Heatmap of DEGs in petals of NAT disc floret and AT disc floret in the three floral development stages. The bar represents the scale of the expression levels of each gene (log₂FPKM) in the three stages as indicated by red/blue rectangles. Red rectangles represent the up-regulation of genes, and blue rectangles represent down-regulation. All genes in this list have a differential expression P-value < 10⁻⁵. Red triangles represent key up-regulated genes and green triangles represent key down-regulated genes. A. Transcriptions factor involved in two types of disc florets. B. DEGs of auxin signal transduction pathway. C. DEGs of ethylene signal transduction pathway. D. DEGs of jasmonate signal transduction pathway. E. DEGs of abscisic acid, brassinolide, and gibberellin signal transduction pathway
