The Arabidopsis Ubiquitin gene was used as an internal reference. Experiments were independently repeated three times. Data was normalized to +Zn/-AzA condition, log2 transformed and visualized using "clustered correlation" CIM (http://discover.nci.nih.gov) [64]. Stars indicate genes involved in the biosynthesis and response to salicylic acid.
