Fig. 7. LMI1:GUS expression in whole-mount samples. (A-H) Bright-field (A,C-G) and differential interference contrast (B,H) images of ß-glucuronidase (GUS) reporter activity controlled by LMI1 regulatory regions. Stages assayed were young seedlings (A,B), older seedlings (C,D), young inflorescence with secondary inflorescences (E), and older inflorescences (F,G). A heart-stage embryo is shown in H. The inset in H depicts a torpedo-stage embryo. Hy, hypocotyls; L(y), young leaves; L(e), elongating leaves; Br, bracts; Sp, stipules; S, sepal; P, petal; St, stamen; Ca, carpel. Scale bars: white, 1 mm; black, 100 µm.
