Figure 7From: Global nucleosome positioning regulates salicylic acid mediated transcription in Arabidopsis thaliana NPR1 plays distinct role in the nucleosomal remodeling around the core promoter region of the SA regulated genes. Figure shows average relative nucleosomal occupancy in Col-0 (c) and npr1-1 mutants (n) under untreated (w) and treated (s) conditions of three genes from each group after normalization with a set of five internal control genes and with SE. ‘*, #, ^, ≈ and Δ’ denote the significance of the change in nucleosomal occupancy values among Wt-Ct–Wt-SA, Wt-Ct–NPR1-Ct, Wt-Ct–NPR1-SA, Wt-SA–NPR1-SA and NPR1-Ct–NPR1-SA pairs respectively, as per Student’s t-test at p ≤0.05. No significant changes were found in the values among Wt-SA–NPR1-Ct pair in all groups. Complete Student’s t-test table has been given for all pair-wise comparisons among Wt-Ct, Wt-SA, NPR1-Ct and NPR1-SA for each gene class as Additional file 12.Back to article page
