KEGG pathway analysis of up-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, 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 Plant hormone signal transduction; B MAPK signaling pathway-plant; C alpha-Linolenic acid metabolism; D plant–pathogen interaction; E starch and sucrose metabolism
