Effects of MT, CO, MT + CO, and MT + Hb on the levels of Uro III (a), Proto IX (b), Mg-Proto IX (c), Pchlide (d) and the expression of SlUROD(e), SlPPOX(f), and SlMGMT (g) in tomato seedlings under drought stress. The data are the average of three replicates and are presented as means ± SE. Different letters indicate significant differences at P < 0.05 according to Duncan’s multiple range tests
