Preliminary study on search for genes for early embryonic development in goldfish by mRNA differential display

【摘要】：正 MATERNAL RNAs stored in eggs play an essential role during the initial stage of embryonic de-velopment in animals and they are degraded as the development proceeds. In some animals (e.g. fish and amphibian), zygotic genes begin to transcribe new mRNA only when the embryosdevelop to about midblastula stage. This degradation of maternal RNA and synthesis of zygotic
