qRT-PCR analysis of seven sugarcane ScJAZ family genes in 4-month-old ROC22 plantlets after treatment with 5 mM SA, 100 μM MeJA and 100 μM ABA. Data was normalized to the GAPDH expression level. All data points were the means ± SE (n = 3). Different lowercase letters indicate a significant difference, as determined by the Duncan’s new multiple range test (p-value <0.05). SA, salicylic acid; MeJA, methyl jasmonate; ABA, abscisic acid
