Fig. 5From: Exome resequencing and GWAS for growth, ecophysiology, and chemical and metabolomic composition of wood of Populus trichocarpaVenn diagrams for the comparison between the present study (blue circles) and the one carried out by Wegrzyn et al .[18] (green circles). Forty genes encoding enzymes involved in lignin and cellulose biosynthesis and cytoskeletal proteins were compared. Numbers in circles indicate the number of genes containing significant SNPs (p < 0.0001). A detailed list is given in Additional file 2: Table S5Back to article page
