thorax & macrochaeta
Overexpression of dxhs.PB shortly after pupariation results in nearly bald flies. Remaining bristles show the normal set of external cells. Overexpression at later stages causes the formation of double sockets, also a cell fate change of the neuron into a sheath cell is observed.
Induces a complex array of mutant phenotypes affecting eye, wing and bristle morphology. Overexpression between 0-24 hours after puparium formation causes a rough eye phenotype characterised by irregular ommatidia and lens disruptions indicative of cell death. Overexpression during the first six hours of pupariation results in loss of external sensory organ structures on the thorax giving a bald phenotype. Expression 24 hours after pupariation results in a 'double socket' and 'double shaft/single socket' phenotypes. Overexpression at late third instar or prepupal stages causes an extra bristle phenotype. Expression 0-24 hours after pupariation causes wing vein gaps, expression 24-48 hours after pupariation causes thickened veins.
