Detailed Description

Statement

Reference

Sxl^fP7B0 heterozygous females do not display any decrease in viability compared to controls.

(Haussmann et al., 2016)

Sxl^fP7B0 heterozygotes are viable.

(Kappes et al., 2011)

Female viability is not compromised in a cross between wild-type females and Sxl^fP7B0 males.

(Li et al., 2011)

The viability of females carring Sxl^{N.Hsp83.T:Ecol\lacZ} is further reduced if they are also heterozygous for Sxl^fP7B0. Females carrying two copies of Sxl^{N.Hsp83.T:Ecol\lacZ} and heterozygous for Sxl^fP7B0 have reduced viability compared to females carrying one copy of Sxl^{N.Hsp83.T:Ecol\lacZ} and heterozygous for Sxl^fP7B0.

(Deshpande et al., 1999)

Sxl^fP7B0 is unable to suppress the sex comb defect seen in homozygous male U2af38⁰⁶⁷⁵¹ flies.

(Rudner et al., 1996)

Sxl^fP7B0/Df(1)N19 double heterozygous females have reduced viability; only 29% survive compared to control flies. Viability is recovered if the Sxl^fP7B0/Df(1)N19 females also carry Dp(1;3)JC153 or Sxl^M1. Sxl^fP7B0 shows no female-specific lethal interaction with Df(1)E128 or Df(1)os1A2. Sxl^fP7B0/+ ; In(2LR)Sco^rv1LTE35B-4^R/+ females have reduced viability at 29^oC.

(Sanchez et al., 1994)

Homozygous clones induced at blastoderm survive, differentiating male structures. Lethal in heterozygous combination with Df(1)N71 or Df(1)svr.

(Granadino et al., 1991)

Interacts with RpII140^wimp maternal effect.

(Parkhurst and Ish-Horowicz, 1991)

Sxl^fP7B0/snf¹ female progeny are more viable at lower temperatures. Sxl^fP7B0/snf¹ flies showed some somatic sexual transformation: male sex combs among normal female bristles. Sxl^fP7B0/snf¹ flies were always female sterile as expression of Sxl⁺ in the germline is required for female fertility. At 29^oC the ovarian tumours of Sxl^fP7B0/snf heterozygotes are snf-like (egg chambers have no nurse-like cells) and at 20^oC they are Sxl-like (egg chambers have an excessive number of nurse cells).

(Oliver et al., 1988)

Fails to complement Sxl alleles that are defective in somatic function, suggesting that this allele probably eliminates all known somatic functions. Fails to complement Sxl^f2, an allele defective in germline function.

(Salz et al., 1987)

nulls female-lethal male viable male-fertile males display normal male sexual behavior.

When da² or Flacc^A heterozygous mothers are crossed to Sxl^fP7B0/Y fathers only 53% and 38%, respectively, of the expected Sxl^fP7B0/+ female progeny survive to adulthood.

(Guo et al., 2018)

Sxl^fP7B0;msl-2²²⁷/Df(2L)Exel7016 females do not display any decrease in viability compared to controls.

Ime4^Δ22-3;Sxl^fP7B0 double heterozygous daughters from Ime4^Δ22-3 mutant females show strongly reduced female viability and tumorous ovaries (no decrease in viability or ovarian defects are observed in the presence of maternal wild-type copy of Ime4). The reduced viability phenotype can be fully rescued by combination with msl-2²²⁷/Df(2L)Exel7016 although these females frequently show signs of sexual transformation and display male-specific features such as sex-combs, which are mosaic to various degrees.

Sxl^fP7B0;YT521-B^MI02006 double heterozygous daughters from YT521-B^MI02006 mutant females show reduced viability and sexual transformations such as male abdominal pigmentation.

(Haussmann et al., 2016)

Ime4^null/+, Sxl^fP7B0/+ females, but not males, exhibit severely reduced survival to hatching, as compared to controls.

(Lence et al., 2016)

Removing one copy of Rbp9^P2690 during oogenesis in combination with zygotic heterozygosity for Sxl^fP7B0 results in female lethality. No female lethality is seen in the reverse cross. This female lethality is suppressed when msl-3¹ is also zygotically removed.

(Zaharieva et al., 2015)

Females trans-heterozygous for Sxl^fP7B0 and dm¹ are approximately two-thirds as viable as their dm¹/+ siblings.

Females trans-heterozygous for Sxl^fP7B0 and dm^P0 are approximately two-thirds as viable as their dm^P0/+ siblings.

Females trans-heterozygous for Sxl^fP7B0 and dm^P1 are approximately two-thirds as viable as their dm^P1/+ siblings.

Sxl^{N.Hsp83.T:Ecol\lacZ} females that are trans-heterozygous for Sxl^fP7B0 and dm¹ are two-thirds as viable as their Sxl^{N.Hsp83.T:Ecol\lacZ} Sxl^fP7B0/+ sisters.

Transgenic females trans-heterozygous for Df(1)dm75e19 and Sxl^fP7B0 are only half as viable as Sxl^fP7B0 female siblings.

(Kappes et al., 2011)

Sxl^fP7B0 suppresses the semi-lethality of homozygous cav²²⁴⁸ males.

In progeny from Su(var)205⁵ heterozygous females crossed to Sxl^fP7B0/Y males, female viability is dramatically reduced. The effect of Su(var)205⁵ is strictly maternal; no significant reduction in female viability is observed in the reciprocal cross.

In progeny from Su(var)205⁴ heterozygous females crossed to Sxl^fP7B0/Y males, female viability is dramatically reduced.

In progeny from Su(var)205² heterozygous females crossed to Sxl^fP7B0/Y males, female viability is reduced.

(Li et al., 2011)

The viability of Sxl^fP7B0/+ females is significantly reduced if they also carry one maternally-derived copy of msl-1^L60, msl-2¹ or msl-3¹.

The viability of Sxl^fP7B0/+ females is not affected if they also carry one maternally-derived copy of mle¹.

The almost complete lethality of Sxl^fP7B0/+ females carrying a maternally-derived copy of msl-3¹ is significantly rescued (to 98.7% viability) by a maternally-derived copy of Sxl^M1.

(Penn et al., 2008)

If snf¹⁴⁸/snf¹⁴⁸, Sxl^cF1.otu females are crossed with Sxl^fP7B0 males only 6% of her Sxl^fP7B0/+ daughters survive. When mothers heterozygous for both snf^J210 and snRNP70K⁰²¹⁰⁷ are crossed with Sxl^fP7B0 males, a significant reduction in viability is seen in Sxl^fP7B0/+ daughters. When mothers heterozygous for both snf^J210 and U2af38^ΔE18 are crossed with Sxl^fP7B0 males, a significant reduction in viability is seen in Sxl^fP7B0/+ daughters. When mothers heterozygous for both snf^J210 and U2af50^XR15 are crossed with Sxl^fP7B0 males, no significant reduction in viability is seen in Sxl^fP7B0/+ daughters.

(Nagengast et al., 2003)

The preferential sensitivity of males to the lethal effects of expression of run^Scer\UAS.cLa under the control of Scer\GAL4^nos.PG is not suppressed by Sxl^fP7B0.

(Tracey et al., 2000)

When embryos are also mutant for nos^BN, the germ cells form two clusters instead of the one they form in single mutants for nos^BN.

(Deshpande et al., 1999)

Female Sxl^fP7B0/+ embryos are fully viable if their mothers are heterozygous for da², 80% viable if their mothers are heterozygous for snf^J210, but only 7% viable if their mothers are heterozygous for both da² and snf^J210. The weak interaction between Sxl^fP7B0 and snf^J210 is enhanced by Df(2R)Su(z)3-1.iy, Aats-asp^TW6, Aats-asp^TW3, Aats-asp^12-21R, Aats-asp¹ or Aats-asp^25-1R; the viability of female Sxl^fP7B0/+ embryos derived from mothers heterozygous for snf^J210 and one of Df(2R)Su(z)3-1.iy, Aats-asp^TW6, Aats-asp^TW3, Aats-asp^12-21R, Aats-asp¹ or Aats-asp^25-1R is reduced. The weak interaction between Sxl^fP7B0 and snf^J210 is enhanced by Aats-trp⁰³⁵⁵⁹, Aats-trp⁴⁴²⁰, Aats-trp^P-74, Aats-trp^P-28B or Df(3R)by10; the viability of female Sxl^fP7B0/+ embryos derived from mothers heterozygous for snf^J210 and one of Aats-trp⁰³⁵⁵⁹, Aats-trp⁴⁴²⁰, Aats-trp^P-74, Aats-trp^P-28B or Df(3R)by10 is reduced.

Lethal in female double heterozygous combination with fl(1)35³⁵. Females doubly heterozygous for fl(1)35⁴⁶ and Sxl^fP7B0 show 2.1% viability. Lethality of fl(1)35⁴⁶/Sxl^fP7B0 females can occur at embryonic or larval stages. The viability of Sxl^fP7B0 in female double heterozygous combination with l(1)43⁴³ is reduced.

(Yanowitz et al., 1999)

Sxl^F1.hs cannot rescue the lethal phenotype. One copy of the moderate class of Sxl^F1.hs insertion at 25^oC causes high numbers of intersex individuals, this number drops slightly at 29^oC. All values are higher than individuals carrying the insertion in an Sxl⁺ background. This same pattern is demonstrated with one copy of a strong Sxl^F1.hs insertion class but the number of intersexes are less.
