The biosynthesis of brassicicolin A in the phytopathogen Alternaria brassicicola.

Alternaria brassicicola (Schwein.) Wiltshire is a phytopathogenic fungus that together with A. brassicae causes Alternaria black spot disease in Brassica species.

Metabolite diversity in the plant pathogen Alternaria brassicicola: factors affecting production of brassicicolin A, depudecin, phomapyrone A and other metabolites.

A systematic investigation of the metabolites of Alternaria brassicicola produced under various culture conditions is reported. The phytotoxin brassicicolin A is produced in significantly larger amounts in potato dextrose broth than in minimal medium cultures. In general an increase in the incubation temperature of cultures 23-30 C increases the production of brassicicolin A but decreases depudecin production.

Identification of an ISR-related metabolite produced by rhizobacterium Klebsiella oxytoca C1036 active against soft-rot disease pathogen in tobacco.

Background: Klebsiella oxytoca C1036 (C1036) causes induced systemic resistance (ISR) activity against the soft-rot pathogen Pectobacterium carotovorum subsp. carotovorum SCC1 (SCC1). However, microbial metabolites from C1036 involved in ISR activity remain unknown.

Identification of an ISR-related metabolite produced by Pseudomonas chlororaphis O6 against the wildfire pathogen pseudomonas syringae pv.tabaci in tobacco.

Pseudomonas chlororaphis O6 exhibits induced systemic resistance (ISR) against P. syringae pv. tabaci in tobacco.
