Construct: Deletion of 2.8kb fragment containing the neurogenic element and an adjacent 0.95kb fragment dispensable for normal ftz expression.
P{ftzK}; ftz13 embryos fail to express ftz in the CNS and have a normal or only mildly defective epidermal development (FBrf0049007).
ftz promoter fragment is the same as that used in the P{ftz/lacD} construct (FBrf0045785).
