NOTE. No positively selected codon sites were detected for the wild grass samples “S1” and “S2”. Asterisks denote significant positive sites for the Iran samples on wheat.
a
With the exception of site 48, the same positively selected sites were detected using the program PAML (Table S3).
b
Because of the large number of negatively selected sites in some enzymes, the number of selected codons per total number of codons is given.
