Scheme of FIL Expression in the Vegetative Meristem and the Inflorescence Meristem.

(A) FIL expression in the vegetative meristem is shown in gray. In the vegetative meristem, FIL expression was detected first on the abaxial side of the precursor of a leaf primordium (P0) and continued to be present in cells on the abaxial side of the leaf primordium (P1) and in a young leaf (P2∼).

(B) FIL expression in the inflorescence meristem was observed on the abaxial side of a flower primordium at stages 0 and 1. The expression remained at the bottom of the primordium at stage 2, and FIL expression started on the abaxial side of sepal primordia formed at the top of a stage-3 flower.

FM, floral meristem; IM, inflorescence meristem; VM, vegetative meristem.
