Comments

The let-7 seed sequence (GAGGTAGTAGGTT) has been deleted from the progenitor construct.

(Sokol et al., 2008)

The P{W8,let-7-CΔlet-7} construct can rescue the male fertility and climbing defects of Df(2L)let-7-CKO1/Df(2L)let-7-CGKI adults. However, the rescued adults still show severely reduced locomotion and show partial defects in flight. Df(2L)let-7-CKO1/Df(2L)let-7-CGKI females rescued by P{W8,let-7-CΔlet-7} show severe defects in female fertility and oviposition.

(Sokol et al., 2008)

Df(2L)let-7-CKO1/Df(2L)let-7-CGKI adults rescued by the P{W8,let-7-CΔlet-7} construct still show abnormal persistence of the dorsal internal oblique muscles (these muscles decay during post-eclosion maturation in wild-type animals) and still show defects in the dorsal muscles and their neuromuscular junctions.
