a SNP distribution and abundance in Aglianico (left) and Falanghina (right) genomes relative to the Pinot Noir reference genome (PN40024_12X.v2). From the inner circle the plots show: chromosome size; GC content in 100 Kbp bins; gene content in 100 Kbp bins; SNPs/INDELs in 100 Kbp bins; GAIN in 100 Kbp bins; LOSS in 100 Kbp bins; Duplications in 100 Kbp bins. b Gene Ontology Enrichment Analysis (GOEA) results performed on AGL (left) and FAL (right) genes harboring missense mutations and genes including polymorphisms altering CDS length. Enriched terms related to biological process are reported. c Summary of high-impact variants found in AGL and FAL within enzyme-coding genes involved in the terpenoids (TPS, terpene synthase), GLVs (MCC, Methylcrotonyl-CoA carboxylase), BCAA (AAT, alcohol acetyltransferase) and phenylpropanoid (PAL, phenylalanine ammonia-lyase; 4CL, 4-coumarate: CoA ligase; CHS, chalcone synthase) biosynthetic pathways. * stands for stop codon
