Altered expression of a set of regulatory genes in response to MJ treatment. Treatment with 100 μM MJ altered the mRNA levels of a set of regulatory genes that may be involved in wound signal transduction. Each value is the mean ± SE of 3 independent biological determinations, and the data shown are relative ratios. The genes were named according to their functional annotation. CK: healthy calli controls; MJ: calli treated with MJ for 5 days.
