ABA-related genes expression in the four genotypes in response to water deficit. a) Heatmap representation of the gene expression of ABA-related genes across the different conditions. For each condition (Organ x Week x Treatment x Genotype), an average TPM value was calculated and log2 transformed. These expression values are represented as Z-scores (calculated per gene) on the heatmap and are colored from turquoise (low value) to pink (high value). Genes were clustered by process or protein family labeled on the left. At the top of the heatmap, a chart identifies the different conditions with leaves and roots in light grey and dark grey, respectively; week 1 and week 2 in light grey and dark grey, respectively; control and drought treatment in light grey and dark grey, respectively; and the genotypes CS, RG, RM and SC in red, green, blue and purple, respectively. Expression profiles of NCED3 (b), RD26 (c), DHN1 (d) and GOLS2 (e) after two weeks of treatment. Expression in control (left column) and WD treated vines (right column) for the leaves (top row) and the roots (bottom row) is represented in transcripts per million, mean ± SE, n = three-five individual vines. Genotypes are color coded as for the heatmap (a)
