Transcription profiling of Drosophila embryos blastula wild-type and haploid

ABSTRACT: In most embryos, the mid-blastula transition is a complex process featuring maternal RNA degradation, cell cycle pause, zygotic transcriptional activation and morphological changes. The nucleocytoplasmic (N/C) ratio has been proposed to control the multiple events at MBT. To understand the global transcriptional response to the changes of the N/C ratio, we profiled wild type and haploid embryos using cDNA microarrays at three developmental stages. Experiment Overall Design: For the diploid transcriptional profile, we prepared cDNA from hand selected wild-type embryos at cycle 13 interphase (15min after the nuclear division of cycle 12) and at early and late cycle 14 interphase (15min and 40 min after the nuclear division of cycle 13), respectively. For the haploid, cDNA was prepared from c
