Figure 5. Expression levels of PDK1, OXI1 and AGC2-2 genes and defense genes in colonized wild-type or mutant roots relative to uncolonized control plants.

Panel A shows PDK1, OXI1 and AGC2-2 expression levels and panel B shows expression levels of several defense genes. RNA was extracted from roots and real-time PCR analyses were performed with the housekeeping gene UBQ5 as control. Calculations were performed according to [63]. Bars show the mean out of at least four independent experiments with SEs. Data are presented on a log scale.
