Expressioni

Tissue specificityi

High levels seen in the aleurone and scutellum after germination, while low levels are found in developing seeds.

Developmental stagei

Levels increase steadily throughout imbibition reaching maximum levels at day 7. During germination, levels increase from day 2, reach maximum levels at day 3 and decline after day 5.

Inductioni

By gibberellin A3 (GA).
