Detailed Description

Statement

Reference

Embryos from vas¹ homozygous mothers fail to form pole cells and show impaired dorsal patterning (assessed by no. of ftz stripes).

(Dehghani and Lasko, 2016)

vas¹/vas^PH165 egg chambers are similar to wild-type, consisting of 15 nurse cells and an oocyte surrounded by a layer of follicle cells.

(Liu et al., 2009)

100% of eggs laid by vas¹/vas¹⁵, vas¹/vas⁶ or vas¹/vas⁷ females appear wild-type.

(Tomancak et al., 1998)

Strong abdominal defects.

(Ephrussi et al., 1991)

Absence of posterior pole plasm, polar granules and pole cells.

(Lehmann and Nusslein-Volhard, 1991)

Normal eggs. Embryos lack polar granules, pole cells and abdominal segments.

(Schupbach and Wieschaus, 1991)

Reduced posterior vas localization in the oocyte. vas protein is only detectable at the germarium stage of ovarian development. Females lay wild type numbers of eggs that develop into embryos lacking abdominal segments and pole cells.

(Lasko and Ashburner, 1990)

Homozygous embryos derived from homozygous females have no polar granules, fail to form pole cells and have deletions of abdominal structures. Posterior localization of vas and CycB transcripts is completely abolished.

(Raff et al., 1990)

Homozygous females produce embryos that fail to form pole cells, lack polar granules normally found at the posterior pole, and have deletions of abdominal segments.

(Schupbach and Wieschaus, 1986)

Embryos derived from mutant females completely lack pole cells and show deletions in the abdominal segments. The same phenotype is seen in embryos derived from homozygous or hemizygous females.

(Schupbach and Wieschaus, 1986)

maternal-effect lethal. Embryos from homozygous mothers exhibit a so-called 'grandchildless-knirps' phenotype: all eggs lack polar granules and no pole cells are formed; most of the embryos show large deletions of abdominal segments, whereby anterior parts of segment A1 become fused to posterior parts of segment A8. Telson elements are always present and relatively normal. Eggs have abnormal shape. Analysis of germ-line clones indicates that the mutation is germ-line autonomous (Schupbach and Wieschaus, 1986). Homozygous vasa males cannot be distinguished from wild-type males in viability and fertility.

The failure to form pole cells as well as the impaired dorsal patterning (assessed by no. of ftz stripes) observed in embryos from vas¹ homozygous mothers is partially rescued in progeny from vas¹;bel::vas^{vas.C.bel.T:Avic\GFP-EGFP} females.

(Dehghani and Lasko, 2016)

vas¹/+ enhances the primordial germ cell phenotype resulting from the overexpression of Scer\GAL4^{nos.UTR.T:Hsim\VP16}>Fsn^{Scer\UAS.T:Ivir\HA1}.

(Kugler et al., 2010)

More than 50% of vas¹/vas^PH165 ; mei-P26¹/mei-P26^fs1 egg chambers are tumorous and fail to differentiate nurse cells and oocytes. The double mutant egg chambers contain mostly early-stage cystocytes as they contain either punctate spectrosomes or branched fusomes.

(Liu et al., 2009)

nos^{nos.+2'ME-3X.T:Ivir\HA1} partially rescues the abdominal segmentation defect of embryos derived from vas¹/vas³ females; 2% of the embryos develop no abdominal segments, 53% develop 1-3 abdominal segments, 43% develop 4-6 abdominal segments and 2% develop 7-8 abdominal segments. The embryos do not have anterior defects. nos^nos.+1.+2' or nos^{nos.+2RO.T:Ivir\HA1} fail to rescue the abdominal segmentation defect of embryos derived from vas¹/vas³ females; 100% of the embryos develop no abdominal segments. The embryos do not have anterior defects.

(Bergsten et al., 2001)

The lack of abdominal segments seen in embryos derived from vas¹/vas³ females is rescued if the females also carry nos^{αTub84B.UTR.T:Ivir\HA1}, but not if they carry nos^{αTub84B.UTR.virTCE.T:Ivir\HA1} or nos^nos.+1.Hsp83.

(Crucs et al., 2000)

Embryos derived from vas¹/vas³ females carrying nos^nos.+2.Hsp83 or nos^{nos.+2-3X.T:Ivir\HA1} do not produce any abdominal segments. 98% of embryos derived from vas¹/vas³ females carrying nos^{nos.+2'.Hsp83} produce 7-8 abdominal segments and 58% of these embryos show loss of head or thorax structures. Embryos derived from vas¹/vas³ females carrying nos^{nos.+2'-2X.T:Ivir\HA1} develop 0-3 abdominal segments in 16% of cases, 4-6 abdominal segments in 51% of cases and 7-8 abdominal segments in 34% of cases. Embryos derived from vas¹/vas³ females carrying nos^{nos.+2'-3X.T:Ivir\HA1} develop 0-3 abdominal segments in 72% of cases and 4-6 abdominal segments in 28% of cases.

(Bergsten and Gavis, 1999)

vas¹;6xP{osk⁺108} embryos exhibit a vas cuticular phenotype, deletion of most abdominal segments. Embryos also fail to form pole cells.

(Parkhurst and Ish-Horowicz, 1991)

Injection of nos^N5 RNA into vas¹/vas³ embryos completely rescues the abdominal phenotype.

tor^hb1+hb2 transcripts fully rescue posterior and anterior development in vas¹ embryos.

(Wharton and Struhl, 1991)

In double mutants vas¹, fs(1)N¹² all abdominal segments are transformed to the eighth abdominal segment.

(Degelmann et al., 1990)

vas¹ mutant embryos can develop into larvae and adults with a normal abdominal pattern, provided that they lack functional maternal transcripts of hb.

Comments

The loss of pole cells and patterning defects (assessed by no. of ftz stripes) characteristic for embryos from vas¹ homozygous mothers is rescued in progeny from vas¹;vas^{Δ15-75.T:Avic\GFP-EGFP} females, almost fully rescued in the progeny from vas¹;vas^{Δ15-75.T:Avic\GFP-EGFP} females and partially rescued in embryos from vas¹;vas^{Δ15-75.T:Avic\GFP-EGFP} mothers: the loss of pole cells is not restored but the patterning defects are ameliorated.

(Dehghani and Lasko, 2016)

Expression of vas^{DQAD.Scer\UAS.T:Avic\GFP} using Scer\GAL4^{nos.UTR.T:Hsim\VP16} fails to rescue the infertility phenotype of vas¹/vas³ mutants.

When vas^{Scer\UAS.T:Avic\GFP} is expressed using Scer\GAL4^{nos.UTR.T:Hsim\VP16} in a vas¹/vas³ mutant background, it rescues infertility. The rescued embryos show normal segmentation patterns, very similar to those hatched from eggs laid by wild-type females.

(Xiol et al., 2014)

Maternal expression of vas^{5xAla.T:Avic\GFP} rescues the viability and primordial germ cell formation defect in vas¹/vas^PH165 embryos.

Maternal expression of vas^{cKa.T:Avic\GFP} rescues the viability and primordial germ cell formation defect in vas¹/vas^PH165 embryos.
