‘Asti Sorì’ (or ‘Carciofo Astigiano del Sorì’) is a globe artichoke local ecotype cultivated in the hills of Asti (Italy), recognized as a presidium by the “Slow Food Foundation for Biodiversity”. With the aim to enhance its preservation as well as to accelerate the valorization and breeding of this ecotype, we performed an Illumina resequencing of two ‘Asti Sorì’ genotypes achieving coverage up to 35×. We reconstructed their genome sequences at a chromosomal scale, conducted structural and functional annotations, and compared them to previously available sequences from genotypes representing the globe artichoke core varietal types and a genotype of the related taxa cultivated cardoon. This work contributes to increasing the existing globe artichoke genomic resources and paves the way for the safeguarding of this Piedmont landrace.

Abstract
‘Asti Sorì’ (or ‘Carciofo Astigiano del Sorì’) is a globe artichoke local ecotype cultivated in the hills of Asti (Italy), recognized as a presidium by the “Slow Food Foundation for Biodiversity”. With the aim to enhance its preservation as well as to accelerate the valorization and breeding of this ecotype, we performed an Illumina resequencing of two ‘Asti Sorì’ genotypes achieving coverage up to 35×. We reconstructed their genome sequences at a chromosomal scale, conducted structural and functional annotations, and compared them to previously available sequences from genotypes representing the globe artichoke core varietal types and a genotype of the related taxa cultivated cardoon. This work contributes to increasing the existing globe artichoke genomic resources and paves the way for the safeguarding of this Piedmont landrace.
