  • a Phenotype shown in Figure 6Avi.

  • b Phenotype shown in Figure 6Avii.

  • c Phenotype shown in Figure 6Aviii.

  • d Phenotype shown in Figure 6Av, arrowheads.

  • e Percentage of shriveled seeds + aborted embryos + unnatural intervals.

  • f Calculated from the following formula: 1 − {Vcol × (1 − Ldm) × Vvti12}, where Vcol = 0.98 (viability in Columbia), Ldm = 0.25 (theoretical frequency of zig-1/zig-1 vti12/vti12 progeny), and Vvti12 = 0.96 (viability in vti12/vti12 progeny).

  • g Calculated from the following formula: 1 − {Vcol × (1 − Ldm) × Vvti11}, where Vcol = 0.98 (viability in Columbia; shown in this table), Ldm = 0.25 (theoretical frequency of zig-1/zig-1 vti12/vti12 progeny), and Vvti11 = 0.68 (viability in zig-1/zig-1 progeny).
