Maximum likelihood gene trees based on two regions within ALS. Amaranthus clades are delimited with grey highlight indicating anomalous samples (see text). Values at each node indicate maximum likelihood bootstrap support (BS)/Bayesian inference posterior probability (PP) value. The branches of A. albus, A. blitoides, A. blitum, A. palmeri, A. spinosus and parts of A. tuberculatus were compressed.
