Expression profiles of GmFKFs during development.
GmFKF1 (A) and GmFKF2 (B) gene expression were performed in leaves. The samples were collected in both LD (left panel) and SD (right panel). The developmental stages included U (fully opened unifoliolates) stage, T1 (fully opened 1st Trifoliolates) stage, T2 (fully opened 2nd Trifoliolates) stage, T3 (fully opened 3rd Trifoliolates) stage, T4 (fully opened 4th Trifoliolates) stage and T5/F (fully opened 5th Trifoliolates) stage. The gene GmUKN1 was used as a control and bars indicated standard deviation.
