Abstract

The term "terroir" has 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.

摘要

“风土”一词已被广泛用于将不同的地理表型与受农业实践、土壤类型和气候影响的农产品感官特征联系起来。如今，地理标志标签已得到发展，以保障与特定风土相关的植物源食品的质量，这类食品通常被认为具有卓越的感官特性。由于农业生态系统的动态变化高度复杂，由植物、微生物和周围环境之间错综复杂的相互作用网络组成，识别风土指纹识别的关键分子成分仍然是保护食品商品的产地和安全面临的巨大挑战。此外，微生物组作为风土特征潜在驱动因素的作用一直被低估。在此，我们首次全面展示了与纳克索斯岛广受欢迎的受保护地理标志马铃薯的转录组、蛋白质组、表观基因组和宏基因组相关的多组学全景。
