A wide foodomics approach coupled with metagenomics elucidates the environmental signature of potatoes

The term terroirhas been widely employed to link differential geographic phenotypes with sensorial signatures of agricultural food products, influenced by agricultural practices, soil type, and climate. Nowadays, the geographical indications labeling has been developed to safeguard the quality of plant-derived food that is linked to a certain terroir and is generally considered as an indication of superior organoleptic properties. As the dynamics of agroecosystems are highly intricate, consisting of tangled networks of interactions between plants, microorganisms, and the surrounding environment, the recognition of the key molecular components of terroir fingerprinting remains a great challenge to protect both the origin and the safety of food commodities. Furthermore, the contribution of microbiome as a potential driver of the terroir signature has been underestimated. Herein, we present a first comprehensive view of the multi-omic landscape related to transcriptome, proteome, epigenome, and metagenome of the popular Protected Geographical Indication potatoes of Naxos.

The term terroir is widely used to link geographical characteristics with sensory characteristics of agricultural food products. Geographical indications labeling has been developed to ensure the quality of plant-derived food that is linked to a specific terroir and is considered to have superior sensory properties. However, understanding the molecular components and the contribution of microbiome to the terroir signature remains a challenge. In this study, we provide a comprehensive view of the multi-omic landscape related to the Naxos Protected Geographical Indication potatoes, including transcriptome, proteome, epigenome, and metagenome.
