Fig. 2: qRT-PCR analysis of the expression level of RhMYB108.

a Expression profiles of RhMYB108 in the roots, stems, leaves, and petals of rose plants. b, c, d, e, f Expression profiles of RhMYB108 in the petals, receptacles, sepals, stamens, and pistils at various stages of flower opening. g Expression of RhMYB108 in response to exogenous hormones. ETH, 10 μL/L ethylene; JA, 100 μM MeJA; 1-MCP, 2 μL/L. The petals at stage 2 were used as materials in g. RhUBI2 was used as an internal control. Three independent biological repeats were tested, and the data are presented as the means ± SDs. The letters indicate significant differences according to Duncan’s multiple range test (P < 0.05).
