Reference

ftz13/+ first instar larvae only rarely have segmentation defects.

At 26.5oC, about 64% of ftz5/ftz13 animals survive to adulthood, while at 27.5oC, about 35% survive to adulthood. At 26.5oC, ftz5/ftz13 embryos show variable segmentation phenotypes, ranging from normal to having defects in three ftz-dependent denticle belts. At 27.5oC, 53.8% of ftz5/ftz13 embryos have segment defects, with 4.3% having 3 ftz-dependent segments affected.

Homozygous embryos lack the odd-numbered abdominal segments.

Mutant embryos are deficient for cuticular structures derived from the even numbered parasegments.

P{ftzK}; ftz13 embryos fail to express ftz in the CNS and have a normal or only mildly defective epidermal development (FBrf0049007).

Subtle reduction in rate of germ band extension.

The phenotype of fu41 ftz13 double mutants can be interpreted as an addition of the corresponding single mutant phenotypes.

Shows an extreme ftz phenotype when homozygous and in trans with ftz14.

Double mutants with prd4 display a complete lack of segmentation.

P{ftzK}; ftz11/ftz13 individuals die as embryos or larvae. 66% of P{ftzG}; ftz11/ftz13 individuals survive to adulthood. P{ftzK}; ftz11/ftz13 embryos are identified by weak segmentation defects in the CNS.

Odd numbered denticle bands missing.

The frequency of cuticular segmentation phenotypes in ftz13/+ first instar larvae is significantly enhanced in animals with a egl3e/egl1 mutant mother.

The segmentation defects seen in ftz5/ftz13 embryos at 27.5oC are dominantly enhanced by the following (in each case the % of embryos with segmentation defects followed by the % of embryos with at least 3 ftz-dependent segments affected are given in parentheses after the enhancing allele); ftz-f12478 (95.9%, 44.7%), ftz-f13443 (98.5%, 35.1%), ftz-f15308 (91.3%, 40.5%), Gug519 (100%, 90.2%), Gug1757 (89.7%, 55.1%), Gug3333 (98.7%, 98.0%), bek1 (92.5%, 61.9%), hth2232 (73.9%, 16.3%), E(ftz)2020 (72.4%, 11.2%), E(ftz)723723 (91.9%, 32.5%), E(ftz)14271427 (99.4%, 93.1%), E(ftz)18151815 (72.1%, 22.1%), E(ftz)18191819 (97.8%, 31.3%), E(ftz)21422142 (93.1%, 13.2%), E(ftz)29552955 (78.5%, 16.2%), E(ftz)31503150 (95.0%, 79.4%), E(ftz)32013201 (88.7%, 15.5%), E(ftz)40384038 (82.9%, 23.6%). how2455 dominantly suppresses the segmentation defects seen in ftz5/ftz13 embryos at 27.5oC; 26.2% of the embryos have segment defects and 1.5% have at least 3 ftz-dependent segments affected. E(ftz)42364236 dominantly suppresses the segmentation defects seen in ftz5/ftz13 embryos at 27.5oC; 39.0% of the embryos have segment defects and 1.2% have at least 3 ftz-dependent segments affected. The frequency of segmentation defects seen in embryos derived from a cross of bek1/+ males to females carrying homozygous bek1 germline clones is increased if the fathers also carry ftz13.

Comments

Expression of ftzK in a ftz13 background rescues the segmentation defects but does not rescue CNS function, as illustrated by the RP2 neurons, which fail to develop.

21 to 71% of ftz11/ftz13 flies are rescued to adulthood by ftz+tDa. 2 to 5% of ftz11/ftz13 flies are rescued to adulthood by ftzT263D. Larval cuticles of ftz11/ftz13 animals rescued by ftzT263D are indistinguishable from wild-type. ftz11/ftz13 flies are not rescued to adulthood by ftzT263A. Larval cuticles of ftz11/ftz13 animals carrying ftzT263A have pair-wise deletions of even-numbered parasegments. The penetrance of the phenotype is variable and defects in each ftz-dependent parasegment (PS) occur with a characteristic frequency. These range from the most to least frequently affected as follows: PS2 > PS6 > PS10 = PS4 > PS12 = PS14 > PS8.

Removes even numbered en stripes.

Mutant phenotype of the ftz13/ftz14 heterozygote can be rescued to adulthood by the P{ftz4} construct. Partial rescue is seen with P{ftz5} construct and its revertants and no rescue with the P{ftzΔHD} construct.
