Expression patterns of RhPR10.1 in different rose flower organs during various opening stages (A) and in rose petals in response to exogenous hormones (B). A, Se, sepal; St, stamen; Pi, pistil; Re, receptacle; Pe, petal. B, Eth, 10 µL L⁻¹ ethylene; CTK, 100 µm 6-BA; ABA, 100 µm ABA; GA, 80 µm GA₃; BR, 5 µm brassinosteroid. The petals at opening stage 2 were used as material. The results are the means of three biological replicates with standard deviations. Letters indicate significant differences according to Duncan’s multiple range test (P < 0.05), and asterisks indicate significant differences according to Student’s t test (*P < 0.05, **P < 0.01).
