Used in plant biology research to quantify levels of allene oxide synthase (AOS), an enzyme involved in the biosynthesis of jasmonic acid, a key signaling molecule in plant defense and stress responses. The kit enables researchers to measure AOS activity in plant tissue samples, helping to study plant responses to herbivory, pathogen attack, wounding, and environmental stresses. It is widely applied in agricultural research, plant physiology, and genetic studies to evaluate the activation of the oxylipin pathway and to compare AOS expression across different plant species, mutants, or treatment conditions. The assay is typically used in laboratory settings for high-throughput screening and mechanistic studies of plant immune responses.
