Phenotypic Description (Red Book; Lindsley and Zimm 1992)

St-SD: Stabilizer of Segregation Distorter

Increases k value of SD chromosomes and by so doing decreases the male-to-male variability of k. Located to the right end of 2R and affects k either in coupling or repulsion to Sd. Decreases fecundity and temperature response of SD/+ males (Hartl, Hiraizumi, and Crow, 1967, Proc. Nat. Acad. Sci. USA 58: 2240-45; Hikawa, 1971, Jpn. J. Genet. 46: 75-82). Existence inferred from behavior of various recombinant SD chromosomes. Probit analysis by Miklos (1972) indicates that the phenotype results not from a single locus, but from the cumulative effects of several weak enhancers; variability in k values in SD/+ genotypes lacking St-SD shown algebraically to be the consequence of reduced k values [see also Hartl, 1976, Genetics and Biology of Drosophila (Ashburner and Novitski, eds.). Academic Press, London, New York, San Francisco, Vol. 1b, pp. 615-66].

Testis-specificity index

The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).

Other Comments

All naturally occurring SD chromosomes carry RanGap^SD and Rspⁱ. Typical SD⁺ chromosomes carry Rsp^s and its presence is sufficient to render a chromosome sensitive to the action of RanGap^SD. Some SD⁺ chromosomes carry Rspⁱ. To cause high levels of distortion, RanGap^SD requires the presence of a series of upward modifiers known as E(SD)^unspecified, St-SD^unspecified and M(Sd)^unspecified.

(Kusano et al., 2003)

St-SD is held in linkage disequilibrium with RanGap^SD by inversions in many native SD chromosomes.

(Temin, 1995)

Increases k value of SD chromosomes and by so doing decreases the male-to-male variability of k. Located to the right end of 2R and affects k either in coupling or repulsion to Sd. Decreases fecundity and temperature response of SD/+ males (Hartl, Hiraizumi and Crow, 1967; Hikawa, 1971). Existence inferred from behavior of various recombinant SD chromosomes. Probit analysis by Miklos (1972) indicates that the phenotype results not from a single locus, but from the cumulative effects of several weak enhancers; variability in k values in SD/+ genotypes lacking St-SD shown algebraically to be the consequence of reduced k values (see also Hartl, 1976).
