Title	Multi-omic characterisation as a tool to improve knowledge, valorisation and conservation of wild fruit genetic resources: the case of Arbutus unedo L
Description	The conservation of plant genetic resources (PGRs) is contingent on their current or potential use, so extending the knowledge about them is crucial for their valorization. The valorization and conservation of wild fruit PGRs are critical to ensure the maintenance of genetic and cultural heritage and to promote and develop of new perspectives on resource use. New strategies for characterizing PGRs are needed, and the omics approach can provide profound information that is still largely unknown. The strawberry tree (Arbutus unedo L.) is an underutilized, drought and fire-resistant species distributed in the Mediterranean area and its berries have large ethnobotanical use but were not usually consumed as fresh fruits. Although their phenolic profile and antioxidant capacity are known, they are not well characterised, particularly from a proteomic perspective. The aim of this work is the characterisation from a molecular viewpoint of two ecotypes of A. unedo (Campania and Sicily) to valorise a less known wild fruit PGR to encourage its preservation. Samples were collected from two different geographical areas to assess whether different geographical conditions could influence the characteristics of leaves and fruits at the three stages of ripening (green, veraison, red). Proteomic analysis identified 904 proteins, of which 122 showed significance along the ripening process. Some of these differentially abundant proteins, such as chalcone synthase, show a marked increase during ripening. From a proteomic perspective, there are no differences between the fruits from the two regions compared by the ripening stage. However, the pedoclimatic metabolic imprinting allowed the observation of good diversity in the metabolomic profiles between the two ecotypes, especially for anthocyanins and catechins, generally more abundant in Sicilian fruit, or the phenolic compounds more abundant in Campania fruit. Multi-omic characterisation enhanced the knowledge on a wild fruit plant species which shows specific adaptations and responses to the environment to be considered when addressing the issue of local agrobiodiversity.
