Phylogenomic investigation of safflower (Carthamus tinctorius) and related species using genotyping-by-sequencing (GBS).

ABSTRACT: Safflower (Carthamus tinctorius, Asteraceae) is a source of high-quality edible oil growing in moisture-limited environments. Despite its economic importance, the relationships to close wild species in Carthamus and the presence and relationships of ecotypes within safflower are still not fully clarified. Here we use genotyping-by-sequencing to identify the wild progenitor of C. tinctorius, infer phylogenetic relationship within the series Carthamus and identify groups of closely related lineages within cultivated safflower. Phylogenetic and population genomic analyses found C. palaestinus to be the closest relative and single progenitor of C. tinctorius, which confirms the Levant as the area of domestication of the crop. Flow cytometry showed all analyzed samples of C. oxyacantha, C. pala
