Fig. 7. OsMADS45 expression in the wild type and spw1 dl-sup double mutant. (A) Wild-type vegetative shoot, (B) wild-type inflorescence shoots, (C) wild-type flower and (D) spw1-1 dl-sup1 flower (longitudinal sections). In wild type, the expression was detected in lodicules (arrowhead), stamens (st) and the carpel (ca), but not in vegetative or inflorescence shoots. In the mutant flower, the expression was detected in organs formed in whorl 2 and inner regions SAM, shoot apical meristem; le, lemma; pa, palea; st, stamen primordia. The numbers, 1 and 2, indicate the primary and secondary inflorescence meristems, respectively. Bar, 50 µm.
