Leaf traits associated with flavonol glycoside genes in soybean

In the soybean (Glycine max (L.) Merr.), the gene combination Fg1 Fg3 is responsible for the glycosylation in the biosynthesis of kaempferol triglucoside (K9) in leaves. The presence of K9 is associated with reduction in chlorophyll content, specific leaf mass, photosynthetic rate and stomatal frequ...

Zusammenfassung:	In the soybean (Glycine max (L.) Merr.), the gene combination Fg1 Fg3 is responsible for the glycosylation in the biosynthesis of kaempferol triglucoside (K9) in leaves. The presence of K9 is associated with reduction in chlorophyll content, specific leaf mass, photosynthetic rate and stomatal frequency. Blocking the action of Fg1 Fg3 with the magenta flower gene wm prevents formation of K9 and restores leaf traits to normal. A direct effect of K9 on leaf development is postulated.
