Abstract
  • A set of 24 microsatellite markers was identified in the artichoke genome, using various approaches. A genomic library allowed the development of 14 SSR markers, whereas the other 10 were obtained from gene intron/UTR regions or from other species. Allelic variation was scored in C. cardunculus (artichoke, cultivated cardoon, and wild cardoon) samples, and in other wild Cynara allies. For the 23 polymorphic loci, a total of 165 alleles were scored, 135 of which in the artichoke primary genepool, and the remaining ones in the other Cynara species. Some allele combinations were able to identify artichoke varietal types, and some alleles were unique to specific groups. This makes these markers potentially useful in product traceability and in contributing to the saturation of genetic maps. The percentage of shared alleles between C. cardunculus taxonomic groups, and Nei’s genetic distances indicated that wild cardoons from the Eastern Mediterranean were more closely related to artichoke and less to cultivated cardoon in comparison to wild cardoons from the Western Mediterranean, and the genetic distance between the two wild cardoon genepools was rather high. The UPGMA dendrogram based on Nei’s genetic distances revealed that artichokes formed a fairly defined cluster, whereas Eastern wild cardoons occupied another branch, and Western wild cardoons were clustered together with cultivated cardoons. The transferability of microsatellite markers to other Cynara wild species was quite good. Sequencing alleles at three loci showed that, apart from microsatellite length variation, point mutations and insertion/deletions were quite abundant especially when comparing C. cardunculus to the other Cynara species. In the sequenced regions, some SNPs were identified which distinguished artichoke on one side, and cultivated and wild cardoon on the other, while other SNPs were apportioned according to the geographic distribution of Cynara wild species.
