Fig. 2. Expression patterns of gARF6, mARF6, gARF8
and mARF8 protein:GUS fusions, and MIR167 promoter::GUS
fusions. (A-E) gARF6:GUS. (F-J) mARF6:GUS.
(K,M) gARF8:GUS. (L,N)
mARF8:GUS. (O-T) PMIR167a::GUS.
(U,V) PMIR167b::GUS. (W,X)
PMIR167c::GUS. (Y)
PMIR167d::GUS. (A,B) gARF6:GUS staining patterns
in stage 11 (A) and stage 13 (B) flowers. (C-E) gARF6:GUS expression
in stage 2-III (C), stage 3-I (D) and stage 4-I (E) ovules. Arrows indicate
funiculus. (F,G) mARF6:GUS expression in stage 11 (F) and stage 13
(G) flowers. (H-J) mARF6:GUS expression in ovules. Ovule development
stages in H,I,J are equivalent to those in C,D,E, respectively. (K)
gARF8:GUS staining in a stage 13 flower. Arrow indicates stamen
filament expression. (L) mARF8:GUS staining in a stage 13 flower. (M)
gARF8:GUS staining in a stage 4-I ovule funiculus (arrow). (N)
mARF8:GUS expression in a stage 4-I ovule. Arrow indicates reduced
outer integument growth. (O) PMIR167a::GUS expression in a
stage 13 flower. (P-R) PMIR167a::GUS in stage 1-II (P),
stage 2-III (Q) and stage 3-IV (R) ovules. (S,T)
PMIR167a::GUS expression in floral stage 10 (S) and stage
13 (T) anthers. (U,V) PMIR167b::GUS expression in a stage
13 flower (U) and a stage 4-I ovule (V). (W,X)
PMIR167c::GUS expression in a stage 13 flower (W) and a
stage 4-I ovule (X). (Y) PMIR167d::GUS expression in a
stage 13 flower. Scale bars: 0.3 mm in A,B,F,G,K,L,O,U,W,Y; 12 µm in C-E,
H-J,M,N,P,R,V,X; 30 µm in Q,S,T.
