Phylogenetic discordance and genic innovation at the emergence of modern cephalochordates

open access: yes
Abstract Cephalochordates (also known as amphioxus or lancelets) are a group of marine invertebrates occupying a critical phylogenetic position as the sister group to the remaining members of the chordate phylum (vertebrates and tunicates). As such, amphioxus have been key to help understanding the origin and evolution of vertebrate genomes,

Cause of gene tree discord? Distinguishing incomplete lineage sorting and lateral gene transfer in phylogenetics

open access: yes, 2017
Despite recent efforts that have produced data sets with hundreds and thousands of gene regions to resolve regions of the tree of life, recalcitrant nodes persist and disagreement among genes as well as disagreement between individual gene trees and species trees are common.

The Influence of Gene Flow on Species Tree Estimation: A Simulation Study [PDF]

open access: yes, 2014
Gene flow among populations or species and incomplete lineage sorting (ILS) are two evolutionary processes responsible for generating gene tree discordance and therefore hindering species tree estimation.

Incomplete lineage sorting and introgression among genera and species of Liliaceae tribe Tulipeae: insights from phylogenomics

open access: yesBMC Biology
Background Phylogenetic research in Tulipa (Liliaceae), a genus of significant economic and horticultural value, has relied on limited nuclear (mostly nuclear ribosomal internal transcribed spacer, nrITS) and plastid DNA sequences, resulting in low ...

Multiple historical processes obscure phylogenetic relationships in a taxonomically difficult group (Lobariaceae, Ascomycota)

open access: yesScientific Reports, 2019
In the age of next-generation sequencing, the number of loci available for phylogenetic analyses has increased by orders of magnitude. But despite this dramatic increase in the amount of data, some phylogenomic studies have revealed rampant gene-tree ...

Discordance between mitochondrial, nuclear, and symbiont genomes in aphid phylogenetics: who is telling the truth?

open access: yesZoological Journal of the Linnean Society
Abstract Aphids (Aphididae) are intensively studied due to their significance as pests and their captivating biological traits. Despite this interest, the evolutionary history of this insect family is poorly understood. Recent phylogenomic analyses have produced conflicting topologies, complicating our understanding of aphid trait ...

Conserved genome structure and phylogenetic insights for the heterogeneous subfamily of Convallarioideae (Asparagaceae) revealed from plastome data

open access: yesBMC Plant Biology
Background Convallarioideae, a subfamily of Asparagaceae, encompasses a wide range of morphologically diverse lineages previously classified under different traditional families and holds significant economic value.

Characterization of genome-wide phylogenetic conflict uncovers evolutionary modes of carnivorous fungi

open access: yesmBio
Mass extinction has often paved the way for rapid evolutionary radiation, resulting in the emergence of diverse taxa within specific lineages. The emergence and diversification of carnivorous nematode-trapping fungi (NTF) in Ascomycota have been linked ...
