Abscisic acid metabolism-related gene expression in roots of Moneymaker tomato plants non-colonized (NI) or colonized with R. irregularis (I). Gene expression was measured by qPCR 50 days after inoculation. qPCR data represent the expression of target genes as M-value with respect the expression of CYP707A1 in non-colonized plants (the biological replicate with lower expression) in which the expression was designated to be M = 0 and all other samples were expressed relative to it. Values correspond to mean ± SE (n = 3). For each gene, bars with same letters are not significantly different (P = 0.05) according to Duncan’s multiple range test.
