RT-qPCR validation of the selected genes within the SDRs of chromosome D502 and D507 under drought and salt stress conditions. The heat map was visualized using the MeV_4_ 9_0 program. Red and blue indicate high and low levels of expression, respectively, while white indicates none expressed genes. a Heat map showing gene expression in the leaf tissue of G. klotzschianum. b Heat map showing gene expression in the leaf tissue of G. davidsonii, c Heat map showing gene expression in the leaf tissue of G. thurberi and d Heat map showing gene expression in the leaf tissue of G. trilobum. Drought and salt stress was imposed by supplementing the Hoagland nutrient solution with 17% PEG and 250 mL of NaCl solution, respectively
