Evaluation of differential auxin pathway regulation between BNF-contrasting genotypes. (a) Schematic representation of auxin pathway showing the DET identified related to auxin biosynthesis, auxin transporter and auxin signaling in roots and shoots of germinated stalks. In red are represented the transcripts more expressed in SP and in blue are represented the ones more expressed in CH. (b) Evaluation of crown roots in the stalk plants (naturally colonized by endophytes). (c) Representative photos of germinated stalks 15 days after planting of CH (left) and SP (right) demonstrate the differences observed in the quantitative analysis. Bars represent mean ± standard deviation of three biological replicates. Asterisks (*) represent significant difference between SP and CH at the same time point through t-test (p < 0.05).
