Fig. 7 From:通用电气nome-wide study of C2H2 zinc finger gene family inMedicago truncatula Confirmation of C2H2 ZFPs specifically expressed inM. truncatulasymbiotic nodules. The qRT-PCR result of six selected C2H2 genes. Shown are means ± standard deviations for three biological replicates and three technical replicates of each biological replicate. The relative expression levels of tested genes were normalized by the geometric mean of three endogenous control genes. ‘N.A.’ indicated undetectable expression. The lowercase letters above the bar indicate significant differences (P < 0.05) using ANOVA and Tukey’s test among samples Back to article page
