  1. The quantities of metabolites were analyzed using GC-MS, and their levels were normalized to ribitol and calculated as ug per g fresh weight of leaves. The data presented represent mean ± SE of six biological repetitions of leaves collected from eight plants per line. aND represents the metabolite was not detected due to low concentration. bUp represents the metabolite is up-regulated in 4× as compared to 2× (Student’s t-test).
