Detailed Description

hidA206/+ third instar larvae show no defects in the field coverage and branching of the dendritic arbor in class IV dendritic arborizing neurons compared to controls but dendrite pruning of these neurons normally occurring during pupariation is in hidA206 heterozygote pupae.

Whid-A206/Df(3L)H99 have on average 5 "neurons medially located, just above antennal lobe" (mALs), comparable to 5 in wild-type females. The number in males (~30) is also unaffected.

Stage 16 mutant female Whid-A206/Df(3L)H99 mutant embryos have male-specific somatic gonadal precursors in the posterior of the gonad, although the cluster of these cells is slightly smaller than in wild-type males.

Homozygotes display significantly reduced viability. Pronounced defect in the morphogenetic movements of head involution which results, in part, from a failure of the dorsal fold to migrate anteriorly. Otherwise the segmented cuticle is normal and individuals reach advanced stages. There is less apoptosis when compared to wild type, most noticeably in the head region prior to completion of head involution.

Surviving transheterozygotes with Whid-A22 or Whid-A206 have an abnormal wing phenotype. The mutant wing appears opaque by comparison to wild type and occasionally contains trapped fluid. Transheterozygous males also possess improperly positioned terminalia. Some hemizygotes die before hatching and most of those that hatch possess properly formed cephalopharyngeal skeleton.

The dendritic field coverage defects and loss of terminal branches as well as the increased branch retraction rate observed in class IV dendritic arborizing neurons of third instar larvae expressing nosdsRNA.Scer\UAS.WIZ under the control of Scer\GAL4477 is suppressed by combination with a single copy of hidA206 as is the increased density of mitochondria in dendrites observed with the RNAi driven by Scer\GAL4ppk.1.9.

The dendritic field coverage and branching defects observed in class IV dendritic arborizing neurons of third instar larvae expressing pumHMS01685 under the control of Scer\GAL4477 is suppressed by combination wth a single copy of hidA206.

The dendritic arborization defects observed in class IV dendritic arborizing neurons of nos18/nos53 third instar larvae are suppresed by combination with hidA206.

ninaEP37H, ninaE17, Whid-A206/+ flies exhibit strong recovery of visual response to light stimulation.

A Whid-A206 heterozygous background suppresses the degree of rprUTR.Scer\UAS.T:Ivir\HA1-indued eye ablation.

The small wing and eye phenotypes caused by hpoScer\UAS.cUa overexpression, (through Scer\GAL4unspecified or Scer\GAL4C5) can be partially suppressed by heterozygosity for Whid-A206, indicating that hpo requires W for its action.

Comments

Mutant males can be ranked based on the severity of terminalia rotation: Df(3L)H99 > Whid-H109 > Whid-A22 > Whid-A206 > Whid-A329 > Whid-H89. The ranking is roughly similar to the one for the degree to which the alleles disrupt embryonic head development.
