Summary of different ZCCT-A1 and ZCCT-B1 alleles in a collection of wild T. turgidum subsp. dicoccoides, partially domesticated T. turgidum subsp. dicoccon, and modern cultivated T. turgidum subsp. durum
PI accessions are from the National Small Grain Collection (United States), and other numbers are population numbers from the University of Haifa. Numbers below the gene names indicate their positions within the CCT domain. All ZCCT-A1 and ZCCT-B1 proteins included here have an R at position 16. Bold letters indicate mutated amino acids.

Since the R16C mutation is fixed in ZCCT-A2 and ZCCT-Am2, we checked only one accession from each group for this mutation.
1 indicates that only one of the two polymorphic sites was detected but does not completely rule out the existence of the duplication.
