Circos plot integrating the genomic positions of ZYMV-related markers, pathogen recognition genes and small variants (SNP, Single Nucleotide Polymorphisms and InDel: insertion/deletion). Inset legend provides information for the data rings. Track A denotes the 20 pseudochromosomes (LG, linkage group) of Cucurbita pepo. The length of each circle segment represents the size of pseudochromosomes expressed in megabases (Mb). An orange arrow indicated the marker associated with ZYMV tolerance identified by Capuozzo et al. [11]. Track B shows, as a scatterplot, the genomic position of nucleotide-binding domain leucine-rich repeat containing receptors (NLR; blue spots) and receptor-like proteins and receptor-like kinase (PPR; green spots), annotated by Andolfo et al. [19]. Tracks C and D show the variants density, represented as heat maps (number/Mb) in C. pepo 381e and C. pepo TF cultivars, respectively
