Overview of flavonoid, lipid, and acetyl-CoA metabolism in Arabidopsis. Cell compartments represented include mitochondria (orange), chloroplast (green), endoplasmic reticulum (yellow), peroxisome (blue), the nucleus (gray), and the cytosol (white). Enzymes in the pathway proposed in this work are highlighted in red. OAA, Oxaloacetate; ECH, enoyl-CoA hydratase; HCD, hydroxyacyl-CoA dehydrogenase; PAL, Phe ammonia lyase; C4H, cinnamate 4-hydroxylase; 4CL, 4-coumarate:coenzyme A ligase; CHS, chalcone synthase.
