Hierarchical clustering of chloride responsive transcripts in grapevine roots. Transcripts (rows) that changed in response to 50 MM Cl⁻ in at least one variety with a fold change ≥ ±1.41 (P <0.05) were clustered. The response of each grapevine variety (columns) was also grouped (dendrogram above). Log(2) fold changes not statistically significant were set to 0. Clusters of interest are shown to the right of the heatmap, and contain genes that responded uniquely in each variety (A, B and C). Expression profiles and enriched GO biological processes for each cluster are also shown to the right of the heat map. CS = Cabernet Sauvignon, 140 R =140 Ruggeri.
