The third intron of AIL6 confers expression throughout young flowers. a GUS stained I3F-AIL6m:GUS-3′ line 3 inflorescence with strong GUS activity throughout the inflorescence meristem and young flowers. b GUS stained I3R-AIL6m:GUS-3′ line 2 inflorescence with strong GUS activity throughout the inflorescence meristem and young flowers. c, d GUS stained I1F-AIL6m:GUS-3′ line 1 (c) and I1R-AIL6m:GUS-3′ line 4 (d) inflorescences. No GUS activity was detected. e, f GUS stained and sectioned I3F-AIL6m:GUS-3′ line 3 inflorescence under bright field (e) and dark field (f) illumination. g, h GUS stained and sectioned I3R-AIL6m:GUS-3′ line 3 inflorescence under bright field (g) and dark field (h) illumination. Size bars correspond to 1 mm (a–d) and 50 μm (e–h). IM inflorescence meristem and st 4 stage 4 flower
