Tissue-preferred genes and their expression profiling among various developmental stages of tissues. A total of 13 genes were listed in each group of tissue-preferred genes. The first three genes in each group were formatted with red fonts, which were previously characterized and, therefore were used as reference genes. The remaining 10 genes were formatted with black fonts, which were identified in this study. The log₂-transformed expression value from normalized expression data were used for heat map analyses. Red, black, and green colors indicated that transformed expression values were <0, = 0, and >0, respectively, in the matrix. T1, roots; T2, mature leaves; T3, young leaves; T4, young inflorescence (up to 3 cm); T5, inflorescence (3–30 cm); T6, seeds.
