Figure 4.

Expression accumulation profiles of 10 woodland strawberry GRF genes in response to low temperature (4 °C), high temperature (42 °C), drought, NaCl, salicylic acid (SA), and abscisic acid (ABA) treatments as determined by quantitative RT-PCR analysis and displayed in the form of heat maps. The color scale indicates the change in expression level, where red indicates an increase and green indicates a decrease, relative to that at 0 h. The experiment was repeated three times and the results were consistent.
