Figure 6From: Co-ordinate regulation of cytokinin gene family members during flag leaf and reproductive development in wheatDevelopmental stages of spike, carpel and seed samples used for mRNA quantification of cytokinin regulatory genes in wheat observed using SEM (A) and light microscopy (B-L). A, spike 0.5 cm in length; B, spike 2 cm in length; C, spike 10 cm in length; D, carpel 14 days before anthesis (dba); E, carpel 7 dba; F, carpel 1 dba; G, 1 day after anthesis (daa); H, 2 daa; I, 4 daa; J, 7 daa; K, 14 daa; L, 21 daa. a, anther; c, carpel; e, endosperm; f1-f5, florets 1–5 in a spikelet; fm, floral meristem; slm, spikelet meristem. Scale bars: A = 50 μm, B-E = 500 μm, F-K = 1 mm.Back to article page
