Abstract

Italy is leader in the production of chicory (Cichorium spp.) foods. Typical vegetables such as endive and escarole (C. endivia var. latifolium and var. chrispum) and "puntarelle" (C. intybus subsp. foliosum) are mainly consumed as fresh or minimally processed food. The project CISIA (Integrated Knowledge for the Agro-food Sustainability and Innovation for the made in Italy produce) is sustained by governmental and SMEs and aims at assessing the identity and traceability of local varieties (Lazio and Puglia shires) and at enhancing their nutritive and economic value by "olistic" approaches targeted to specific metabolites and gene pathways. The profiles of quality metabolite, related gene transcription and allelic variability will be used to fingerprint and valorise escarole, endive and "puntarelle" cultivars. In this context, the brassinosteroid (BR) pathway was widely investigated, considering that anti-cancer/anti-cholesterol properties of BR can impact on food quality and cultivar selection/marketing. The BR content of edible products (leaves) was quantified by Mass spectrometry in a set of patented and local cultivars and used to rank for BR accumulation. The BR biosynthetic and catabolic genes of C. intybus and C. endivia were identified by de novo transcriptome assembly of sequences obtained by Next Generation Sequencing. The comparison of BR gene expression pattern among the different cultivars will be combined with BR metabolic profile changes. Finally, variations of structural gene (SNP) and metabolite contents will be tested as markers for discrimination and traceability.
