Interspecific hybridization causes long‐term phylogenetic discordance between nuclear and mitochondrial genomes in freshwater fishes [PDF]

Molecular Ecology, 2017
AbstractClassification, phylogeography and the testing of evolutionary hypotheses rely on correct estimation of species phylogeny. Early molecular phylogenies often relied on mtDNAalone, which acts as a single linkage group with one history. Over the last decade, the use of multiple nuclear sequences has often revealed conflict among gene trees.

Dissecting discordance of mitochondrial and nuclear phylogenetic trees in insects

Crop Health
The mitochondrial and nuclear genomes present distinct inheritance and genomic structural characteristics. Although both genomes have been widely used for phylogenetic tree reconstruction, topological discordances between trees inferred from ...

Discordant Phylogenomic Placement of Hydnoraceae and Lactoridaceae Within Piperales Using Data From All Three Genomes

Frontiers in Plant Science, 2021
Phylogenetic relationships within the magnoliid order Piperales have been studied extensively, yet the relationships of the monotypic family Lactoridaceae and the holoparasitic Hydnoraceae to the remainder of the order remain a matter of debate.

Phylogenomics, ecomorphological evolution, and historical biogeography in Deuterocohnia (Bromeliaceae: Pitcairnioideae)

American Journal of Botany, EarlyView.
Abstract Premise Species of Deuterocohnia (17 spp.) show extraordinary variation in elevation (0–3900 m a.s.l.) and growth forms, and many have narrow geographic distributions in the west‐central Andes and the Peru‐Chile coast. Previous research using few plastid and nuclear loci failed to produce well‐resolved or supported phylogenies.

Inferring Species Trees from Incongruent Multi-Copy Gene Trees Using the Robinson-Foulds Distance [PDF]

, 2012
We present a new method for inferring species trees from multi-copy gene trees. Our method is based on a generalization of the Robinson-Foulds (RF) distance to multi-labeled trees (mul-trees), i.e., gene trees in which multiple leaves can have the same ...

Phylogenomics reveals the evolution of floral traits associated with pollinators and pollinator–prey conflict within the carnivorous Pinguicula subgenus Temnoceras

American Journal of Botany, EarlyView.
Abstract Premise The carnivorous plant genus Pinguicula (Lentibulariaceae) exhibits remarkable floral diversity associated with pollination, particularly in the largest subgenus Temnoceras, which spans Mexico and Central America. Despite this diversity, the relationships between species and the evolution of key floral traits remain unresolved. Here, we

Mito-nuclear discordance within Anthozoa, with notes on unique properties of their mitochondrial genomes

Scientific Reports, 2023
Whole mitochondrial genomes are often used in phylogenetic reconstruction. However, discordant patterns in species relationships between mitochondrial and nuclear phylogenies are commonly observed.

Not the Cryptic Species: Diversity of Hipposideros gentilis (Chiroptera: Hipposideridae) in Indochina

Diversity, 2021
We present here the result of phylogenetic analysis for Vietnamese Hipposideros gentilis specimens using 7 nuclear genes and one mitochondrial gene. The complex distribution of divergent mitochondrial DNA lineages contradicts, at least in part, nuclear ...

Early evolutionary history of the seed

Biological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Biogeographic discordance of molecular phylogenetic and phenotypic variation in a continental archipelago radiation of land snails [PDF]

BMC Evolutionary Biology, 2014
In island archipelagos, where islands have experienced repeated periods of fragmentation and connection through cyclic changes in sea level, complex among-island distributions might reflect historical distributional changes or local evolution. We test the relative importance of these mechanisms in an endemic radiation of Rhagada land snails in the ...
