Fig. 2From: Exome resequencing and GWAS for growth, ecophysiology, and chemical and metabolomic composition of wood of Populus trichocarpaNumber of significant single-SNPs (left) and sliding windows (right) associated with a selected set of traits for growth (a), stable isotopes parameters (c), chemical components of wood (b) and selected metabolites (c). Blue line at the left graphs indicates the proportion (‰) of significant SNP calculated on the total of analyzed SNP per chromosome. Significance thresholds considered a p-value < 6.1479E-8 for single-SNPs (a and c), and 1.04E-03 and 5.05E-04 for C6-sugars (b) and GAc (d) sliding windows, respectively.
