Marcatori molecolari per la tracciabilità del cardoncello

In this work the authors analyzed sixty italian strains of the edible mushroom "cardoncello" (Pleurotus eryngii) belonging to the varieties eryngii and ferulae by sequencing two housekeeping genes (ef1-a and rpb2) and evaluating the activity of peroxidase, superoxide dismutase and catalase, in order to find some molecular markers for the traceability of "cardoncello". Sequence analysis showed the presence of Snps variety-specific (eryngii and ferulae) in both genes useful for the development of molecular identification tools. none correlation between enzymatic analysis and analyzed varieties was observed.
