Heatmap Clustering Analysis of Gene Expression in Wheat Cultivars Under Salinity Stress and GR24 Treatments. The heatmap illustrates the clustering of ion transport and antioxidant-related gene expression in sensitive (Tajan) and tolerant (Sistani) wheat cultivars under salinity stress levels (0, 15 dS/m NaCl) and GR24 foliar treatments (H1: 0 µM and H2: 10 µM). Differential expression patterns are represented by color intensity, revealing treatment-specific variations in gene activity.
