Expressioni

Developmental stagei

Maximum levels are found in 35 day old plantlets when the rosette is mature, consisting of 8-10 fully expanded leaves, and as the floral stem starts to form. This level remains constant during the further life span of the plant.

Inductioni

By dark adaptation. This gives a 20-fold increase in expression.
