Virtual gel of the retrotransposon insertions detected in the 5S arrays.
Accessions are identified by the codes given in Table A in File S1. All T.timopheevii accessions displayed the same profile marked here as T.ti. Pink and orange arrows indicate insertions detected only in wild and domesticated tetraploid wheats, respectively. Combinations absent in wild populations but frequent in domesticated accessions are highlighted with a pink background. Accessions for which 5.8S-Jeli sequences were obtained are color-coded in the same way as the node outer circles in Figure 2.
