Fig. 4From: Transcriptome disclosure of hormones inducing stigma exsertion in Nicotiana tabacum by corolla shorteningEndogenous hormone synthesis and signal transduction pathways in corolla. (A) Heat map of the 15 differentially expressed genes in IAA, zeatin, GA, ABA, and JA synthesis and signal transduction pathways. The red colour of critical enzymes in the KEGG pathway indicates that related genes are upregulated in E3C, and the green colour indicates that related genes are downregulated. (B) Hormone levels of IAA, DHZ, GA, ABA, and JA in corolla tissues of the three tobacco lines at the S3 stageBack to article page
