Genes expression profile of genes involved in GABA metabolism (GAD1, GABAT, PAO2, PAO4) analysed by real-time PCR. Bars represent averages ± SD of 3 biological replicates of mycorrhizal (Myc) and non-inoculated (Cont) cork oak plants. *Indicate statistical differences at the level P < 0.05 (Mann–Whitney U test).
