Figure 5From: Altered gene expression and ecological divergence in sibling allopolyploids of Dactylorhiza (Orchidaceae)Environmental variables that exert a relevant selective pressure. Bar chart summarising the significant regressions obtained with SAM [58] (see also Table 3). The level of significance (Q) is adjusted from P-values to control for type 1 errors with the FDR method [69]; only relationships with Q < 0.05 are retained. Some markers are associated with several ecological variables (Table 3).Back to article page
