Fig 3. Proposed regulation mechanism of flavonoid biosynthetic pathway by CsMYB5-1 in alfalfa.
CHS, chalcone synthase; CHI, chalcone isomerase; F3H, flavanone 3-hydroxylase; FLS, flavonol synthase; DFR, dihydroflavonol 4-reductase; ANS, anthocyanidin synthase; ANR, anthocyanidin reductase; MATE1, multidrug and toxin extrusion transporter; UGT, UDP-glucose: flavonoid glycosyltransferase; TT8, transparent testa 8. Genes significantly regulated by CsMYB5-1 were bold.
