    • Characterization of CorR, a transcriptional activator which is required for biosynthesis of the phytotoxin coronatine 

      Penaloza-Vazquez, Alejandro; Bender, Carol L. (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 the alginate biosynthetic gene cluster in Pseudomonas syringae pv. syringae 

      Penaloza-Vazquez, Alejandro; Kidambi, Saranga P.; Chakrabarty, Ananda M.; Bender, Carol L. (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 ...

    • Novel virulence gene of Pseudomonas syringae pv. tomato strain DC3000 

      Preiter, Karen; Brooks, David M.; Penaloza-Vazquez, Alejandro; Sreedharan, Aswathy; Bender, Carol L.; Kunkel, Barbara N. (American Society for Microbiology, 2005-11)
      Previously, we conducted a mutant screen of Pseudomonas syringae pv. tomato strain DC3000 to identify genes that contribute to virulence on Arabidopsis thaliana plants. Here we describe the characterization of one mutant ...

    • Optimization of Coronatine Production in a Genetically Improved Strain of Pseudomonas Syringae 

      Bender, Carol L.; Penaloza-Vazquez, Alejandro; Board of Regents/Oklahoma State University and the A & M Colleges (U.S. Patent and Trademark Office, 2009-08-25)
      Stable genetically engineered bacterial strains that overproduce coronatine are provided. The stable strains can be successfully cultivated to overproduce coronatine at temperatures that are suitable for large scale, ...

    • Regulation of alginate biosynthesis in Pseudomonas syringae pv. Syringae 

      Fakhr, Mohamed K.; Penaloza-Vazquez, Alejandro; Chakrabarty, Ananda M.; Bender, Carol L. (American Society for Microbiology, 1999-06)
      Both Pseudomonas aeruginosa and the phytopathogen P. syringae produce the exopolysaccharide alginate. However, the environmental signals that trigger alginate gene expression in P. syringae are different from those in P. ...
