Fig. 2From: Intricate genetic variation networks control the adventitious root growth angle in appleAllelic variations and the expression patterns of MdIAA1, MdDREB2A, and MdHSFB3 in ‘BC’, ‘M9’ and their F1 hybrids. a-c Expression of MdIAA1 (a), MdDREB2A (b), and MdHSFB3 (c) by RT-qPCR (bar chart) and mean FPKM values (line chart) during adventitious root formation in hybrids with small (S) (13–0670, 13–0925, and 13–1611) and large (L) (12–1529, 12–1585, and 12–1830) RGAs, respectively. (D-F) Schematic of single nucleotide variations of MdIAA1 (d), MdDREB2A (e), and MdHSFB3 (f). (g) and (h) Box plots showing RGA differences of markers G122 (g) and SNP592 (h), respectively. Numbers of the hybrids are given in parentheses. Asterisks represent P < 0.05 by Dunnett’s multiple comparisonBack to article page
