Expression profiles of five miRNAs and their putative NB-LRR (PaLRR) targets in the bark of Norway spruce 1–6 days after inoculation with the necrotrophCeratocystis 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). For LRRs expression levels are given as fold change relative to intact control trees at each time point. For miRNAs expression is given as relative PCR cycle differences (ddCt). Dotted horizontal lines indicate equal expression in treatments and controls. n=2 trees.
