From: Genome-wide identification and analysis of WRKY gene family in maize provide insights into regulatory network in response to abiotic stresses

Fig. 7

Expression profiles of 21 ZmWRKY genes under drought stress treatments in two different tissues. QRT-PCR data was normalized using maize Actin gene. X-axes represent various treatments (CK, normal condition; D1, D2, D4 and D8 indicate hours of drought treatment in leaves. D2 and D4 indicate hours of drought treatment in roots.). And different genes and y-axes are scales of relative expression level. Error bars result from three biological replicates. Asterisks on top of the error bars represent the significance levels. *Significantly different at P < 0.05; ** significantly different at P < 0.01
