Figure 7

Heat map showing temporal expression pattern of selected genes associated with enzymatic antioxidants, RNS biosynthesis, redox homeostasis, heat shock proteins and aquaporins in leaves of strawberry plants under non-stress and heat stress conditions. Following root pre-treatment with 100 μΜ NaHS, the experimental plants were grown either under normal (23°C) or extreme temperature (42°C) conditions for 8 h, as described in Figure 1. Relative mRNA abundance was evaluated by real-time RT-PCR using three biological repeats. Up-regulation is indicated in green; down-regulation is indicated in red. Diagonal dotted lines represent statistically significant values at p < 0.05. A scale of color intensity is presented as a legend. Actual relative expression data, obtained from 3 independent replicates, are shown in Additional file 1: Table S1.
