Improved haplotype resolution of highly duplicated MHC genes in a long-read genome assembly using MiSeq amplicons [PDF]

open access: yesPeerJ, 2023
Long-read sequencing offers a great improvement in the assembly of complex genomic regions, such as the major histocompatibility complex (MHC) region, which can contain both tandemly duplicated MHC genes (paralogs) and high repeat content.

The metabolic network of the last bacterial common ancestor

open access: yesCommunications Biology, 2021
Joana C. Xavier, Rebecca E. Gerhards and colleagues reconstruct the habitat and lifestyle of the last bacterial common ancestor (LBCA) through the construction of the metabolic network and gene tree analysis of 146 LCBA protein families.

An Update of Orthopoxvirus Molecular Evolution

open access: yesViruses, 2022
Although variola virus (VARV) has been eradicated through widespread vaccination, other orthopoxviruses pathogenic for humans circulate in nature. Recently, new orthopoxviruses, including some able to infect humans, have been found and their complete ...

Genomic sequence capture of Plasmodium relictum in experimentally infected birds

open access: yesParasites & Vectors, 2022
Background Sequencing parasite genomes in the presence of host DNA is challenging. Sequence capture can overcome this problem by using RNA probes that hybridize with the parasite DNA and then are removed from solution, thus isolating the parasite DNA for

The molecular evolution of spermatogenesis across mammals

open access: yesbioRxiv, 2021
The testis produces gametes through spermatogenesis and evolves rapidly at both the morphological and molecular level in mammals^ 1 – 6 , probably owing to the evolutionary pressure on males to be reproductively successful^ 7 .

Genomics and transcriptomics of epizoic Seisonidea (Rotifera, syn. Syndermata) reveal strain formation and gradual gene loss with growing ties to the host

open access: yesBMC Genomics, 2021
Background Seisonidea (also Seisonacea or Seisonidae) is a group of small animals living on marine crustaceans (Nebalia spec.) with only four species described so far. Its monophyletic origin with mostly free-living wheel animals (Monogononta, Bdelloidea)

Realistic Gene Transfer to Gene Duplication Ratios Identify Different Roots in the Bacterial Phylogeny Using a Tree Reconciliation Method

open access: yesLife, 2022
The rooting of phylogenetic trees permits important inferences about ancestral states and the polarity of evolutionary events. Recently, methods that reconcile discordance between gene-trees and species-trees—tree reconciliation methods—are becoming ...

Conspicuousness, phylogenetic structure, and origins of Müllerian mimicry in 4000 lycid beetles from all zoogeographic regions

open access: yesScientific Reports, 2021
Biologists have reported on the chemical defences and the phenetic similarity of net-winged beetles (Coleoptera: Lycidae) and their co-mimics. Nevertheless, our knowledge has remained fragmental, and the evolution of mimetic patterns has not been studied
