Transcript accumulation pattern of AUX1, cyclins, and polyamine synthesis genes in rhizobia-infected PvRbohA-RNAi roots at 7 dpi. (A) Transcript levels (normalized to uninoculated roots) of P. vulgaris AUX1, (B) CYCB1-1, CYCD1, and CYCD3 cyclin genes, and (C) ADC and ODC polyamine synthesis genes in control and PvRbohA-RNAi roots. Transcript accumulation was normalized to the expression of the EF1α and IDE reference genes. Values represent the averages of three biological replicates (n > 9). The statistical significance of differences between control and PvRbohA-RNAi samples was determined using an unpaired two-tailed Student’s t-test (P < 0.05; ∗∗P < 0.01). Error bars represent means ± SEM. dpi, days post-inoculation; ADC, arginine decarboxylase; ODC, ornithine decarboxylase.
