Putative negative biomarkers (switch genes) of WS in grapevine. a Genes that are differentially expressed between WW and WS leaves at each time point in both genotypes following the application of a t-test (p < 0.01) and a fold change filter (|FC| ≥2 between WS and WW leaves). b Heat cartography map. The plane identified by the two parameters Z and P is divided into seven regions each defining a specific node role. Each point represents a node in the correlation network in Additional file 7, and the color of each node corresponds to its average Pearson correlation coefficient value. Roles were assigned to each node in the correlation network according to the heat cartography. c Heat map representing the 298 switch genes representing putative key regulators of the transcriptome shift from WW to WS status in grapevine leaves. Expression was measured as the log2 intensity of each biological replicate. Each value was normalized on the median value of each row/gene and Pearson’s correlation distance was used as the metric
