Effects of a trans-2-hexenal treatment on plant metabolome alterations - a case study with tomato fruit
Green leaf volatiles (GLVs) are ubiquitous odors in the plant kingdom and modulate not only primary, but also secondary metabolism such as pyrethrin biosynthesis. One of the main tomato fruit GLVs, trans-2-hexenal, was applied to tomato fruit ('Micro-Tom') using a vapor treatment, and its ethylene-inducing ability and effects on primary metabolite alterations were investigated. The results obtained showed that trans-2-hexenal enhanced fruit ethylene production at 10 ppm and increased the concentrations of glucose, 4-aminobutyric acid (GABA), citric acid, and malic acid.
