Abstract

Onopordum tauricum Willd., a species distributed in Eastern Europe, has been the subject ofvarious research endeavors aimed at assessing its suitability for extracting vegetable rennet for use inthe production of local cheeses as a substitute for animal-derived rennet. In Italy, the species has anextremely fragmented and localized distribution in six locations scattered across the central-northernApennines and some areas of southern Italy. In this study, both the morphology and genetic diversityof the six known Italian populations were investigated to detect putative ecotypes. To this end,33 morphological traits were considered for morphometric measurements, while genetic analysis wasconducted on the entire genome using the ddRAD-Seq method. Both analyses revealed significantdifferences among the Apennine populations (SOL, COL, and VIS) and those from southern Italy(ROT, PES, and LEC). Specifically, the southern Italian populations appear to deviate significantly insome characteristics from the typical form of the species. Therefore, its attribution to O. tauricum iscurrently uncertain, and further genetic and morphological analyses are underway to ascertain itssystematic placement within the genus Onopordum.
