AGL6-like Expression in Young Spikelets of S. bicolor (Panicoideae) at Successively Older Stages of Development.

(A) Sb AGL6 in the floral meristem of both florets of sessile and pedicellate spikelets.

(B) Expression in palea and carpel primordia.

(C) Expression in palea, lodicules, and gynoecium.

(D) and (E) Two successive sections of the same spikelet.

(D) Expression in developing palea and lodicules.

(E) Expression in lodicules and gynoecium.

(F) Expression in the integument (arrowhead).

ca, carpel primordia; fi, filament of the stamen; gl, glume; gyn, gynoecium; le-f, fertile lemma; le-s, sterile lemma; lf, lower floral meristem; lo, lodicules; ra, rachilla; p-spk, paired spikelet; pa, palea; sta, stamens; uf, upper floral meristem. Bars = 100 μm.
