Heterologous Expression and Identification of the Genes Involved
Heterologous Expression and Identification of the Genes Involved in Anaerobic Degradation of 1,3-Dihydroxybenzene (Resorcinol) in Azoarcus anaerobiusᰔ Paula I. Darley,1† Jutta A. Hellstern,1†‡ Javier I. Medina-Bellver,2 Silvia Marque´s,2 Bernhard Schink,1 and Bodo Philipp1* Fachbereich Biologie, Universita¨t Konstanz, D-78457 Constance, Germany,1 and Estacio´n Experimental del Zaidı´n, C/. Profesor Albareda 1, E-18008 Granada, Spain2 Received 9 November 2006/Accepted 9 March 2007 Azoarcus anaerobius, a strictly anaerobic, gram-negative bacterium, utilizes resorcinol as a sole carbon and energy source with nitrate as an electron acceptor. Previously, we showed that resorcinol degradation by this bacterium is initiated by two oxidative steps, both catalyzed by membrane-associated enzymes that lead to the formation of hydroxyhydroquinone (HHQ; 1,2,4-benzenetriol) and 2-hydroxy-1,4-benzoquinone (HBQ). This study presents evidence for the further degradation of HBQ in cell extracts to form acetic and malic acids. To identify the A. anaerobius genes required for anaerobic resorcinol catabolism, a cosmid library with genomic DNA was constructed and transformed into the phylogenetically related species Thauera aromatica, which cannot grow with resorcinol. By heterologous complementation, a transconjugant was identified that gained the ability to metabolize resorcinol. Its cosmid, designated R؉, carries a 29.88-kb chromosomal DNA fragment containing 22 putative genes. In cell extracts of T. aromatica transconjugants, resorcinol was degraded to HHQ, HBQ, and acetate, suggesting that cosmid R؉ carried all of the genes necessary for resorcinol degradation. On the basis of the physiological characterization of T. aromatica transconjugants carrying transposon insertions -in different genes of cosmid R؉, eight open reading frames were found to be essential for resorcinol miner alization. -

Pieper, Ramón Rosselló-Móra, Jesús Sánchez, Jana Seifert and Manuel Ferrer 10 Supporting Online Material includes Text (Supporting Materials and Methods) Tables S1 to S9 Figures S1 to S7 1 SUPPORTING TEXT Supporting Materials and Methods Soil characterisation Soil pH was measured in a suspension of soil and water (1:2.5) with a glass electrode, and 5 electrical conductivity was measured in the same extract (diluted 1:5). Primary soil characteristics were determined using standard techniques, such as dichromate oxidation (organic matter content), the Kjeldahl method (nitrogen content), the Olsen method (phosphorus content) and a Bernard calcimeter (carbonate content). The Bouyoucos Densimetry method was used to establish textural data. Exchangeable cations (Ca, Mg, K and 10 Na) extracted with 1 M NH 4Cl and exchangeable aluminium extracted with 1 M KCl were determined using atomic absorption/emission spectrophotometry with an AA200 PerkinElmer analyser. The effective cation exchange capacity (ECEC) was calculated as the sum of the values of the last two measurements (sum of the exchangeable cations and the exchangeable Al). Analyses were performed immediately after sampling. 15 Hydrocarbon analysis Extraction (5 g of sample N and Nbs) was performed with dichloromethane:acetone (1:1) using a Soxtherm extraction apparatus (Gerhardt GmbH & Co. -

LTPs play a role in several biological processes, including the root nodule symbiosis. In this regard, the Medicago truncatula nodulin 5 (MtN5) LTP has been proved to positively regulate the nodulation capacity, controlling rhizobial infection and nodule primordia invasion. To better define the lipid transfer protein MtN5 function during the symbiosis, we produced MtN5-downregulated and -overexpressing plants, and we analysed the transcriptomic changes occurring in the roots at an early stage of Sinorhizobium meliloti infection. We also carried out the lipid profile analysis of wild type (WT) and MtN5-overexpressing roots after rhizobia infection. The downregulation of MtN5 increased the root hair curling, an early event of rhizobia infection, and concomitantly induced changes in the expression of defence-related genes. -

Niiranen , MD, PhD BACKGROUND: Several small-scale animal studies have suggested that gut microbiota and blood pressure (BP) are linked. However, results from human studies remain scarce and conflicting. We wanted to elucidate the multivariable-adjusted as- sociation between gut metagenome and BP in a large, representative, well-phenotyped population sample. We performed a focused analysis to examine the previously reported inverse associations between sodium intake and Lactobacillus abun- dance and between Lactobacillus abundance and BP. METHODS AND RESULTS: We studied a population sample of 6953 Finns aged 25 to 74 years (mean age, 49.2±12.9 years; 54.9% women). The participants underwent a health examination, which included BP measurement, stool collection, and 24-hour urine sampling (N=829). Gut microbiota was analyzed using shallow shotgun metagenome sequencing. In age- and sex-adjusted models, the α (within-sample) and β (between-sample) diversities of taxonomic composition were strongly re- lated to BP indexes (P<0.001 for most). In multivariable-adjusted models, β diversity was only associated with diastolic BP (P=0.032). -

After desalting and water dilution of the raw CEP, samples were exposed to exponentially decay waveform pulses for up to 463 µs at electric field intensities ranging from 19 to 38 kV cm−1. Pulses were applied in monopolar mode. Experimental data were fitted to a first-order kinetic model as well as to models based on Fermi, Hulsheger¨ or Weibull equations to describe PE inactivation kinetics. Characteristic parameters for each model were calculated. Relationships between some of the parameters and process variables were obtained. The Weibull model yielded the best accuracy factor. The relationship between residual PE and input of electrical energy density was found to be that of exponential decay. 2005 Society of Chemical Industry Keywords: pulsed electric fields; kinetics; pectinesterase; model; inactivation INTRODUCTION It has become customary to use CEPs in fruit and Pectinesterase (PE; EC 3.1.1.11) is a pectic enzyme vegetable juice technology.

They impose a barrier Tannin against phytopathogens invasion in plants and thus oppose diseases occurrence in them. Tannase is an enzyme Tannase known for its ability to degrade plant tannins. Important plant pathogens also possess tannase coding sequence in Plant defense their genome. Researches on tannase are till date focused on its applications in animal nutrition, in bioreme Pathogen diation and in food industries etc. The information about tannase role with respect to pathogen’s virulence is Virulence very scanty or almost nil in scientific literature. The presence of tannase in pathogen’s genome is an adaptive feature which may be a part of its strategy to overcome the negative effects of plants tannins. The present review summarizes important aspects of tannase and its possible role in disease causing ability of pathogens in plants. 1. Introduction hydrolyzable tannins (Zhang et al., 2001). In complex tannins, a cate chin or epicatechin unit is bound glycosidically to a gallotannin or an Tannins are universally present in plants and represent the fourth ellagitannin unit to yield catechin or epicatechin and gallic acid or most abundant group of secondary metabolites after cellulose, hemi ellagic acid upon hydrolysis. -
