Figure 1.
Conventional karyotype of Asturina nitida (A), Rupornis magnirostris (B) and Buteogallus meridionalis (C).
Figure 2.
18S-45SrDNA probes (green) and telomeric probes (red) in Asturina nitida (A and B), Rupornis magnirostris (C and D) and Buteogallus meridionallis (E and F).
Note that in (A) and (C), NOR-bearing chromosomes are associated. Arrows show interstitial telomeric sequences.
Figure 3.
Representative FISH experiments using whole chromosome probes derived from Gallus (GGA) onto Buteogallus meridionallis (BME), Asturina nitida (ANI) and Rupornis magnirostris (RMA).
Figure 4.
Homology map between Buteoninae karyotype and chicken paints.
Correspondences are indicated by colors. White sections represent segments not hybridized by any of the applied probes.
Table 1.
Homoeologous chromosomal segments in birds of prey as detected by FISH experiments using whole chromosome probes (wcp) derived from chicken (GGA): Harpia harpyja (HHA); Gyps fulvus (GFU), G. rueppelli (GRU); Gypaetus barbatus (GBA); Buteoninae (BUT) and Falco peregrinus (FPE).
Figure 5.
Whole chromosome probe derived from L. albicollis which corresponds to a fusion GGA1p/GGA6, confirming this rearrangement as a synapomorphy shared by Buteoninae species.
Asturina nitida (A), Rupornis magnirostris (B) and Buteogallus meridionalis (C). In (D), an experiment using the same probe onto Gallus gallus metaphase chromosomes.
