Detailed Description

Homozygous pum13 significantly blocks or reduces tolerance to both benzyl alcohol and ethanol.

The notum of homozygous pum13 flies display extra macrochaetae. The penetrance of the notum phenotype is incomplete.

pum13 mutants show abdominal defects in the larva. Medial protrusions and exposed sclerites are also seen in the larva head. Head skeleton defects and head involution defects are seen. 95% of homozygous larvae fail develop the normal mouth hook projection. 98% of pum13/pum1 larvae fail to develop the normal mouth hook projection.

Most embryos laid by pumMsc/pum13 mothers have 2 or 3 abdominal segments rather than the normal 8.

Germ cells are present in embryos derived from homozygous females.

Embryos derived from homozygous embryos have 0 to 2 abdominal segments. This phenotype is largely rescued if the females carry pumnos.PB, and is slightly rescued if the females carry pumΔ2'.nos or pumΔ5'.nos. Most of the embryos derived from pum13/+ females carrying pumG1330D.nos have abdominal segmentation defects.

Has no effect on the posterior accumulation of G-iα65A protein.

pum13 mutant embryos typically form only two abdominal segments. pum13;6xP{osk+108} embryos exhibit a wild type cuticular pattern and some hatch to produce viable adults.

Temperature sensitivity is restricted to the abdominal phenotype.

Does not interact with RpII140wimp maternal effect.

Large amounts of vas protein are expressed in early stages of oogenesis. vas protein localizes to the posterior pole at the same stage of egg development as wild type.

Homozygous embryos derived from homozygous females have polar granules and pole cells and have deletions of abdominal structures. CycB and vas transcript localization and accumulation is as in wild type.

Homozygous females produce embryos that have a maximum of two abdominal segments. The head, thorax and telson are normal, and pole cells are formed. Embryos derived from females mutant for both tslunspecified and pum13 develop several abdominal segments.

The ovariole/egg chamber defects observed in l(3)mbtGM76/Df(3R)ED10966 females are weakly and strongly suppressed by pum680 heterozygosity and homozygosity, respectively.

The frequency of the adolescent phenotype in animals expressing nosαTub84B.3'UTR.Scer\UAS under the control of Scer\GAL4sca-109-68 is not altered if they are also carrying pum13.

Injection of nosN5 RNA into homozygous embryos completely rescues the abdominal phenotype.

Comments
Comments

The abdominal phenotype of mutant embryos can be partially rescued by the injection of wild-type cytoplasm into the abdominal region. The rescuing activity acts directly at the site of injection and does not seem to spread; injections into the dorsal side of the prospective abdomen lead to the development of dorsal structures but leave the ventral side strongly mutant. Injections anterior and posterior to the abdominal region rarely lead to rescue. Rescuing activity is recovered only from the posterior pole of donor embryos. Cytoplasm transplanted from osk6 mutant embryos does not rescue the abdominal phenotype of pum13 mutant embryos.

hb protein expression in early pum13 mutant embryos has been studied.

The posterior localization of tud product is unaffected in mutant embryos.

Renamed from 'pum[13]' to 'pum[680]' to reflect the nomenclature that is: (i) used in the original publication (FBrf0047058); and (ii) much more commonly used in the published literature.
