Fig. 1. Comparison of total ion and selected ion chromatograms of extracts from CuCl2-treated and control barley leaves. The barley leaves were treated with 0.5 mM CuCl2 solution by the floating method. Metabolites in the leaves were extracted 72 h after treatment and analyzed by LC-MS. Three independent samples (3 plant/sample) from either CuCl2 treated or control leaves were analyzed, and increased accumulation of 1–3 in the CuCl2 treated leaves was detected in all analyses.
