Metabolism of volatile metabolites in soybean varieties infected by Fusarium oxysporum

This is the first report of screening for volatile metabolite metabolism in local soybean cultivars affected by Fusarium blight. Volatile metabolites in the aerial and root parts of three local soybean varieties (Glycine max (L.) Merr.) infected with the Fusarium oxysporum fungus were monitored using gas chromatography. The results showed no significant differences in the volatile metabolites between the above-ground and root parts of the plants. However, as the disease progressed, an increase in the number of similar metabolites was observed in the root parts. Conversely, the quantity of similar volatile metabolites in the aerial parts of the plants decreased as the disease advanced. Notably, 4-aminobenzoic acid was detected in all parts of the samples, with higher concentrations found in the aerial parts than in the root parts.
