Fig. 3. ERECTA, ERL1 and ERL2 are expressed in young
proliferating tissues in an overlapping but unique manner. Expression of
ERECTA::GUS (A,D,G,J,M), ERL1::GUS (B,E,H,K,N) and
ERL2::GUS (C,F,I,L,O) reporter genes in: a 14-day-old seedling (A-C);
inflorescence apices at lower (D-F) and higher (G-I) magnifications;
inflorescence meristem (J-L); and a stage 11 flower (M-O). Scale bars: 3 mm
for A-C; 2 mm for D-F; 0.5 mm for G-I; 50 µm for J-L; 0.2 mm for M-O.
