Summary
[edit]
| Description | Figure 2. SCI1 expression during later stages of floral development (continuation of the stages shown in Figure 1). (A) SEM of a flower bud in which petals and anthers are emerging (advanced stage –8). Scale bar: 100 μm. (B) Bright-field microscopy showing a longitudinal section of a flower bud in a developmental stage equivalent to the one shown in (A). Scale bar: 100 μm. (C) In situ hybridization of a flower bud (advanced stage –8) with SCI1 antisense probe. Scale bar: 100 μm. (D) SEM of a flower bud at stage –7 (as defined by Koltunow et al., 1990), in which carpels are emerging. Scale bar: 200 μm. (E) A higher magnification view of the flower bud shown in (D), in which the fusion lines are visible (arrows). Scale bar: 50 μm. (F) In situ hybridization of a flower bud at stage –7/–6, with SCI1 antisense probe. Arrows point to ovary locules. Scale bar: 50 μm. (G,H) SEM of flower buds at stage –6; carpels fused at the base and not yet fused at the top. Scale bars: 50 μm (G) and 75 μm (H). (I) In situ hybridization of a flower bud at late stage –6, with SCI1 antisense probe. Scale bar: 100 μm. (J,K) SEM of flower buds at stage –5; carpels already fused at the top; the fusion region is a site of intense cell proliferation. Scale bars: 150 μm (J) and 100 μm (K). (L) In situ hybridization with SCI1 antisense probe of a flower bud at late stage –5; style beginning to form (arrow). Scale bar: 150 μm. Floral meristem (FM), sepals (S), petals (P), anther (A), carpels (C), carpel primordia (CP), ovary (O), young ovary (YO). |
