G to A nucleotide change at the second or third position of the wild type Trp codon leads to a nonsense mutation (exact site of mutation unspecified). The mutation was annotated at the second base of the codon.
In tgo3 homozygous embryos branching of the terminal cells is absent and no connections develop between each side of the tracheal dorsal trunk so the dorsal trunk does not form a continuous tubular structure. In addition, the transverse connectives misroute resulting in an absence of dorsal branches. There is also an absence of ganglionic branches in the ventral nerve cord in tgo3 homozygous embryos.
Dominant enhancer of the Df(3R)ss-D114.4/+ weak antenna to tarsus transformation phenotype.
