Chrysanthemum morifolium is one of the most economically important and popular floricultural crops in family Asteraceae. flowers vary considerably terms colors shapes. However, molecular mechanism controlling development chrysanthemum floral shapes remains an enigma. We analyzed a cut-flower variety that produces normal capitula composed ray florets with normally developed pistils purple corollas mutant comprising green vegetative buds instead pistils.We conducted whole-transcriptome analysis differentially expressed genes (DEGs) using third-generation second-generation sequencing techniques. identified DEGs between to reveal regulators underlying differential development. Many transcription factors related photoperiod GA pathways, organ identity, anthocyanin biosynthesis pathway were capitula. A qualitative pigments indicated anthocyanins synthesized accumulated capitula, but not These results provide clues regarding basis replacement buds. Additionally, study findings will help elucidate mechanisms contribute techniques for studying regulation flower shape color, which may enhance breeding.The C. described herein indicates deficiency be mutation replaces floret Moreover, required florets.
