Fig. 7

Heatmap representing the expression of differentially expressed candidate genes in response to Si application during drought stress in ILL 7537 in DSi vs. D treatment (p ≤ 0.05). The colour key represents the normalised log transformed counts. Red indicates low expression, black indicates intermediate expression and green indicates high expression. Each column represents an experimental condition, and each row represents a gene (p ≤ 0.05, ≥ 1.5-folds change). The significantly (P ≤ 0.05) enriched biological process GO terms are shown on the right side of each cluster. Abbreviations used in this Figure are DSi—Drought stress supplemented with Si and D—Drought stress
