。

Twelve wheat (Triticum aestivum L.) cultivars and their sixteen direct and reciprocal crosses were evaluated for heterosis, heterobeltiosis and potence ratio to determine the potential of wheat genotypes under contrasting water regimes. The highest positive heterosis and heterobeltiosis was observed in cross combination Sehr-06 × Pasban-90 under both water regimes for the trait stem reserve mobilization (SRM). While in trait 1000-grain weight the cross-combination Pari-73 × C-273 (Normal irrigation) and Fsd-08 × SA-42 (water stress) showed highest heterosis and Pari-73 × C-273(Normal irrigation) and Fsd-08 × Chenab-70(water stress) showed highest value of heterobeltiosis. The potence ratio in both traits expressed overdominance estimates exhibiting the presence of transgressive segregants, may be exploited for on-ward selection in the bread wheat improvement. The genotypes showing better SRM based 1000-grain weight in the absence of photosynthesis indicates relative water stress tolerance. This procedure paved an indirect way to screen the wheat genotypes to withhold water stress situation and sustain wheat production.

Objective: Artemisia annua is the chief source of artemisinin, a potent antimalarial agent, in which other bioactive phytochemicals are also present. Due to low levels of bioactive compounds including artemisinin and flavonoids, it is necessary to increase the level of the secondary metabolites by regulating the expression of rol genes in the ***: A hybrid variety of A. annua(Hyb1209 r, Shennong) developed by the Centre for Novel Agricultural Products, University of York, UK, was selected to produce transgenics of rolB and rolC genes. Genetic transformation was carried out via Agrobacterium tumefaciens GV3101 harboring rolB and rolC genes of Agrobacterium rhizogenes cloned separately. HPLC was used for the qualitative and quantitative analysis of flavonoids and artemisinin. Furthermore, thin layer chromatography(TLC) was also used to analyze artemisinin ***: Comparative analysis via HPLC revealed considerable enhancement in the phytochemical content of transgenic A. annua plants as compared to the wild type plant. Transgenics of rolB gene showed an average increase of 321% in rutin, 97.2% in caffeic acid, and 218.4% in myricetin, respectively. In the case of rolC gene transgenics, an average increase of 197.5% in rutin, 76.3% in caffeic acid, and 209.3%in myricetin was observed. Transgenics of rolB and rolC genes showed a 14.3%–28.6% and 2.8%–12.7% increase in artemisinin content respectively by HPLC analysis. TLC analysis showed that an average 142.2%and 110.2% enhancement in artemisinin for rolB and rolC transgenics respectively, compared with the wild type. An enhanced production of total flavonoids(average 30.2% and 25.5% increase in rolB and rolC transgenics, respectively) and total phenolics(average 34.3% and 25.8% increase in rolB and rolC transgenics, respectively) was observed as a result of transformation. Transformed A. annua plants showed improved free radical scavenging activity(average 46.5% and 29.1% increase in rolB and rolC tra
