“…Morus notabilis is distributed in Yunnan and Sichuan provinces of China and is distinguished from other Morus species by its orbicular leaves, female flowers with long styles, and long syncarps (Figure 1; Table S1). This species has 14 chromosomes [65,66], but haplotype of a certain individual has six chromosomes [67] (due to mitotic chromosomes 5 and 7 fused to form meiotic chromosome 5, detailed in Xuan et al [67]), compared to other Morus species with 28 (e.g., M. alba [68], M. rubra [69]), 84 (e.g., M. serrata [70]), or even 308 (e.g., M. nigra [71]) chromosomes (Table S1). Xuan et al [67] inferred that chromosomal fission/fusion events resulted in the different basic chromosome numbers between M. notabilis and M. alba.…”

The mulberry genus, Morus L. (Moraceae), has long been taxonomically difficult, and its species circumscription has only been defined recently. This genus comprises ca. 16 species distributed across Asia and the Americas, yet its biogeographic history remains poorly understood. In this study, we reconstructed the phylogeny and explored the biogeographic history of Morus using a combination of newly generated and previously published Hyb-Seq data. Our nuclear phylogeny recovered three well-supported geographic clades of Morus and showed that M. notabilis (China) is sister to the American clade plus the Asian clade. Multiple reticulation events among species of Morus and extensive incomplete lineage sorting (ILS) likely explain the difficulties in inferring phylogenetic relationships within the genus. Divergence time estimation indicated that Morus originated at the Eocene–Oligocene boundary, and current lineages started to diverge during the early Miocene, there is ambiguity surrounding the ancestral area with the two most likely regions being Sino-Himalaya or the Americas. Biogeographic inference and the fossil record suggest that Morus might have experienced extensive local extinction events during the Tertiary. Morus has expanded its distributional range through two dispersals from the Sino-Himalayan and Sino-Japanese regions to Southeast Asia. In summary, our new phylogenetic scheme and the biogeographic history presented here provide an essential foundation for understanding species relationships and the evolutionary history of Morus.
