UASt regulatory sequences drive expression of HGTX.
abnormal neuroanatomy
fascicle
larval intersegmental nerve branch ISNb of A1-7
motor neuron
Expression of HGTXScer\UAS.cSa under the control of Scer\GAL4sca.PU results in enlargement and thickening of the ISNb and many more fascicles than normal at ectopic sites, in particular an increase in ventral motor neurons.
