We present the first phylogenomic analysis of relationships among all ten families of Liliales, based on 75 plastid genes from 35 species in 29 genera, and 97 additional plastomes stratified across angiosperm lineages. [] Key Method We used a supermatrix approach to extend our analysis to 58 of 64 genera of Liliales, and calibrated the resulting phylogeny against 17 fossil dates to produce a new timeline for monocot evolution. Liliales diverged from other monocots 124 Mya and began splitting into separate…

Molecular phylogenetics and historical biogeography of the tribe Lilieae (Liliaceae): bi-directional dispersal between biodiversity hotspots in Eurasia.

The study shows that biotic interchanges between the QTP region and Irano-Turanian region and the Mediterranean Basin were bi-directional, suggesting the latter was a secondary centre of diversity.

Monocot plastid phylogenomics, timeline, net rates of species diversification, the power of multi-gene analyses, and a functional model for the origin of monocots.

A new functional model for the evolution of monocots and their diagnostic morphological traits from submersed aquatic ancestors is outlined, supported by convergent evolution of many of these traits in aquatic Hydatellaceae (Nymphaeales).

Phylogeny, Age, and Evolution of Tribe Lilieae (Liliaceae) Based on Whole Plastid Genomes

The reconstruction of the ancestral area implies that Lilieae may have originated from the Qinghai-Tibet Plateau: the Himalayas and Hengduan Mountains and uplifting of the QTP likely promoted divergence within the tribe, contributing to a better understanding of the evolutionary history of lilies.

Molecular phylogeny of Megasternini terrestrial water scavenger beetles (Hydrophilidae) reveals repeated continental interchange during Paleocene‐Eocene thermal maximum

The historical biogeography analysis reveals a series of parallel intercontinental dispersal events, including the colonization of South America by Australian members of Oosternina ca.

Historical Biogeography of Melanthiaceae: A Case of Out-of-North America Through the Bering Land Bridge

The molecular dating and the ancestral area analyses suggest that Melanthiaceae most likely originated in North America with its crown group dated at 92.1 mya in the late Cretaceous, which adds an example of “out of North America” migration in the biogeographic history of the Northern Hemisphere.

Historical biogeography of the ancient lycophyte genus Selaginella: early adaptation to xeric habitats on Pangea

Selaginella originated on Euramerica around 383 Ma in the Devonian period, while its peak diversification began with the formation of Pangea, and node density analyses revealed that Selaginellaceae has significantly older median and mean node ages than other putative “ancient” families.

Comparative plastome genomics and phylogenetic analyses of Liliaceae

Nine newly sequenced plastomes for nine Liliaceae genera have been combined with previously published plastome data for this family, providing a total of 86 complete plastid genome sequences covering all 15 currently recognized genera for analyses.

Molecular Phylogeny and Dating of Forsythieae (Oleaceae) Provide Insight into the Miocene History of Eurasian Temperate Shrubs

Molecular dating and biogeographic reconstructions suggest an origin of the Forsythieae species in East China in the Miocene, and discordance between two phylogenies in the position of F. ovata is found suggesting that introgression of the chloroplast genome from one species into the nuclear background of another by interspecific hybridization in East Asian Forsythia species.



Age and biogeography of major clades in Liliales.

A robust phylogeny of 40 genera and all seven families of the Liliales based on rbcL sequences was dated, supporting the Campynemataceae as a monophyletic group and aspects of historical biogeography were investigated by dispersal-vicariance analysis.

Gondwanan origin of major monocot groups inferred from dispersal-vicariance analysis

The results indicated that monocot evolution is related to the comparatively late (Eocene) connection (via Antarctica) and break up of South America and Australasia, but not to the much older connections and separations of the other areas.

Familial relationships of the monocot order Liliales based on a molecular phylogenetic analysis using four plastid loci: matK, rbcL, atpB and atpF‐H

Phylogenetic relationships among families of Liliales were better defined here than in a previous molecular analysis, although the placement of Corsiaceae with plastid data remains problematic.

Robust Inference of Monocot Deep Phylogeny Using an Expanded Multigene Plastid Data Set

Despite substantial variation in the overall rate of molecular evolution among lineages, inferred amounts of change among codon-position data partitions are correlated with each other across the monocot tree, consistent with low incongruence between these partitions.


The core Liliales provide compelling examples of both concerted convergence and phylogenetic niche conservatism and advance arguments for the context-specific adaptive value of each of these traits as well as evidence of parallel trends in other groups.

Assembling the Tree of the Monocotyledons: Plastome Sequence Phylogeny and Evolution of Poales1

The results of an initial project by the Monocot AToL (Angiosperm Tree of Life) team on phylogeny and evolution in Poales are presented, using sequence data for 81 plastid genes from 83 species of angiosperms and recovered highly concordant relationships using maximum likelihood (ML) and maximum parsimony (MP).

Leaf fossils of Luzuriaga and a monocot flower with in situ pollen of Liliacidites contortus Mildenh. & Bannister sp. nov. (Alstroemeriaceae) from the Early Miocene.

Luzuriaga was present in Early Miocene New Zealand, indicating a long paleogeographic history for the genus, and L. peterbannisteri strengthens biogeographic connections between South America and Australasia during the Oligocene and earliest Miocene.

Complete plastid genome sequences of Drimys, Liriodendron, and Piper: implications for the phylogenetic relationships of magnoliids

Evolutionary comparisons of three new magnoliid plastid genome sequences confirm that GC content is unevenly distributed across the genome by location, codon position, and functional group, and phylogenetic analyses provide the strongest support so far for the hypothesis that the magnoliids are sister to a large clade that includes both monocots and eudicots.

Analysis of 81 genes from 64 plastid genomes resolves relationships in angiosperms and identifies genome-scale evolutionary patterns

Phylogenetic trees from multiple methods provide strong support for the position of Amborella as the earliest diverging lineage of flowering plants, followed by Nymphaeales and Austrobaileyales, and the plastid genome trees also provide strongSupport for a sister relationship between eudicots and monocots, and this group is sister to a clade that includes Chloranthales and magnoliids.

Identifying the basal angiosperm node in chloroplast genome phylogenies: sampling one's way out of the Felsenstein zone.

Whereas long sequences reduce variance in branch lengths and molecular dating estimates, the impact of improved taxon sampling on the rooting of the angiosperm phylogeny together with the results of parametric bootstrap analyses demonstrate how long-branch attraction might mislead genome-scale phylogenetic analyses.
