Table 4. The concentration of individual free amino acids [μmol per g fresh weight] in A. thaliana plants at 21 days post inoculation with Verticillium dahliae (+Vd).

Values presented as the mean ± SD (n = 2), each experiment consisting of 30 plants, split into five pools of six plants, and analysed as two technical replicates. Asterisks indicate statistically significant differences (p < 0.05) between non-inoculated and inoculated plants.
