Effects of biotic and abiotic stresses on miRNA relative expression evaluated by RT-qPCR. A) Comparative analyses of four libraries from the water deficit experiment. For the water deficit-stress assay, the four libraries were named as: DSRC (drought-sensitive seedlings root submitted to 0 minutes of stress); DSRT (drought-sensitive seedlings root submitted to 125 minutes and 150 minutes of stress); DTRC (drought-tolerant seedlings root submitted to 0 minutes of stress) and DTRT (drought-tolerant seedlings root submitted to 125 minutes and 150 minutes of stress). B) Comparative analyses of four libraries from the rust infection experiment. For the rust-stress assay, the four libraries were named as: RSLC (rust-susceptible seedlings leaves mock inoculation); RSLI (rust-susceptible seedlings leaves with rust-spore inoculation); RRLC (rust-resistant seedlings leaves with mock inoculation) and RRLT (rust-resistant seedlings leaves with rust-spore inoculation). Samples that significantly differs (P < 0.05) according to a Students t-test statistical analysis, were label as: "*" effective differences between cultivars in control conditions; "a" effective differences between control and stressed conditions for sensitive or susceptible plants; "b" effective differences between control and stressed conditions for tolerant or resistant plants and "1" when an effective difference was also observed between sensitive or susceptible and tolerant or resistant under stress conditions.
