Fig. 3: AlCl3 stress induces an increase in GABA content and GAD activity.

One-week-old hybrid Liriodendron seedlings of somatic embryos were subjected to 30 μM AlCl3 stress for the indicated amount of time, after which the GABA content (A) and GAD activity (B) were measured. The experiment was performed in triplicate. The data represent the mean ± SD of three biological replicates
