Sustained corolla formation in bisexual disc florets of anemone-type Chrysanthemum × morifolium depends on localized auxin enrichment, with CmARF6 and CmARF8.1 acting as positive regulators.
- Why it matters: Species-specific corolla shapes in Asteraceae require translating localized growth cues into distinct floral architectures, but the regulatory links were unclear.
- What they did: The study used anemone-type chrysanthemum to show that miR167 post-transcriptionally regulates CmARF6 and CmARF8.1 in a dose-dependent manner, activating CmYUC2 and CmPILS1 and stimulating proliferation via CmSAUR64 and CmSAUR76.
- The result: Comparative analyses across diverse Asteraceae species suggest auxin-associated regulatory mechanisms may contribute to region-specific corolla growth, providing a framework to study related morphological variation.
