Expression profile of AtPNP-A and correlated genes in response to selected treatments. The results presented illustrate the fold change (log2) in expression of AtPNP-A, WRKY 70 and WRKY 46 and the average fold change for the 25 correlated genes in response to abiotic stresses (A) and biotic and chemical treatments (B). (A) The treatments were: UV-B shoot 3 h (n = 2); O3 6 h (n = 3); Osmotic stress in the shoot after 3 h (n = 2); K+ starvation in the shoot after 7 days (n = 3); NaCl in the roots after 6 h (n = 2) and cold acclimation after 14 days (n = 3). (B) The treatments were: Erysiphe cichoracearum 3 days after inoculation (n = 4); Erysiphe orontii 3 days after inoculation (n = 2); Phytophthora infestans 1 day after inoculation (n = 3); BTH after 8 h (n = 3); SA after 3 h (n = 2) and cyclohexamide after 3 h (n = 2). Error bars represent standard errors of the mean.
