Fig 10. Quantitative real-time RT-PCR of selected genes related to plant growth (growth modulators) and innate immunity (recognition and transduction of signals, pathogenesis-related proteins, secondary metabolisms, oxidant stress and fluxes, phytohormone balances).

Transcript abundances were recorded in leaf and root tissues of wheat (cv. Karim) at 28 days after seed inoculation with PGPR (10⁸ CFU / mL). Transcript abundances of the genes were recorded by real-time qRT-PCR analyses in the PGPR-infected plants and were relative to those of the control using the 2^−ΔΔCT method. The significant differences were statistically analyzed based on three independent biological replications. Each biological repetition corresponds to a mix of five plants (Tukey’s test, adjusted p < 0.05). Complete statistical data, including the SE, are detailed in S2 Table. Colors represent level of transcriptional expressions (blue: up-expression; red: down-expression).
