Comparison blast
The PROE amino-acid sequences showed a minimum coverage of 73%, with
the percentage of identity ranging from 61 to 81% and the percentage of
similarity from 68 to 88% (Table S1, supplemental data). The duck PROE
protein has an amino acid sequence closer to that of pigeons than geese.
The alignments of the IGLL1 amino-acid sequences showed a minimum
coverage of 99%, a percentage of identity ranging from 65 to 89%, and
a percentage of similarity from 77 to 89% (TableS1, supplemental data).
The IGLL1 proteins of goose and duck showed highly conserved amino-acid
sequences (Coverage: 100%, ID, 81%, SIM: 89%).
