Abstract The timely transition from vegetative to reproductive development is coordinated through the quantitative regulation of floral pathway genes in response physiological and environmental cues. function ethylene‐responsive element‐binding protein (ERF) transcription factors flowering chrysanthemum ( Chrysanthemum morifolium Ramat.) not well understood. Here, overexpressing CmERF110 flowered earlier than wild‐type plants, while those which was suppressed later. RNA‐seq results revealed that several involved circadian rhythm were transcribed differently transgenic plants plants. peak clock delayed. Yeast two‐hybrid screening interactors identified a FLOWERING LOCUS KH DOMAIN (FLK) homologue CmFLK, further confirmed with both vitro vivo assays. KEGG enrichment also CmFLK rhythm‐related genes. showed change time delayed Taken together, present data only suggest interacts promote by tuning clock, but provides evidence for evolutionary conservation components autonomous chrysanthemum.
