From: Lack of ITS sequence homogenization in Erysimum species (Brassicaceae) with different ploidy levels

Figure 1

Boxplot depicting the nucleotide diversity (π) for ITS1 and ITS2 samples. Nucleotide polymorphism was estimated for each Erysimum individual as the average number of nucleotide differences per site between two sequences (Nei and Li47). E. baeticum (Ebb, ploidy 8x), E. bastetanum (Ebt, ploidy 4x and 8x), E. popovii (Ep, ploidy 4x and 10x), and one population of E. mediohispanicum (Em, ploidy 4x) are polyploids. E. nevadense (En), E. fitzii (Ef), two populations of E. mediohispanicum (Em), and E. lagascae (Ela) are diploids.
