The crc spt double mutant. (A) SEM of a crc spt double-mutant fruit showing that the carpels are largely unfused. The stigma (stg), ovules (ov) and replum (rep) are labeled. (B) Cross-section of a crc spt gynoecium of the lower part of a mature flower. The septum (sep), medial vascular bundle (mv), lateral vascular bundle (lv), and ovule (ov) are labeled. (C) SEM of a crc spt gynoecium at stage 8, showing that the carpels are largely unfused and curve inward. Scale bars in A-B represent 100 µm and the scale bar in C represents 25 µm. A-C: from Alvarez and Smyth 2002.
