Expression and functional analysis of UV-differentially expressed genes in Tempranillo berry skin. Expression heat-map of UV-differentially expressed genes (P <0.01 and |Fold change| ≥2 at least for one berry density) grouped according to a three k-means clustering. Row normalized Log₂ expression is represented for each sample. The number of transcripts, a summary of their significantly enriched functional categories (Benjamini-Hochberg adjusted P <0.05) and in a grey box, the transcription factors included are indicated in the right side of each cluster.
