Chronogram and heatmap of nonsynonymous substitution rates (dN) in protein-coding genes. a Time-calibrated tree of Gastrodieae. Green star indicates the loss of IR; yellow star indicates the loss of matK and trnW-CCA; red star indicates the loss of matK. b Heatmap of dN for each plastid protein-coding gene. Gray and red colors indicate low and high dN values, respectively
