Summary of HMS qualitative mapping

HMS
loci
Location
(flanking markers)
Major evidence (lines and genotypes where fertility shifts)
1Rga-Antp28.3, quasi-sterile → fertile within D
44.5, quasi-sterile (C.1) fertile (C.2)
32.4, quasi-sterile (C) → → fertile (E)
2ninaE-Fsh44.5, quasi-sterile → fertile within A
Mapped and named as broadie (Tao et al. 2001)
32.4, quasi-sterile (A) → quasi-sterile (B) Embedded Image
3Akt1-Su(Hw)42.4, quasi-sterile → fertile within D
40.8, quasi-sterile → fertile within D
37.10, quasi-sterile → fertile within D, sex ratio (k) shifts from 0.72 to 0.48
Mapped and named as tmy (Tao et al. 2001)
4Ald-Mlc146.15, fertility increases gradually from quasi-sterile (A and B) to subfertile (C, D, and E).
46.4, fertility increases from C to D Embedded Image , although both are fertile.
The current location of HMS 4 is most parsimonious to explain the data, but several loci, each with smaller effects, are also likely.
5Hb-Rox 846.15, subfertile (G) → fertile (H) Embedded Image
46.4, subfertile (H) → fertile (I) Embedded Image
38.1, 30% of males siring progeny within F
6Distal to jan46.4, A → B Embedded Image , although both are subfertile
7Odh-CrcComparison of 46.4 and 46.15; the left end of 46.15 must carry HMS factor(s)
Also implicated in 37.10 as recombination distal to P37 increases fertility (A → B and C)
8P38-HMS 7Comparison of 46.15 and 46.9 and 46.4; the left end of 46.9 must carry HMS factor(s)
Also implicated in 46.9, quasi-sterile (A) → subfertile (B) Embedded Image
  • Arrows represent (1) fertility shifts between classes and (2) significant increases in fertility as detected by permutation test (Po indicated).
