Comparative genomic and evolution analysis of morus species. (a) A Venn diagram of specific and shared orthologs among 9 species; (b) Gene-based genome colinear comparison between M. macroura and M. alba. Conserved syntenic blocks are highlighted with grey color corresponding to the fourteen pseudo-chromosomes, indicating visible genome rearrangements occurred during evolution among morus species. (c) Phylogeny and divergence time analysis among 9 species. The divergence times among different plant species are labelled on the right (million years ago, Mya).To better visualize the branching patterns of Morus, the divergence distance between P. persica and F. chinensis was rescaled from 76 to 12. Similarly, the divergence time between F. chinensis and the common ancestor of Morus was adjusted from 31.218 to 9.218.
