Flower development of xi-1/xi-2/xi-k . A) Scanning electron micrographs of stage 12 flower buds of wild type (WT) and xi-1/xi-2/xi-k. Epidermal surface of the stigma has papillar structure. Note that stigmatic papillae (Sp) of xi-1/xi-2/xi-k are shorter than those of WT. B) Scanning electron micrographs of stage 14 flowers of xi-1/xi-2/xi-k. As xi-1/xi-2/xi-k flowers develop heterogeneously, both well developed (pollinated) as well as underdeveloped flower is shown. In the case of underdeveloped flower the development of whole pistil is retarded. Arrows indicate the retarded growth of the pistil, arrested in developmental stage 10. On the left panel: overall view of the flower. Bar = 500 μm. On the right panel: close-up view of the pistil. Bar = 100 μm. Sp – stigmatic papillae.
