Detailed Description
Statement
Reference

Mutant embryos have defects in germband extension.

Homozygous or gnyf04215/Df(2L)BSC6 larvae hatch and have a wild type cuticle by light microscopy. They eventually die after one moult without displaying any obvious phenotype.

Removal of maternal gny in gnyf04215 germline clones results in larvae with patterning and morphological defects, the most prominent being the failure to form a normal head skeleton. The cuticle is discontinuous and the body contours are irregular. At the edges of ruptures, the cuticle is often melanized. Specialized cuticle structures such as denticles are present.

Removal of maternal and zygotic gny in gnyf04215 germline clones causes additional reduction in cuticle deposition and a complete failure of denticle formation and melanization.

gnyf04215, wol2 double mutant embryos fully develop into larvae that hatch and die at the second instar. Embryos derived from gnyf04215, wol1 double mutant germline clones show the same cuticle phenotypes as embryos produced from either single mutant germline clone.
