Transcription of bmp2b gene when organizer Bmp signaling is blocked. WT embryos at the one-cell stage were injected with 105 pg Tg(-2,067gsc:tBr-gfp) or Tg(-2,272bmp2b:tBr-gfp) DNA and harvested at the shield stage for examining bmp2b expression by in situ hybridization. The ratio of embryos with representative expression pattern was indicated. Embryos were orientated with dorsal to the right. Note that tBr-GFP overexpression led to a reduction of bmp2b expression in the ventral and lateral regions while its expression in the organizer appeared unaltered.
