“…Further, it is clear that the niche of a lineage changes concomitant with a pollinator shift, permitting it to explore a new adaptive zone, which can lead to additional species diversification. This has happened repeatedly within the centropogonids, and is associated with the origin of radiations within the larger clade that do not experience frequent pollinator shifts (e.g., Burmeistera; Uribe-Convers et al 2017).…”

Although specialized interactions, including those involving plants and their pollinators, are often invoked to explain high species diversity, they are rarely explored at macroevolutionary scales. We investigate the dynamic evolution of hummingbird and bat pollination syndromes in the centropogonid clade (Lobelioideae: Campanulaceae), an Andean-centered group of ∼550 angiosperm species. We demonstrate that flowers hypothesized to be adapted to different pollinators based on flower color fall into distinct regions of morphospace, and this is validated by morphology of species with known pollinators. This supports the existence of pollination syndromes in the centropogonids, an idea corroborated by ecological studies. We further demonstrate that hummingbird pollination is ancestral, and that bat pollination has evolved ∼13 times independently, with ∼11 reversals. This convergence is associated with correlated evolution of floral traits within selective regimes corresponding to pollination syndrome. Collectively, our results suggest that floral morphological diversity is extremely labile, likely resulting from selection imposed by pollinators. Finally, even though this clade's rapid diversification is partially attributed to their association with vertebrate pollinators, we detect no difference in diversification rates between hummingbird- and bat-pollinated lineages. Our study demonstrates the utility of pollination syndromes as a proxy for ecological relationships in macroevolutionary studies of certain species-rich clades.

“…The result of the AU test also demonstrated the non-monophyly of the Fargesia grossa clade and the Fargesia macclureana clade. The use of whole plastid genome sequences has the potential to increase the resolution of phylogenetic analyses at low taxonomic levels or among recently diverged species (Njuguna et al, 2013; Williams et al, 2016; Sancho et al, 2017; Uribe-Convers et al, 2017; Fonseca and Lohmann, 2018). Taxon sampling (including ingroups and outgroups) is important for phylogenetic inference, particularly for the complex temperate woody bamboos.…”

“…Thus, a high-quality phylogeny, including more representative taxa and a large number of genetic markers, is necessary to understand the evolutionary history of Fargesia . Full plastome sequencing has been shown to be useful in resolving complex evolutionary relationships in closely related species (Njuguna et al, 2013; Williams et al, 2016; Uribe-Convers et al, 2017; Fonseca and Lohmann, 2018). Despite the existence of previous phylogenetic analyses based on the plastomes of Arundinarieae (Ma et al, 2014; Attigala et al, 2016; Saarela et al, 2018), the phylogenetic relationships among Fargesia species are still poorly resolved.…”

Fargesia is ecologically and economically important in mountainous forests. Many Fargesia species are also important sources of food for some endangered animals such as the giant panda. Recent molecular phylogenetic analyses have revealed Fargesia as a polyphyletic group despite some unclear lineage affinities. In the present study, we reconstructed the phylogeny of Fargesia and its allies, including Thamnocalamus, Arundinaria (incl. Bashania ), Yushania, Indocalamus, Ampelocalamus and Phyllostachys , from a plastome sequence matrix that contained 20 Fargesia and five Yushania species as ingroups, 16 species from nine other bamboo genera plus Oryza sativa and Zea mays as outgroups. Fargesia and its allies were broken into eight clades. Several Fargesia species were clustered into the Thamnocalamus clade and the Drepanostachyum + Himalayacalamus clade that rendered the polyphyly of Fargesia . The remaining six clades, including the Fargesia spathe clade, the Phyllostachys clade, Arundinaria fargesii , the Ampelocalamus clade, the Fargesia grossa clade, and the Fargesia macclureana clade, were identified. Molecular phylogenetic analyses supported that Yushania should be included in Fargesia (s.l.) which had synapomorphy of expanded leaf sheaths in varying degree at the basis of inflorescences, and further divided into the Fargesia spathe clade, the Fargesia grossa clade, and the Fargesia macclureana clade. All sampled species of Yushania were nested within the Fargesia grossa clade. The probable model of the origin of the species in the Fargesia spathe clade with spathe-like leaf sheath syndrome was proposed. Moreover, the formation of the spathe-like leaf sheath syndrome may be correlated with cold climatic conditions in Quaternary. Our results provide new sight into the phylogenetic relationship within Fargesia .

“…Genome skimming via shotgun sequencing of total genomic DNA at relatively low coverage is an efficient approach to recover entire plastomes and nrDNA [47]. Recently, genome skimming has been widely employed to reconstruct the evolutionary relationship at lower taxonomic levels and among closely related species [51][52][53][54][55], as well as to investigate reticulate evolution in diverse plant clades [52,[56][57][58]. In this study, we generated plastome and nrDNA sequences from all currently recognized Paris species using genome skimming method.…”

Background: Paris (Melanthiaceae) is an economically important but taxonomically difficult genus, which is unique in angiosperms because some species have extremely large nuclear genomes. Phylogenetic relationships within Paris have long been controversial. Based on complete plastomes and nuclear ribosomal DNA (nrDNA) sequences, this study aims to reconstruct a robust phylogenetic tree and explore historical biogeography and clade diversification in the genus.Results: All 29 species currently recognized in Paris were sampled. Whole plastomes and nrDNA sequences were generated by the genome skimming approach. Phylogenetic relationships were reconstructed using the maximum likelihood and Bayesian inference methods. Based on the phylogenetic framework and molecular dating, biogeographic scenarios and historical diversification of Paris were explored. Significant conflicts between plastid and nuclear datasets were identified, and the plastome tree is highly congruent with past interpretations of the morphology. Ancestral area reconstruction indicated that Paris may have originated in northeastern Asia and northern China, and has experienced multiple dispersal and vicariance events during its diversification. The rate of clade diversification has sharply accelerated since the Miocene/Pliocene boundary.Conclusions: Our results provide important insights for clarifying some of the long-standing taxonomic debates in Paris. Cytonuclear discordance may have been caused by ancient and recent hybridizations in the genus. The climatic and geological changes since the late Miocene, such as the intensification of Asian monsoon and the rapid uplift of Qinghai-Tibet Plateau, as well as the climatic fluctuations during the Pleistocene, played essential roles in driving range expansion and radiative diversification in Paris. Our findings challenge the theoretical prediction that large genome sizes may limit speciation.
