Fig. 2From: Impact of novel SNPs identified in Cynara cardunculus genes on functionality of proteins regulating phenylpropanoid pathway and their association with biological activitiesDistribution of the observed haplotypes in C3′H (a) and HQT (b) genes. The size of the circles is proportional to haplotype frequency, the length of the lines is proportional to the number of mutation steps between genotypes and their proximal states, and pie charts indicate the contribution of plant origin groups to a particular haplotypeBack to article page
