A rapid and simple method is described for the determination of indole-3-pyruvic acid (IPA) levels in Arabidopsis thaliana by gas chromatography-selected ion monitoring-mass spectrometry (GC-SIM-MS). The method includes derivatization of IPA with hydroxylamine in the crude extract, followed by ethyl

We evaluated the ability of metabolic elicitors extracted from Pseudomonas fluorescens N21.4 to induce systemic resistance (ISR) in Arabidopsis thaliana against the pathogen Pseudomonas syringae DC3000. Metabolic elicitors were obtained from bacteria-free culture medium with

Broadleaf weeds are very costly for crop growers. Additional herbicidal compounds need to be obtained, especially from natural sources. Extracts of Icacina trichantha were evaluated for responses in germinating seeds and seedlings of rice (Oryza sativa) and Arabidopsis (Arabidopsis thaliana). An

Rhizosphere-associated Streptomyces sp. AcH 505 (AcH 505) promotes infection of Norway spruce (Picea abies) with the pathogenic fungus Heterobasidion abietinum 331, while Streptomyces sp. GB 4-2 (GB 4-2) enhances spruce defense against the fungus. To identify whether these bacteria influence the

Pathogen-induced stomatal closure is part of the plant innate immune response. Phytopathogens using stomata as a way of entry into the leaf must avoid the stomatal response of the host. In this article, we describe a factor secreted by the bacterial phytopathogen Xanthomonas campestris pv campestris
