Understanding genotype by environment (GxE) interplays is highly complex and challenging, and often the outcome of the genetic responses to field performance is not straightforward also due to the difficulties to reach a precise definition of the E component in field studies. In this work, the transcriptome of commercially ripe berries of Cabernet sauvignon and Aglianico genotypes grown in open-field at three different sites of central-southern Italy (Campania, Molise and Sicily) was analyzed by RNAseq. These transcriptomic data were integrated with a comprehensive set of climatic indices, forming an “environmentome”, through Weighted Gene Co-expression Network Analysis (WGCNA). A total of 11,887 differentially expressed genes (DEGs) have been retrieved, most of them found in the Aglianico genotype, suggesting that Aglianico transcriptome is largely influenced by the environment. Furthermore , the comparisons involving the Sicilian site exhibited t...
