Summary of eve-lacZ fusion gene. Panel A shows the 8 kb of eve 5' flanking sequences. This region has been shown to contain CRMs responsible for the initiation of stripes 2, 3 and 7 (MSE2, MSE3+7), as well as an auto-regulatory element responsible for refinement and maintenance of the seven stripes during gastrulation. Panel B shows the two MSE2-lacZ fusion gene clones used for the mRNA concentration measurements. This picture was adapted from Small et al.  Fig.1.
