PAHs can negatively affect different aspects of plant growth and development. However, the mechanisms of PAHs effects and physiological response of plants to PAHs have not been adequately studied. Accordingly, the aim of this study was evaluation of the germination, growth and physiological responses of wheat, sunflower and alfalfa to phenanthrene toxicity. \u0000Material and Methods: This experiment was conducted as a pot culture of plants using a completely randomised design (CRD) with four replications. Plants were cultivated in soil containing 50 and 100 mg kg1 of phenanthrene for 14 days under greenhouse conditions. All biochemical assays were performed spectrophotometrically after the determination of growth parameters. \u0000Results: Soil contamination with phenanthrene differently decreased seed germination and the subsequent seedling growth of plants. Alfalfa showed the highest resistance at both the seed germination and seedling growth phases. Wheat and sunflower were the most sensitive species at the seed germination stage and seedling growth phase, respectively. Phenanthrene contamination induced oxidative stress in plants and POD was determined to be the important enzyme involved in ROS detoxification. \u0000Conclusions: Phenanthrene effects on seed germination, seedling growth and physiological parameters of plants are species-dependent. The induction of oxidative stress and decrease in photosynthetic pigments content are two of the reasons for lower plant growth in phenanthrenecontaminated soil, and POD was an important enzyme in the detoxification of ROS. At least in some species, the higher resistance at seed germination could be followed by the higher resistance of seedlings to PAHs.","PeriodicalId":11848,"journal":{"name":"Eurasian Journal of Biosciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70600817","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to determine the effect of various BAP (6- benzylaminopurine) concentrations on seed germination, shoot proliferation, and total hypericin in a tissue culture of Hypericum scabroides which is endemic to the Eastern Anatolia region, Turkey. \u0000Material and Methods: Hypericum scabroides specimens were collected from Eastern Anatolia (Elazig, Turkey). The effects of various BAP concentrations (0.0 (control), 0.5, 1.0, and 2.0 mg/L) on seed germination, shoot multiplication, and the accumulation of total hypericin were determined using tissue cultures of H. scabroides. Murashige and Skoog (MS) medium was used for germination and shoot cultures. Measurements of total hypericin were taken using a UV spectrophotometer. \u0000Results: The best germination rate (59.2%) was obtained using hormone-free MS medium (control group). Apical tips of freshly germinated seedlings were proliferated on the MS medium supplemented with various BAP concentrations (0.5, 1.0, and 2.0 mg/L) and the control group (without BAP). The highest number of shoots (42.7 shoot/explant) and longest shoot length (2.50 cm) were obtained on MS medium supplemented with 2.0 mg/L BAP. Total hypericin was found in trace amounts and it was found that the total hypericin was not affected by the concentration of BAP. \u0000Conclusions: Our results showed that increasing concentrations of BAP stimulated shoot multiplication but did not affect seed germination rates or total hypericin in in vitro cultures of H. scabroides.","PeriodicalId":11848,"journal":{"name":"Eurasian Journal of Biosciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70600471","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, L fusca is an attractive model plant to study the mechanism of salt tolerance mainly due to its characteristics as a typical euhalophyte, having both accumulating and excreting salt properties. Soil salinity adversely affects plant growth, development and disturbs intracellular ion homeostasis resulting cellular toxicity. The Salt Overly Sensitive 1 (SOS1) gene encodes a plasma membrane NaVH+ antiporter that plays an important role in imparting salt stress tolerance of plants. \u0000Material and Methods: Using conserved sequences of S O S 1 , the coding sequence of plasma membrane NaVH+ antiporter (SOS1) in kallar grass was partially isolated and its expression profile during salinity stress was investigated. \u0000Results: The aa (amino acid) sequence of the isolated region of /./SOS1 possesses the maximum identity up to 96% of its orthologue in Distichlis spicata. The results of semi-quantitative RT-PCR revealed that salinization was affected SOS1 transcript level positively. The expression of i./50S1 in leaves of kallar grass progressively increased under all salinity levels compared to control. \u0000Conclusions: The results suggest that i./SOS1 may play an essential role in the salt tolerance of L fusca and may be useful for improving salt tolerance in other crop species.","PeriodicalId":11848,"journal":{"name":"Eurasian Journal of Biosciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.5053/EJOBIOS.2015.9.0.2","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70600616","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The strain KG5 was identified by morphological, physiological, biochemical and 16S rRNA gene sequencing. The effects of various parameters on protease production, such as time, temperature, pH, carbon and nitrogen sources and CaCU were studied. The enzyme was purified by ammonium sulphate precipitation and Sephadex G-75 gel permeation chromatography. Molecular weight was calculated by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) and zymographic analysis. The effects of some metal ions, chelators and inhibitors on enzyme activity were determined. \u0000Results: The optimum temperature, pH and incubation period for protease production were 40-45°C, 7.0 and 24 h, respectively. It was determined that the best nitrogen sources were yeast extract and urea, while the best carbon sources were lactose and galactose. However, glucose as a source of carbon was found to inhibit the production of the enzyme. The maximum enzyme production was increased in the presence of CaCU. The molecular weight of purified enzyme was found to be approximately 48 kDa. It was found that the enzyme was fully stable in the presence of 2 mM CaCU at 50°C after 120 min. Purified protease was significantly activated by Ca2 + and Mg2 + , while it was greatly inhibited by Cu2 + , Zn2 + , Hg2 + and SDS as well as by the metal ion chelators ethylenediaminetetraacetic (EDTA) and 1,10-phenanthroline. Phenylmethylsulfonyl fluoride (PMSF) had a little effect on the enzyme. \u0000Conclusions: Our findings suggest the potential of this isolate for protease production and that this enzyme may be suitable for biotechnological applications.","PeriodicalId":11848,"journal":{"name":"Eurasian Journal of Biosciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70600767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study an approach was taken to identify the \u0000sources of such harmful antibiotics in the shrimp value chain of Bangladesh, one of the major shrimp countries. \u0000Material and Methods: Inputs of farms and hatchery systems including feed, feed additives, feed ingredients and therapeutic agents were thought to be the sources of contagion. Fish and shrimp feed, feed ingredients, sediment and water samples of shrimp hatcheries and farms were, therefore, analyzed for 3-Amino-5-morpholinomethyl-2-oxazolidinone (AMOZ), 3-Amino-2-oxazolidinone (AOZ), 1-Amino-hydantoin (AHD), Semicarbazide (SEM) and chloramphenicol (CAP) to identify their source and entry pathways. About 500 g of each 160 feed and feed ingredients were collected in pyrogens free polyethylene sealed bag and transported to Fish Inspection and Quality Control (FIQC) laboratory, Dhaka, Bangladesh.
