Phylogenetic and evolutionary analysis. (A,B) Gene conservation and gene family expansion and contraction in A. heterophyllus and A. altilis. The scale bar indicates 10 million years. The values at the branch points indicate the estimates of divergence time (mya), while the green numbers show the divergence time (million years ago, Mya), and the red nodes indicate the previously published calibration times. (C) The distribution of gene families among the model species and Artocarpus genus. (D) Distribution of 4DTv distance between collinearity gene pairs among A. heterophyllus, A. altilis, M. notabilis, and Arabidopsis thaliana.
