(A) Distribution of SNPs along the E. lucius 5S rDNA unit. Data were obtained from mutation analysis of Illumina reads (Additional file 4: Table S1). Note, absence of SNPs in the internal controlling region composed of Box-A, IE and Box-C elements. MNP–multinucleotide polymorphism defining two prominent spacer variants (“T” and “A”). (B) Distribution of IGS variants in three PacBio reads (a - c). Slanted lines indicate tandemly arranged units visualized through the alignment of reads (x-axis) with a 5S gene (y-axis). The position of the “T” and “A”. variants is indicated
