However, the variation mechanisms of petal color in Sect. <i>Chrysantha</i> Chang remains largely unclear.<h4>Methods</h4>We conducted an integrated analysis of metabolome and transcriptome to reveal petal coloration mechanism in three species, which have different yellow tones petals, including <i>C. chuongtsoensis</i> (CZ, golden yellow), <i>C. achrysantha</i> (ZD, light yellow), and <i>C. parvipetala</i> (XB, milk white).<h4>Results</h4>A total of 356 flavonoid metabolites were detected, and 295 differential metabolites were screened.
