Isoflavone levels in Arabidopsis impaired in flavonol production. (A–D) HPLC profiles of hydrolyzed extracts from leaves of the tt6/tt3 mutant and WT Ler with and without expression of soybean IFS (T₃ generation). (A) tt6/tt3. (B) tt6/tt3 expressing IFS. (C) Ler WT. (D) Ler expressing IFS. Compounds are: G, genistein; K, kaempferol; Q, quercetin. (E and F) Levels of flavonols (E) and genistein (F) in individual T₃ plants of Ler (eight designations) and tt6/tt3 (nine designations) expressing IFS. White bars, quercetin; black bars, kaempferol.
