Construct: The N terminal coding sequence of wor (from 47 nucleotides upstream of the translation start to codon 262) is fused toi the C terminal coding sequence of sna (from codon 240 to the stop codon). The two fragments are connected by 2 additional amino acids created by fusing the two fragments using an XhoI site. This is driven by a 2.8kb sna promoter.
sna::worsna.wor-sna is a non-suppressor of ventral furrow phenotype of sna18
