SNPs/indels analysis in PPO genes of four agronomically important globe artichoke varietal types. (a) The total number of polymorphisms and a Venn diagram indicating intersections among the four varietal types are reported. (b) The number of variants per PPO, divided in exon and intron regions, is reported. (c) The number of the different types of variants (substitutions, insertions and deletions) is indicated. Abbreviations indicate Violetto di Toscana (VT), Violetto di Sicilia (VS), Romanesco C3 (C3) and Spinoso di Palermo (SP).
