Transcript abundance regulation as observed by RNASeq. a Principal component analysis separating the data sets of non-triggered (C, P), cold-triggered (T-C and PT-C) and light-triggered samples (T-L and PT-L) stronger according to the type of the triggering stimulus than to the priming effect (P or PT in comparison to C or T). b Cluster analysis of transcript abundance regulation in cold- or light-triggered, primed or unprimed samples relative to the transcript level in control plants. The heat map lists only genes that were at least 2-fold stronger or less expressed in primed and / or triggered plants than in C-plants (FDR value < 0.001). 10-fold up-regulated transcripts are shown in dark red, 10-fold down-regulated transcripts are shown in blue. c VENN-diagrams depicting the number of genes up- or down-regulated in a priming-dependent manner before (P) and after cold (PT-C) or light triggering (PT-L) at a strong threshold setting of log₂ (primed/unprimed) ≥ I 1 I and FPKM ≥10 (top) or a weak threshold setting of log₂ (primed/unprimed) ≥ I 0.5 I and FPKM ≥5 (bottom)
