| Research Abstract |
To obtain a genome wide landscape of transcriptional activity in the simple chordate model Ciona intestinalis, we have conducted a large scale sequencing of 5' ends of their mRNAs by massively parallel sequencing using the Illumina Genome Analyzer. The obtained 5'-end sequences were then used to map transcription start sites (TSSs) on the genome. The data were also used to map 5'-ends of trans-spliced transcripts. These data have been used to determine the TSS of a trans-spliced gene and for genome-wide profiling of C. intestinalis promoters. Based on these data, we further analyzed cell type-specific gene regulatory mechanisms in vivo by examining function of transcription factors, cis-regulatory DNAs, and chromatin level interactions. Using medaka as a vertebrate model, we have revealed that physical interactions between upstream cis-regulatory regions of two adjacent genes are a widely conserved mechanism for spatially regulated transcription during embryogenesis.
