Polyploidization is a major driver of speciation and its importance to plant evolution has been well recognized. Bamboos comprise of one diploid herbaceous and three polyploid woody lineages, and are the only major subfamily in grasses which diversified in forests with tree-like lignified culm for its woody members. Here we generated four draft gen...

Rapid evolutionary radiations are among the most challenging phylogenetic problems, wherein different types of data (e.g., morphology, molecular) or genetic markers (e.g., nuclear, organelle) often yield inconsistent results. The tribe Arundinarieae i.e., the temperate bamboos, is a clade of tetraploid originated 22 million years ago and subsequent...

The grass family (Poaceae) includes all commercial cereal crops and is a major contributor to biomass in various terrestrial ecosystems. The ancestry of all grass genomes includes a shared whole-genome duplication (WGD), named rho (ρ) WGD, but the evolutionary significance of ρ-WGD remains elusive. We sequenced the genome of Pharus latifolius, a gr...

Background Flowering plants (angiosperms) are dominant components of global terrestrial ecosystems, but phylogenetic relationships at the familial level and above remain only partially resolved, greatly impeding our full understanding of their evolution and early diversification. The plastome, typically mapped as a circular genome, has been the mos...
Article
Geographical names and the entities they represent act as a fundamental cornerstone across numerous disciplines. However, inconsistent geographical names and arbitrarily defined regional geographical scales are common, hindering cross-disciplinary communication and synthesis. The Pan-Tibetan Highlands, comprising the Tibetan Plateau, Himalaya, Heng...

Cymbidium is an orchid genus with rapid radiation and high ornamental, economic, ecological and cultural importance, but its classification is controversial based on morphology. The plastid genome (plastome), as an extension of plant standard DNA barcodes, has been widely used as a potential molecular marker for identificating the recently diverged...
Article
Polyploids are common in Camellia sect. Paracamellia, which contain many important oil crop species. However, their complex evolutionary history is largely unclear. In this study, 22 transcriptomes and 19 plastomes of related species of Camellia were sequenced and assembled, providing the most completed taxa sampling of C. sect. Oleifera and C. sec...
Article
Mycorrhiza play key roles for ecosystem structure and functioning in forests. However, how different mycorrhizal types influence mountain forest biodiversity–ecosystem functioning (BEF) relationships are largely unknown. We evaluate how the diversity of distinct mycorrhiza‐associated fungi and trees shapes forest carbon storage along elevational gr...

The taxonomy of the Sino-Himalayan alpine bamboos is controversial due to their complex evolutionary history and further complicated by the scarcity of inflorescence. Here, we supplement the description of the inflorescence of Fargesia angustissima T.P. Yi and Yushania pauciramificans T.P. Yi, which shed light on the taxonomy of Fargesia Franchet,...
Article
Long-distance dispersal (LDD) beyond the range of a species is an important driver of ecological and evolutionary patterns, but insufficient attention has been given to postdispersal establishment. In this review, we summarize current knowledge of the post-LDD establishment phase in plant colonization, identify six key determinants of establishment...

The evolution of subtropical evergreen broadleaved forests (EBLFs) in East Asia is interesting while complicated. Genus-level phylogenies indicate that the origins of EBLFs could trace back to the Oligocene–Miocene boundary or even the Eocene, while population-level phylogeographic evidence suggests that they diversified after the Miocene, particul...

The Convolvulaceae is a pantropical family with high morphological diversity and economic values. To date, however, the phylogenetic relationships among the major lineages or tribes in the family have not been fully resolved. In order to resolve these relationships, we sampled the complete plastome sequences from 40 species, representing eight reco...

The millions of herbarium specimens in collections around the world provide historical resources for phylogenomics and evolutionary studies. Many rare and endangered species exist only as historical specimens. Here, we report a case study of the monotypic Pseudobartsia yunnanensis (= Pseudobartsia glandulosa: Orobanchaceae) known from a single Chin...

Sexual dimorphism in dioecious plants often occurs as a consequence of the different resource requirements of females and males, especially during reproduction. The contrasting reproductive roles of the sexes can influence the phenology of growth, plant size and flowering time, with implications for the intensity of competitive interactions within...

Biodiversity across multiple trophic levels is required to maintain multiple ecosystem functions. Yet, it remains unclear how multitrophic diversity and species interactions regulate ecosystem multifunctionality. Here, combining data from nine different trophic groups (including trees, shrubs, herbs, leaf mites, small mammals, bacteria, pathogenic...

Main conclusion CG and CHG methylation levels in the rapid shoot growth stages (ST2–ST4) of woody bamboos were obviously decreased, which might regulate the internode elongation during rapid shoot growth, while CHH methylation was strongly associated with shoot developmental time or age. Abstract DNA methylation plays a critical role in the regula...

Fagus L. is a key component in temperate deciduous broadleaf forests of the Northern Hemisphere. However, its biogeographic history has not been examined under the framework of a fully resolved and reasonably time‐calibrated phylogeny. In this study, we sequenced 28 nuclear single/low‐copy loci (18,555 bp in total) of 11 Fagus species/segregates an...

Full-text available
Three woody bamboo species collected in Hainan, China in 1940 have been described as Dinochloa based on vegetative specimens. However, the identity of these species has long been in doubt, largely because the vegetative phase in species of Dinochloa is morphologically similar to that in species of Melocalamus, a climbing or scrambling bamboo genus...
Article
Plant mitochondrial DNA has been described as evolving rapidly in structure but slowly in sequence. However, many of the noncoding portions of plant mitogenomes are not homologous among species, raising questions about the rate and spectrum of mutations in noncoding regions. Recent studies suggested that the lack of homology in noncoding regions co...

Climate change and geological events have long been known to shape biodiversity, implying that these can likewise be viewed from a biological perspective. To study whether plants can shed light on this, and how they responded to climate change there, we examined Oreocnide, a genus widely distributed in SE Asia. Based on broad geographic sampling wi...

Phylogenetic analyses supported that four traditionally defined families Sterculiaceae, Tiliaceae, Bombacaceae and Malvaceae were subsumed into Malvaceae s.l. and nine subfamilies had been recognized within Malvaceae s.l. However, phylogenetic relationships among the nine subfamilies were not well resolved. Moreover, phylogenetic relationships amon...

Standard plant DNA barcodes based on 2-3 plastid regions, and nrDNA ITS show variable levels of resolution, and fail to discriminate among species in many plant groups. Genome skimming to recover complete plastid genome sequences and nrDNA arrays has been proposed as a solution to address these resolution limitations. However, few studies have empi...
