Dependence of gene regulation by prostaglandin A1 on a zinc finger protein

A zinc finger protein (At3g62900) was identified as a putative signalling factor mediating gene regulation to reactive electrophilic oxylipin. We used microarrays to investigate the effect of a defect in the zinc finger on gene expression. Arabidopsis seedlings of Col-0 and mutants were treated with prostaglandin A1 or mock for 4 h.
