Molecular cloning and expression analysis of dystroglycan during Xenopus laevis embryogenesis.

abstract：:Although the molecular mechanisms directing anteroposterior patterning of the Drosophila embryo (long-germband mode) are well understood, how these mechanisms were evolved from an ancestral mode of insect embryogenesis remains largely unknown. In order to gain insight into mechanisms of evolution in insect embryogenes...
