Published in 2017 at "Molecular phylogenetics and evolution"

DOI: 10.1016/j.ympev.2016.09.023

Abstract: Although it is widely appreciated that gene trees may differ from the overall species tree and from one another due to various evolutionary processes (e.g., incomplete lineage sorting (ILS), horizontal gene transfer, etc.), the extent… read more here.

Published in 2022 at "Bioinformatics"

DOI: 10.1093/bioinformatics/btab875

Abstract: MOTIVATION As genome-wide reconstruction of phylogenetic trees becomes more widespread, limitations of available data are being appreciated more than ever before. One issue is that phylogenomic datasets are riddled with missing data, and gene trees,… read more here.

Published in 2022 at "Bioinformatics"

DOI: 10.1093/bioinformatics/btac265

Abstract: Abstract Motivation Phylogenomics faces a dilemma: on the one hand, most accurate species and gene tree estimation methods are those that co-estimate them; on the other hand, these co-estimation methods do not scale to moderately… read more here.

Published in 2017 at "Bioinformatics"

DOI: 10.1093/bioinformatics/btw778

Abstract: Summary: Gene trees reconstructed from sequence alignments contain poorly supported branches when the phylogenetic signal in the sequences is insufficient to determine them all. When a species tree is available, the signal of gains and… read more here.

Filtration of Gene Trees From 9,000 Exons, Introns, and UCEs Disentangles Conflicting Phylogenomic Relationships in Tree Frogs (Hylidae)

Published in 2023 at "Genome Biology and Evolution"

DOI: 10.1093/gbe/evad070

Abstract: Abstract An emerging challenge in interpreting phylogenomic data sets is that concatenation and multi-species coalescent summary species tree approaches may produce conflicting results. Concatenation is problematic because it can strongly support an incorrect topology when… read more here.

Published in 2020 at "Molecular Biology and Evolution"

DOI: 10.1093/molbev/msaa288

Abstract: Abstract How gene function evolves is a central question of evolutionary biology. It can be investigated by comparing functional genomics results between species and between genes. Most comparative studies of functional genomics have used pairwise… read more here.

Published in 2021 at "Molecular biology and evolution"

DOI: 10.1093/molbev/msab234

Abstract: Possvm (Phylogenetic Ortholog Sorting with Species oVerlap and MCL) is a tool that automates the process of identifying clusters of orthologous genes from precomputed phylogenetic trees and classifying gene families. It identifies orthology relationships between… read more here.

Published in 2023 at "Systematic biology"

DOI: 10.1093/sysbio/syad008

Abstract: Prokaryotic genomes are often considered to be mosaics of genes that do not necessarily share the same evolutionary history due to widespread Horizontal Gene Transfers (HGTs). Consequently, representing evolutionary relationships of prokaryotes as bifurcating trees… read more here.

Published in 2017 at "Molecular Ecology"

DOI: 10.1111/mec.14274

Abstract: Multilocus coalescent methods for inferring species trees or historical demographic parameters typically require the assumption that gene trees for sampled SNPs or DNA sequence loci are conditionally independent given their species tree. In practice, researchers… read more here.

Published in 2020 at "PLoS ONE"

DOI: 10.1371/journal.pone.0232950

Abstract: Almost all standard phylogenetic methods for reconstructing gene trees result in unrooted trees; yet, many of the most useful applications of gene trees require that the gene trees be correctly rooted. As a result, several… read more here.

Published in 2019 at "Diversity"

DOI: 10.3390/d11070108

Abstract: The early radiation of Neoaves has been hypothesized to be an intractable “hard polytomy”. We explore the fundamental properties of insertion/deletion alleles (indels), an under-utilized form of genomic data with the potential to help solve… read more here.
