Figure 1

Overlap in differential expression patterns from both transcript and protein profiling. Numbers of differentially expressed genes in P. cheesemanii (CH), P. exile (EX) and P. novae-zelandiae (NZ) identified by transcript (T) profiling, protein profiling (P) or both (TP). Differential expression is defined as significantly higher or lower expression in one species compared with the other two combined (panel A - 6 group comparisons) or separately (panel B - 6 pair wise comparisons) and was determined by linear model analysis (transcripts) or Wilcoxon rank and t-tests (proteins). Numbers are corrected for relative sizes of transcript and protein data sets. In other words, only a subset of all differentially expressed transcripts and proteins is given. This subset consists of genes found amongst the 1074 loci surveyed by both transcript and protein profiling. For a summary of all differentially expressed transcripts and proteins refer to table 2. Upper percentages depict the proportion of transcripts confirmed by protein analysis and lower percentages depict the proportion of proteins confirmed by transcript analysis (see text for details). Statistically significant overlap (p value < 0.05%) is denoted with a star. For locus IDs, gene descriptions, transcript and protein expression statistics of genes identified as being up-regulated by both methods (TP) in CH, EX and NZ see table 3.
