Book Synopsis Characterization of the RpoN Global Regulatory Gene of Pseudomonas Syringae Pv. Syringae B728a and Its Impact on the Plant-pathogen Interaction by : Amber Lorge

Syringae B728a and Its Impact on the Plant-pathogen Interaction written by Amber Lorge and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Gene regulation in bacteria is highly complex and requires the activity of sigma factors that function as transcriptional regulators. In Pseudomonas syringae pv. syringae B728a, 14 sigma factors have been identified. One of the more interesting is rpoN, encoding Sigma 54, which was initially described for its role in nitrogen utilization and later shown to be involved in regulating adhesion, motility, toxin production, and pathogenicity. The only commonality identified amongst these genes is that gene regulation by Sigma 54 is not essential for normal growth and development because mutational inactivation of rpoN is not lethal. Unlike Sigma 70, which recognizes promoter sites located at positions -10/-35 upstream of the transcription initiation site, Sigma 54 recognizes sites located at positions -12/-24. P.s. pv. syringae B728a encodes an RpoN that shares 80-98% identity with other Pseudomonas species. Promoter scans were conducted on the B728a genome to look for probable binding sites of RpoN. Analysis revealed that RpoN may be involved in regulating genes encoding ABC transporters, drug efflux pumps, flagella proteins, nitrate transporters, and several regulatory proteins. An insertional mutation in the rpoN gene was constructed in the B728a genome and a phenotypic analysis was initiated. Decreased swarming and adhesion ability of the rpoN mutant was observed as compared to B728a. The ability to utilize sole nitrogen sources was also affected. The rpoN mutant showed little or no growth on sole nitrogen sources such as alanine, histidine, lysine, and serine. Pathogenicity was shown to require a functional RpoN, as both HR and disease development was effected by an rpoN mutation. Pseudomonas syringae pv. syringae is most known for the production of two phytotoxins. Unlike RpoN in other species, in P.s. pv. syringae B728a it appears to indirectly down regulate toxin production of syringomycin and syringopeptin. The goal of this study was to characterize some of the important roles RpoN is known to possess and to understand its role in the plant pathogenic and epiphytic lifestyle of P. s. pv. syringae B728a.
Book Synopsis Virulence and Gene Regulation by : Juan-Luis Ramos
Download or read book Virulence and Gene Regulation written by Juan-Luis Ramos and published by Springer Science & Business Media. This book was released on 2004-06-17 with total page 584 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pseudomonas comprises three volumes covering the biology of pseudomonads in a wide context, including the niches they inhabit, the taxonomic relations among members of this group, the molecular biology of gene expression in different niches and under different environmental conditions, the analysis of virulence traits in plants, animals and human pathogens as well as the determinants that make some strains useful for biotechnological applications and promotion of plant growth. There has been growing interest in pseudomonads and a particular urge to understand the biology underlying the complex metabolism of these ubiquitous microbes. These bacteria are capable of colonizing a wide range of niches, including the soil, the plant rhizosphere and phylosphere, and animal tissues; more recently they have attracted attention because of their capacity to form biofilms, a characteristic with potentially important medical and environmental implications. The three volumes cover the following topics: - Taxonomy, - Genomics, - Life styles, - Cell Architecture, - Virulence, - Regulation, - Macromolecules, - Alternative Respiratory Substrates, - Catabolism and Biotransformations. Pseudomonas will be of use to all researchers working on these bacteria, particularly those studying microbiology, plant crops, pathogenesis, and chemical engineering. Advanced students in biology, medicine and agronomy will also find these three volumes a valuable reference during their studies.

Download or read book Comprehensive and Molecular Phytopathology written by Yuri Dyakov and published by Elsevier. This book was released on 2007-01-09 with total page 497 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a collection of information on successive steps of molecular 'dialogue' between plants and pathogens. It additionally presents data that reflects intrinsic logic of plant-parasite interactions. New findings discussed include: host and non-host resistance, specific and nonspecific elicitors, elicitors and suppressors, and plant and animal immunity. This book enables the reader to understand how to promote or prevent disease development, and allows them to systematize their own ideas of plant-pathogen interactions.* Offers a more extensive scope of the problem as compared to other books in the market* Presents data to allow consideration of host-parasite relationships in dynamics and reveals interrelations between pathogenicity and resistance factors* Discusses beneficial plant-microbe interactions and practical aspects of molecular investigations of plant-parasite relationships* Compares historical study of common and specific features of plant immunity with animal immunity
