Figure 5. Differentially expressed genes between diploid and autotetraploid apple plants as determined by qRT-PCR.

Figure 5

The relative expression levels of each gene are shown for the diploid (2x) and autotetraploid (4x) plants. (a) Gene expression differed between 2x and 4x 5-year-old apple plants. Using the 2x plants as a control, 0.52-fold downregulation was observed for AUX1, 0.45-fold for MdARF3, 0.3-fold for DWF4, 0.35-fold for BSK, 0.25-fold for GA2ox, 0.65-fold for DELLA and 0.74-fold for GID2 in the 4x plants; however, 2.6-fold upregulation of BKI1 and 4-fold upregulation of BIN2 were observed in 4x plants. (b) Gene expression differed between 2x and 4x 5-year-old apple plants. Using the 2x plants as a control, 0.1-fold downregulation was observed for AUX1, 0.3-fold for MdARF3, 0.3-fold for DWF4, 0.2-fold for BSK, 0.15-fold for GA2ox, 0.82-fold for DELLA and 0.75-fold for GID2 in the 4x plants; however, 2-fold upregulation of BKI1 and 3-fold upregulation of BIN2 were observed in the 4x plants.
