abstract：:The sequence-specific DNA-binding protein, MyoD, can activate muscle-specific gene expression in some cells in culture. Xenopus MyoD (XMyoD) transcription is activated as a consequence of mesoderm induction in the early myotomes, from which the axial musculature develops. XMyoD RNA accumulates about two hours before m...
