Analysis of PAO activity, free polyamines and ROS levels in wild type (WT) and transgenic plants (#25 and #27).
(a) PAO activities in the wild type (WT) and transgenic lines (#25 and #27). (b) Levels of free putrescine (Put), spermidine (Spd), spermine (Spm) and 1, 3-Diaminopropane (Dap) in WT and transgenic lines. (c) H2O2 and O2•− contents in WT and transgenic lines. Error bars represent standard deviations (n = 3). Asterisks indicate significant difference between transgenic lines and WT (*P < 0.05, **P < 0.01, ***P < 0.001).
