Colour differences between cannabis accessions can be explained by differential expression of flavonoid biosynthesis genes #FlavonoidFriday https://lnk.tu-bs.de/8ubwTn
Cornflower vibrant color comes from a unique complex of anthocyanins, flavones, and metal ions (Fe³⁺, Mg²⁺), stabilized by pH. This metal-anthocyanin interaction shifts the color to blue. #FlavonoidFriday: https://lnk.tu-bs.de/9Zz2uG

Seed color patterns in beans are due to sequence variants in genes encoding components of the MBW complex #FlavonoidFriday: https://lnk.tu-bs.de/C0Mcgj
Strawberry has two DFRs with specific substrate preferences: DFR1 accepts only dihydrokaempferol, while DFR2 accepts only dihydroquercetin and dihydromyricetin. Resulting anthocyanins are orange/red or red/pink, respectively. Details: https://lnk.tu-bs.de/6pKrdf #FlavonoidFriday
