Construct: The N terminal coding sequence of sna (from 75 nucleotides upstream of the translation start to codon 239) is fused toi the C terminal coding sequence of sna (from codon 340 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.sna-wor is a suppressor of ventral furrow phenotype of sna18
