KEGG pathway analysis of down-regulated DEGs shared by four rice varieties between 1 h before floret opening and floret opening. Red represents differentially expressed genes annotated to a ko node and up-regulated, and the green represents differentially expressed genes annotated to a ko node and down-regulated. The 4 digits in the box indicated the EC number of the enzyme. Solid arrows indicated the direction of biochemical reactions. Dashed arrows connected other related metabolic pathways. A Diterpenoid biosynthesis; B pentose and glucuronate interconversions; C Phenylpropanoid biosynthesis
