WebApr 1, 2024 · The main structure of chromones is similar to that of flavonoids, regulation of the flavonoid genes can provide information on the chromone biosynthesis pathway (Tan et al., 2024). Expression patterns of flavonoid biosynthesis-related genes showed the expression levels of most of DEGs were higher in EW than OW. Chromone (or 1,4-benzopyrone) is a derivative of benzopyran with a substituted keto group on the pyran ring. It is an isomer of coumarin. Derivatives of chromone are collectively known as chromones. Most, though not all, chromones are also phenylpropanoids.
