Fig. S1 Spatial autocorrelation statistics for genome size (GS) for the maize landrace and teosinte data.

Fig. S2 Quantile regressions between genome size (GS) and elevation when the teosinte samples are considered by subspecies rather than by gradient.

Fig. S3 Comparison between the observed and predicted genome size (GS) for maize (cultivated) and teosintes (wild), based on the linear partial least-squares regression (PLSR) model fitted without latitudinal and longitudinal information.

Fig. S4 Principal component analysis (PCA) with the teosinte populations labeled by subspecies rather than by their gradient of origin.
