Caenorhabditis elegans cog-1 locus encodes GTX/Nkx6.1 homeodomain proteins and regulates multiple aspects of reproductive system development.

abstract：:Cis-regulatory modules (CRMs) control spatiotemporal gene expression patterns in embryos. While measurement of quantitative CRM activities has become efficient, measurement of spatial CRM activities still relies on slow, one-by-one methods. To overcome this bottleneck, we have developed a high-throughput method that c...
