Fig. 5.

Morphology of microspore-derived embryos (MDEs) produced by B. napus lines with altered BnSTM expression. MDEs were collected after 25 d in culture. MDEs obtained from the WT line (A) were characterized by two distinct cotyledons (arrows) (B). MDEs produced by antisense lines and with lower BnSTM expression were smaller (C) and often produced fused cotyledons (D). No morphological differences were observed in MDEs produced by lines overexpressing BoSTM. All scale bars=0.3 mm. (This figure is available in colour at JXB online.)
