Heat map was created in R using the pheatmap package for representing SUMO1/SIZ1 accompanying ROS scavenging, proline biosynthesis and GABA shunt pathway genes expression in rose flowers during opening and senescence. Stage 1, closed buds; stage 2, closed and heavily pigmented bud; and stage 3, flower with their outer petal whorl just unfurled as commercial harvest stage, stage 4, sepals completely opened, petal starting to unfold (4 days after harvest); stage 5, petals completely unfolded (8 days after harvest); and stage 6, flower completely senesced with petal bluing (12 days after harvest).
