“…To trace the biogeographic history of the subfamily, an ancestral range estimation was conducted using the R package BioGeoBEARS (Matzke, 2014) implemented in RASP (Yu et al, 2015, 2020) based on the MCMC chronogram mentioned above. We defined seven areas based on climatic and tectonic histories of continents and extant distributions of Polygonaceae (Shen et al, 2018): (A) Northwestern Palaearctic realm, (B) Eastern Palaearctic realm, (C) India‐Pacific realm, (D) African realm, (E) Australian realm, (F) Neoarctic realm, (G) Neotropical realm.…”

Many species of the subfamily Polygonoideae are economically important. However, phylogenetic relationships and taxonomic treatments of these species remain disputed. In this study, we used highly orthologous nuclear genes and plastome sequence variation extracted from transcriptomes from 98 species of 26 genera of Polygonaceae mainly from the subfamily Polygonoideae to construct a robust phylogeny. We discerned six successively diverged and well-defined clades and both nuclear and plastome phylogenies are highly consistent with each other in this subfamily. Phylogenetic relationships between all clades and subclades were well resolved within Polygonoideae. Our analyses revealed that the shrub tribe Atraphaxideae and the herbal genera Polygonum, Persicaria, and Fallopia are polyphyletic. The sampled species of Polygonoideae started to diversify around the Cretaceous/Tertiary boundary (70 Ma) when the global climate exhibited large oscillations. Further origins of more herbal and woody species were found to have clearly increased during later climatic oscillations. We found that woody habits, especially shrubs, originated multiple times from ancestral herbs in this subfamily.Local dry climates may have favored such habit shifts from ancestral herbs. Our results deepen our understanding of evolutionary diversification of Polygonoideae.

Populus not only has significant economic and ecological values, but also serves as a model tree that is widely used in the basic research of tree growth, physiology, and genetics. However, high levels of morphological variation and extensive interspecific hybridization of Populus pose an obstacle for taxonomy, and also to the understanding of phylogenetic interspecific relationships and biogeographical history. In this study, a total of 103 accessions representing almost all the wild species of Populus were collected and whole-genome re-sequenced to examine the phylogenetic relationships and biogeography history. On the basis of 12,916,788 nuclear single nucleotide polymorphisms (SNPs), we reconstructed backbone phylogenies using concatenate and coalescent methods, we highly disentangled the species relationships of Populus, and several problematic taxa were treated as species complexes. Furthermore, the phylogeny of the chloroplast genome showed extensive discordance with the trees from the nuclear genome data, and due to extensive chloroplast capture and hybridization of Populus species, plastomes could not accurately evaluate interspecies relationships. Ancient gene flow between clades and some hybridization events were also identified by ABBA–BABA analysis. The reconstruction of chronogram and ancestral distributions suggested that North America was the original region of this genus, and subsequent long dispersal and migration across land bridges were contributed to the modern range of Populus. The diversification of Populus mainly occurred in East Asia in recent 15 Ma, possibly promoted by the uplift of the Tibetan Plateau. This study provided comprehensive evidence on the phylogeny of Populus and proposed a four-subgeneric classification and a new status, subgenus Abaso. Meanwhile, ancestral distribution reconstruction with nuclear data advanced the understanding of the biogeographic history of Populus.
