TreeMix analysis and geographical distribution of tropical japonica and cAus accessions: a Different geographical groups considered in the Treemix analysis. In Africa, tropical japonica accessions from the West African highlands and Madagascar. In Asia, from West to East, the main groups we considered are shown. The clusters are defined by geographical zone. Each coloured country holds at least one accession from the dataset used for the Treemix analysis. b Maximum likelihood tree inferred by Treemix in chromosome 6 for the different genetic (Oryza sativa japonica—Oryza sativa aus, Oryza glaberrima) and geographical (from Africa and Asia) subgroups. The yellow arrows between the taxa indicate gene flow events simulated by the model. c Residuals from the model used to obtain the tree
