Distinct [AT]-increase patterns of bread wheat at genome and polymorphic site levels. a [AT]-increase pattern model of bread wheat during domestication after allopolyploidization. For each subgenome of each species, adjacent percentages show [AT] values at levels of genome (upper) and polymorphic site (bottom). The percentages with background color indicate average [AT]-increase from wild to domesticated accession. b Comparison of [AT] values of each subgenome among bread wheat (Chinese Spring), durum (Svevo), wild emmer (Zavitan), and Ae. tauschii (AL8/78). Blue bars show the differences of [AT] values between bread wheat and wild emmer in A and B subgenomes, and between bread wheat and Ae. tauschii in D subgenome; red bars show the differences of [AT] values between durum and wild emmer; and green bars show the differences of [AT] values between bread wheat and durum. c The [AT] values across polymorphic sites of bread wheat and its wild progenitors (including bread wheat variety (V), landrace-west (L-W), landrace-east (L-E), durum (D), wild emmer (W), and Ae. tauschii (A)). Different letters above the violins indicate significant differences (p < 0.05) when analyzed by Duncan’s test
