Fig. 4From: Temperature regulation of carotenoid accumulation in the petals of sweet osmanthus via modulating expression of carotenoid biosynthesis and degradation genesThe expression levels of carotenoid-related genes in petals of sweet osmanthus ‘Jinqiu Gui’ under different temperature treatments. S1: Linggeng stage; S2: Initial flowering stage; S3: Full flowering stage. Values with the different letters are statistically different according to Duncan’s multiple range test at P < 0.05Back to article page
