Figure 8. Two additional maize alleles likely generated by RET and re-replication.
(A) Structure of progenitor allele p1-vv-D103 (upper) and TDDCI allele P1P2-3 (lower). The p1-vv-D103 allele is carried on a chromosome 1–10 translocation; the brown line indicates DNA segment from chromosome 10. See text for details. Other symbols have the same meaning as in previous figures. (B) TDDCI structure of bz1-m4-D6856. The bronze-colored boxes indicate exons 1 and 2 (right to left) of the bronze1 gene on maize chromosome 9. The baseline shows the predicted structure of the progenitor of bz1-m4-6856. The dashed box encloses a hypothetical Ds element proposed to have been involved in the generation of bz1-m4-D6856 via RET. For animation, see Video 4. Other symbols as in previous figures. The structure of bz1-m4-D6856 is deduced from Dowe et al. (1990) and Klein et al. (1988).
