Chromosomal Analysis of Macaw Female #315: Insights from Chicken Control Genes

This study explores the chromosomal configuration of Macaw Female #315, focusing on its synteny with chicken control genes. We observed significant gene signals on various GGA chromosomes and identified unique patterns, especially with GGA6 and GGA7. The analysis revealed distinctions in telomere placements and NOR chromosome characteristics compared to chickens and California condors. Our findings enhance the understanding of avian genetics and highlight the complexities of chromosomal structures across species.

Presentation Transcript

  1. Macaw #315, female

  2. GGA1 AMA1q,4,9q Chicken control

  3. GGA2 AMA2 GGA11 GGA11 GGA11 – AMAZ!!! GGA11 Chicken control GGA11 Red – GGA11 BAC pool

  4. GGA3 AMA3 Chicken control

  5. GGA4 AMA1p, 8q GGA11 GGA11 GGA11 – AMAZ!!! Chicken control Red – GGA11 BAC pool

  6. GGA5 AMA5q Chicken control Red: BAC P1H3 on GGA5 No signal on macaw

  7. GGA6 AMA6 segments Chicken control Red: FZF – GGA6

  8. GGA7 AMA6q Chicken control Red: FZF – GGA6

  9. GGA6 and GGA7 are Syntenic in macaw AMA6 GGA6 paint GGA7 paint 7 6 CHICKEN CONTROL Paint for GGA6 Paint for GGA7 BAC clone for GGA6 7 6 Macaw-GGA6 paint and BAC Macaw-GGA7 paint and BAC Chicken GGA6 BAC clone (CHY4 gene) gives clear signal in macaw!!! 6 7 Macaw-GGA6 and 7 paints and BAC 6 7

  10. GGA8 AMA7p,7qter and micros Chicken control

  11. GGA9 AMA7qmid Chicken control

  12. GGAZ AMAZ Female-#315 Male- Erica Chicken control (female) W W

  13. GGAW No signal Chicken control (female) No signal on macaw W chromosome – similar situation is with mammalian Y which , as a rule, does not give Zoo-FISH signal across diverged species.

  14. 5.8S, 18S, 28S rDNA 3 pairs of microchromosomes with NORs (Chicken and California condor have only one NOR chromosome) Chicken control – 1 NOR

  15. W Telomeres Macaw #315 Z Macaw has telomeres at chromosome ends only - no interstitial telomeric sites. Prominent number of Telomeric sequences are in microchromosomes W Z
