Fig. 6

Expression of CsA-IPT5 transcripts and CsA-IPT5 protein in the stem node, the expression of total CsA-IPT5 transcripts in the internode of the first node below the cuttings and root at different time points after the second pruning. A-H The expression of total CsA-IPT5 transcripts (A), CsA-IPT5 splice variants (B-F), and CsA-IPT5 protein (G, H) in the stem node after the pruning. I The expression of total CsA-IPT5 transcripts in the root and internode at different time points after pruning. Data are means ±SD (n = 6 or 3). For each figure, asterisks indicate significant differences in each index between control and pruning at each time point (**P < 0.01; Student’s t-test). Except for figure H, letters indicate significant differences of gene expression for each treatment among different time points (P < 0.05, Duncan’s multiple range test) (A-F). For figure H, letters indicate significant differences of CsA-IPT5/Actin between control and pruning at each time point (P < 0.05, Duncan’s multiple range test)
