The genetic potential to produce hydroxyatrazine was previously attributed to a 1.9-kb AvaI DNA fragment from strain ADP (M. L. de Souza, L. P. Wackett, K. L. Boundy-Mills, R. T. Mandelbaum, and M. J. Sadowsky, Appl. Environ. Microbiol. 61:3373–3378, 1995). In this study, sequence analysis of the 1.9-kb AvaI fragment indicated that a single open reading frame, atzA, encoded an activity transforming atrazine to hydroxyatrazine. The open reading frame for the chlorohydrolase was determined by sequencing to be 1,419 nucleotides and encodes a 473-amino-acid protein with a predicted subunit molecular weight of 52,421. The deduced amino acid sequence matched the first 10 amino acids determined by protein microsequencing. The protein AtzA was purified to homogeneity by ammonium sulfate precipitation and anion-exchange chroma- tography. The subunit and holoenzyme molecular weights were 60,000 and 245,000 as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and gel filtration chromatography, respectively.

  • Atrazine Mineralization Potential and Catabolic Gene Detection In
    ATRAZINE MINERALIZATION POTENTIAL AND CATABOLIC GENE DETECTION IN AGRICULTURAL AND WETLAND SITES DISSERTATION Presented in Partial Fulfillment of the Requirements of the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Kristen Lynn Anderson, B. S. * * * * * The Ohio State University 2003 Dissertation Committee: Approved by Dr. Olli H. Tuovinen, Advisor Dr. Michael J. Boehm _____________________________ Dr. Mark Morrison Advisor Dr. Samuel J. Traina Department of Microbiology ABSTRACT Atrazine (2-chloro-4-ethylamine-6-isopropylamino-1,3,5 triazine) is a commonly applied herbicide in corn fields. Although the fate of atrazine in agricultural systems has been well studied, the environmental fate of atrazine in wetland systems is less well characterized. The majority of research in this area has focused on aerobic mineralization of atrazine, although anaerobic conditions are commonly found in wetland sediments and bulk soils associated with agricultural fields. The hypothesis for this work was that atrazine would be actively mineralized in agricultural and wetland sites. It was further hypothesized that active mineralization in soils could be correlated with the presence of selected genes involved in atrazine metabolism. Soil, sediment, and water samples were obtained from three sites in Ohio. Atrazine mineralization was investigated under aerobic and anaerobic conditions in these samples using a biometer system in 14 which CO2 evolution was correlated with atrazine mineralization. All samples mineralized atrazine under aerobic conditions. Under anaerobic conditions, some external electron acceptor amendments inhibited mineralization, while others enhanced it. The effect on mineralization varied with the sample and season. Attempts were made to amplify some of the genes involved in atrazine mineralization.

  • Proteomic Analysis of the Response of Funnelifor Mismosseae/Medicago Sativa to Atrazine Stress Xin Sui1,2† ,Qiwu1,2†, Wei Chang1,2, Xiaoxu Fan1,2 and Fuqiang Song1,2*
    Sui et al. BMC Plant Biology (2018) 18:289 https://doi.org/10.1186/s12870-018-1492-1 RESEARCH ARTICLE Open Access Proteomic analysis of the response of Funnelifor mismosseae/Medicago sativa to atrazine stress Xin Sui1,2† ,QiWu1,2†, Wei Chang1,2, Xiaoxu Fan1,2 and Fuqiang Song1,2* Abstract Background: Arbuscular mycorrhizal (AM) fungi form symbiotic associations with host plants can protect host plants against diverse biotic and abiotic stresses, and promote biodegradation of various contaminants. However, the molecular mechanisms of how the arbuscular mycorrhizal fungi and host plant association on atrazine stress were still poorly understood. To better characterize how arbuscular mycorrhizal fungi and host plant interactions increase atrazine stress, we performed physiological and proteomic analysis of Funneliformis mosseae (mycorrhizal fungi) and Medicago sativa (alfalfa) association under atrazine stress. Results: The results showed that in the Arbuscular mycorrhizal, protective enzymes were up regulated and the malondialdehyde content increased relative to those of non-mycorrhizal M.sativa. We also examined the atrazine degradation rates within the nutrient solution, and a 44.43% reduction was observed with the mycorrhizal M.sativa, with 30.83% of the reduction attributed to F. mosseae. The accumulation content in root and stem of mycorrhizal M.sativa were obviously increased 11.89% and 16.33% than those of non- mycorrhizal M.sativa. The activity of PPO, POD, CAT and SOD in mycorrhizal M.sativa were obviously higher than non mycorrhizal M.sativa under atrazine stess. We identified differential root proteins using isobaric tags for relative and absolute quantization coupled with liquid chromatography–mass spectrometry, with 533 proteins identified (276 unregulated and 257 downregulated).

Therefore, and because of its ecotoxicological properties, its use has been forbidden in most European countries, including Portugal. However, atrazine is still used in many countries worldwide. The main purpose of the present work was to examine the efficacy of the atrazine- degrading bacteria Pseudomonas sp. ADP ( P. ADP) as bioaugmentation agent in soils contaminated with high doses (~20x and ~50xRD; RD – Recommended dose) of the commercial formulation, Primextra S-Gold, that contains atrazine, and also S-metolachlor and benoxacor as main active ingredients. It was also tested the effect of combining bioaugmentation and biostimulation using soil amendment with trisodium citrate in open soil microcosms, with the purpose of scaling-up this bioremediation tool.

Agrochemicals refer to a broad range of insecticides, fungicides and herbicides, and among them stands out atrazine, a herbicide intensively used in sugarcane, corn and sorghum cultures, among others. Researches have demonstrated that atrazine has toxic effects in algae, aquatic plants, aquatic insects, fishes and mammals. Due to the toxicity and persistence of atrazine in the environment, the search of microbial strains capable of degrading it is fundamental to the development of bioremediation processes, as corrective tools to solve the current problems of the irrational use of agrochemicals. This review relates the main microbial aspects and research on atrazine degradation by isolated microbial species and microbial consortia, as well as approaches on the development of techniques for microbial removal of atrazine in natural environments. Key words : atrazine, biodegradation, bacteria, fungi, microbial consortium INTRODUCTION thus, inhibiting the photosynthetic electron transport.

    Expression of Anti-Atrazine scFv and Atrazine Chlorohydrolase TrzN in planta for Potential Phytoremediation of Atrazine Contamination By Siripen Leelachao A Thesis Presented to The University of Guelph In partial fulfilment of requirements for the degree of Degree of Doctor of Philosophy In Environmental Biology and Toxicology Guelph, Ontario, Canada © Siripen Leelachao, April, 2015 ABSTRACT EXPRESSION OF ANTI-ATRAZINE SCFV AND ATRAZINE CHLOROHYDROLASE TRZN IN PLANTA FOR POTENTIAL PHYTOREMEDIATION OF ATRAZINE CONTAMINATION Siripen Leelachao Advisors: University of Guelph, 2014 Professor J. Christopher Hall Professor Keith R. Solomon Atrazine is extensively used in agricultural production to improve crop yield throughout North America. Due to contamination of surface water with atrazine, which is an environmental concern, tools for mitigating such contamination are needed. In this study, the potential use of genetically modified plants for remediation of atrazine contamination was investigated. Plants were genetically modified to express proteins of interest using Agrobacterium-mediated transformation. First, an anti-atrazine single chain variable fragment (scFv) was expressed in Lemna minor. In a hydroponic system, transgenic L. minor expressing the scFv showed higher tolerance to atrazine than wild- type plants. Absorption of 14C-atrazine in transgenic L. minor was greater than wild-type L. minor. Metabolites of atrazine were not found in transgenic L. minor. Second, L. minor was transformed to express atrazine chlorohydrolase (TrzN), but the protein could not be detected. Resistance to atrazine was found in the transgenic plants at low concentrations. Finally, the gene of atrazine chlorohydrolase TrzN was tested in Nicotiana Benthamiana by agroinfiltration. Transient Expression of atrazine ii chlorohydrolase TrzN and tolerance to atrazine in transgenic N.

Correspondence: Lawrence P. Wackett ([email protected]) Biodegradation is simply the metabolism of anthropogenic, or otherwise unwanted, che- micals in our environment, typically by microorganisms. The metabolism of compounds commonly found in living things is limited to several thousand metabolites whereas ∼100 million chemical substances have been devised by chemical synthesis, and ∼100 000 are used commercially. Since most of those compounds are not natively found in living things, and some are toxic or carcinogenic, the question arises as to whether there is some organism somewhere with the enzymes that can biodegrade them. Repeatedly, anthropogenic chemicals have been denoted ‘non-biodegradable,’ only to find they are reactive with one or more enzyme(s). Enzyme reactivity has been organized into categor- ies of functional group transformations. The discovery of new functional group transfor- mations has continually expanded our knowledge of enzymes and biodegradation. This expansion of new-chemical biodegradation is driven by the evolution and spread of newly evolved enzymes.

  • Enhanced Atrazine Degradation: Evidence for Reduced Residual Weed Control and a Method for Identifying Adapted Soils and Predicting Herbicide Persistence L
    Weed Science 2009 57:427–434 Enhanced Atrazine Degradation: Evidence for Reduced Residual Weed Control and a Method for Identifying Adapted Soils and Predicting Herbicide Persistence L. Jason Krutz, Ian C. Burke, Krishna N. Reddy, Robert M. Zablotowicz, and Andrew J. Price* Soilborne bacteria with novel metabolic abilities have been linked with enhanced atrazine degradation and complaints of reduced residual weed control in soils with an s-triazine use history. However, no field study has verified that enhanced degradation reduces atrazine’s residual weed control. The objectives of this study were to (1) compare atrazine persistence and prickly sida density in s-triazine-adapted and nonadapted field sites at two planting dates; (2) utilize original and published data to construct a diagnostic test for identifying s-triazine-adapted soils; and (3) develop and validate an s- triazine persistence model based on data generated from the diagnostic test, i.e., mineralization of ring-labeled 14C-s- triazine. Atrazine half-life values in s-triazine-adapted soil were at least 1.4-fold lower than nonadapted soil and 5-fold lower than historic estimates (60 d). At both planting dates atrazine reduced prickly sida density in the nonadapted soils (P # 0.0091). Conversely, in the s-triazine-adapted soil, prickly sida density was not different between no atrazine PRE and atrazine PRE at the March 15 planting date (P 5 0.1397). A lack of significance in this contrast signifies that enhanced degradation can reduce atrazine’s residual control of sensitive weed species. Analyses of published data indicate that cumulative mineralization in excess of 50% of C0 after 30 d of incubation is diagnostic for enhanced s-triazine degradation.

Expanding the Enzyme Universe: Accessing Non-Natural Reactions by Mechanism-Guided Directed Evolution Dr. Hans Renata, Dr. Z. Jane Wang, and Prof. Dr. Frances H. Arnold Division of Chemistry and Chemical Engineering, California Institute of Technology, 1200 E. California Blvd. MC 210-41, Pasadena, CA 91125 (USA) Frances H. Arnold: [email protected] Abstract High selectivities and exquisite control over reaction outcomes entice chemists to use biocatalysts in organic synthesis. However, many useful reactions are not accessible because they are not in nature’s known repertoire. We will use this review to outline an evolutionary approach to engineering enzymes to catalyze reactions not found in nature. We begin with examples of how nature has discovered new catalytic functions and how such evolutionary progressions have been recapitulated in the laboratory starting from extant enzymes. We then examine non-native enzyme activities that have been discovered and exploited for chemical synthesis, emphasizing reactions that do not have natural counterparts. The new functions have mechanistic parallels to the native reaction mechanisms that often manifest as catalytic promiscuity and the ability to convert from one function to the other with minimal mutation. We present examples of how non-natural activities have been improved by directed evolution, mimicking the process used by nature to create new catalysts.
