Defense responses of Fusarium oxysporum to 2,4-diacetylphloroglucinol, a broad-spectrum antibiotic produced by Pseudomonas fluorescens.
A collection of 76 plant-pathogenic and 41 saprophytic Fusarium oxysporum strains was screened for sensitivity to 2,4-diacetylphloroglucinol (2,4-DAPG), a broad-spectrum antibiotic produced by multiple strains of antagonistic Pseudomonas fluorescens. Approximately 17% of the F. oxysporum strains were relatively tolerant to high 2,4-DAPG concentrations. Tolerance to 2,4-DAPG did not correlate wi...
متن کاملAntibiotic Produced by Pseudomonas fluorescens
Rapid increase of resistance to antibacterial agents in recent years has become a major global public health problem.1,2) The development of antibiotics with novel mechanisms of action is one of the most important measures leading to the control of bacterial infectious diseases in the new millennium. The genomic antibacterial approach plays a critical role in the discovery of new targets by sea...
متن کاملControl of Fusarium Oxysporum Causing Fusarium Wilt by Trichoderma Spp and Pseudomonas fluorescens on Arachis hypogaea L
Fusarium wilt diseases caused by the fungus Fusarium oxysporum lead to significant yield losses of crops. Biocontrol agents such asTrichoderma viride , Trichoderma harzianum and Pseudomonas fluorescens are applied to control Fusarium wilt of Arachis hypogaea. Experiments were conducted on the effect of culture filtrates of T.viride (1%), T.harzianum (1.5%), and P. fluorescens (2%) on biochemica...
متن کاملAntifungal Activity of (KW)n or (RW)n Peptide against Fusarium solani and Fusarium oxysporum
The presence of lysine (Lys) or arginine (Arg) and tryptophan (Trp) are important for the antimicrobial effects of cationic peptides. Therefore, we designed and synthesized a series of antimicrobial peptides with various numbers of Lys (or Arg) and Trp repeats [(KW and RW)(n)-NH(2), where n equals 2, 3, 4, or 5]. Antifungal activities of these peptides increased with chain length. Light microsc...
