Expression profiles of three induced defence marker genes in the bark of Norway spruce 1–6 days after inoculation with the necrotroph Ceratocystis polonica (white dots) or wounding (black dots). Data points surrounded by a square are significant different from the control [p&0.05]. Trees were sampled at the treatment site (Position1) and 2–3 cm above the treatment site (Position 2). Gene expression is given as fold change relative to intact control trees at each time point. Dotted horizontal lines indicate equal expression in treatments and controls. n=2 trees.
