The phenotype caused when shiK44A.Scer\UAS is expressed at moderate levels under the control of Scer\GAL4prd.RG1 can be rescued by co-expression of wgScer\UAS.cHa; the naked cuticle region in odd-numbered segments is restored to its normal expanse and the even-numbered denticle belts show a more normal degree of diversity. Expression of shiK44A.Scer\UAS under the control of Scer\GAL4en-e16E perturbs denticle type specification in the first three rows of denticles in each segment. The phenotype can be rescued by co-expression of wgScer\UAS.cHa.
Expression of wgScer\UAS.cHa under the control of Scer\GAL4prd.RG1 in wgl-17 embryos fully rescues naked cuticle in odd-numbered segments and substantially rescues denticle diversity in the epidermal cells adjacent to the Scer\GAL4prd.RG1 expression domain.
wgl-12/+ raised at the restrictive temperature fail to show the increase in ghost boutons seen in controls upon spaced 5X K[+] depolarisation. Expression of wgScer\UAS.cHa using Scer\GAL4C380 in the wgl-12/+ background rescues this phenotype.
