Central Limit Theorem for the number of real roots of random orthogonal polynomials
(2021-11-17)In this note we study the number of real roots of a wide class of random orthogonal polynomials with gaussian coefficients. Using the method of Wiener Chaos we show that the fluctuation in the bulk is asymptotically gaussian, ... -
Characterization and identification of productivity-associated rhizobacteria in wheat
(American Society for Microbiology, 2012-06)The rhizosphere is populated by a numerous and diverse array of rhizobacteria, and many impact productivity in largely unknown ways. Here we characterize the rhizobacterial community in a wheat variety categorized according ... -
Characterization and transcriptional analysis of the gene cluster for coronafacic acid, the polyketide component of the phytotoxin coronatine
(American Society for Microbiology, 1995-11)Coronafacic acid (CFA), the polyketide component of the phytotoxin coronatine (COR), is activated and coupled to coronamic acid via amide bond formation, a biosynthetic step presumably catalyzed by the CFA ligase (cfl) ... -
Characterization of alginate lyase from Pseudomonas syringae pv. Syringae
(American Society for Microbiology, 2000-11)The gene encoding alginate lyase (algL) in Pseudomonas syringae pv. syringae was cloned, sequenced, and overexpressed in Escherichia coli. Alginate lyase activity was optimal when the pH was 7.0 and when assays were conducted ... -
Characterization of Anaplasma marginale isolated from North American bison
(American Society for Microbiology, 2003-08)Anaplasma marginale (Rickettsiales: Anaplasmataceae), a tick-borne pathogen of cattle, is endemic in tropical and subtropical regions of the world. Although serologic tests have identified American bison, Bison bison, as ... -
Characterization of Cfa1, a monofunctional acyl carrier protein involved in the biosynthesis of the phytotoxin coronatine
(American Society for Microbiology, 2004-04)Cfa1 was overproduced in Escherichia coli and Pseudomonas syringae, and the degree of 4'-phosphopantetheinylation was determined. The malonyl-coenzyme A:acyl carrier protein transacylase (FabD) of P. syringae was overproduced ... -
Characterization of CorR, a transcriptional activator which is required for biosynthesis of the phytotoxin coronatine
(American Society for Microbiology, 1998-12)Coronatine (COR) is a plasmid-encoded phytotoxin synthesized by several pathovars of phytopathogenic Pseudomonas syringae. The COR biosynthetic gene cluster in P. syringae pv. glycinea PG4180 is encoded by a 32-kb region ... -
Characterization of immunodominant and potentially protective epitopes of Mannheimia haemolytica serotype 1 outer membrane lipoprotein PlpE
(American Society for Microbiology, 2004-12)Mannheimia haemolytica serotype 1 (S1) is the most common bacterial isolate found in shipping fever pneumonia in beef cattle. Currently used vaccines against M. haemolytica do not provide complete protection against the ... -
Characterization of Pseudomonas aeruginosa mutants deficient in the establishment of lysogeny
(American Society for Microbiology, 1978-06)Mutants of Pseudomonas aeruginosa with impaired ability to establish a lysogenic relationship with temperate bacteriophage (Les-) have been isolated. These les mutations map to two areas of the P. aeruginosa chromosomal ... -
Characterization of recombinant B. abortus strain RB51SOD toward understanding the uncorrelated innate and adaptive immune responses induced by RB51SOD compared to its parent vaccine strain RB51
(Frontiers Media, 2011-11-25)Brucella abortus is a Gram-negative, facultative intracellular pathogen for several mammals, including humans. Live attenuated B. abortus strain RB51 is currently the official vaccine used against bovine brucellosis in the ... -
Characterization of the alginate biosynthetic gene cluster in Pseudomonas syringae pv. syringae
(American Society for Microbiology, 1997-07)Alginate, a copolymer of D-mannuronic acid and L-guluronic acid, is produced by a variety of pseudomonads, including Pseudomonas syringae. Alginate biosynthesis has been most extensively studied in P. aeruginosa, and a ... -
Characterization of the oxidative stress stimulon and PerR regulon of Campylobacter jejuni
(BioMed Central, 2009-10-18)Background: During gut colonization, the enteric pathogen Campylobacter jejuni must surmount the toxic effects of reactive oxygen species produced by its own metabolism, the host immune system, and intestinal microflora. ... -
Characterization of the Pseudomonas aeruginosa recA analog and its protein product: rec-102 is a mutant allele of the P. aeruginosa PAO recA gene
(American Society for Microbiology, 1987-04)We cloned a 2.3-kilobase-pair fragment of the Pseudomonas aeruginosa PAO chromosome which is capable of complementing recA mutations of Escherichia coli. The recA-complementing activity was further localized to a ... -
Characterization of the Pseudomonas aeruginosa recA gene: The Les- phenotype
(American Society for Microbiology, 1988-02)The Les- phenotype (lysogeny establishment deficient) is a pleiotropic effect of the lesB908 mutation of Pseudomonas aeruginosa PAO. lesB908-containing strains are also (i) deficient in general recombination, (ii) sensitive ... -
Characterization of the small RNA component of leaves and fruits from four different cucurbit species
(BioMed Central, 2012-07-23)Background: MicroRNAs (miRNAs) are a class of non-coding small RNAs involved in post-transcriptional regulation of gene expression critical for plant growth and development, stress responses and other diverse biological ... -
