Fig. 8

The putative floral development regulatory network of reblooming bearded iris. This regulatory network was modified and integrated from the transcriptome sequencing results of the circadian rhythm related genes, the flowering pathway (including vernalization and photoperiod pathways) genes and the growth related pathway genes. Dark-blue indicates a relative increase of expression, and light-blue represents a relative decrease of expression. T1-T6 represents the six developmental stages in Table 2. OB and RB represent once-bloomers and rebloomers, respectively
