- Association Flower size of white-flowered alfalfa decreased by 18.9% relative to purple-flowered alfalfa.
- Association Chlorophyll a content of white-flowered alfalfa decreased by 46.0% relative to purple-flowered alfalfa.
- Association Gibberellin levels were reduced in white-flowered alfalfa.
- Association Jasmonic acid increased by 36.3% in white-flowered alfalfa.
- Association Proline increased by 51.5% in white-flowered alfalfa.
- Association Total flavonoids increased by 17.7% in white-flowered alfalfa.
- Association Condensed tannins increased by 18.2% in white-flowered alfalfa.
- Observation Multi-omics analysis revealed phenylpropanoid pathway reprogramming in white-flowered alfalfa, with suppressed anthocyanin biosynthesis and precursor accumulation.
- Observation Jasmonic acid signaling was activated in white-flowered alfalfa as part of coordinated hormone signaling.
- Observation Salicylic acid signaling was inhibited in white-flowered alfalfa as part of coordinated hormone signaling.
- Mechanism The authors conclude the white-flower trait is a key component of a coordinated adaptive syndrome mediated by metabolic reprogramming and hormonal crosstalk.
