The highly rearranged mitochondrial genomes of the crabs Maja crispata and Maja squinado (Majidae) and gene order evolution in Brachyura [PDF]

open access: yes, 2017
We sequenced the mitochondrial genomes of the spider crabs Maja crispata and Maja squinado (Majidae, Brachyura). Both genomes contain the whole set of 37 genes characteristic of Bilaterian genomes, encoded on both \u3b1- and \u3b2-strands.

Going nuclear: gene family evolution and vertebrate phylogeny reconciled [PDF]

open access: yes, 2002
Gene duplications have been common throughout vertebrate evolution, introducing paralogy and so complicating phylogenctic inference from nuclear genes.

Integrated pipeline for inferring the evolutionary history of a gene family embedded in the species tree: a case study on the STIMATE gene family

open access: yesBMC Bioinformatics, 2017
Background Because phylogenetic inference is an important basis for answering many evolutionary problems, a large number of algorithms have been developed.

Hierarchy and Feedback in the Evolution of the E. coli Transcription Network [PDF]

open access: yes, 2007
The E.coli transcription network has an essentially feedforward structure, with, however, abundant feedback at the level of self-regulations. Here, we investigate how these properties emerged during evolution.

Multiple Optimal Reconciliations Under the Duplication-Loss-Coalescence Model

open access: yesIEEE/ACM Transactions on Computational Biology & Bioinformatics, 2019
Gene trees can differ from species trees due to a variety of biological phenomena, the most prevalent being gene duplication, horizontal gene transfer, gene loss, and coalescence.

Network Models of Phage-Bacteria Coevolution [PDF]

open access: yes, 2006
Bacteria and their bacteriophages are the most abundant, widespread and diverse groups of biological entities on the planet. In an attempt to understand how the interactions between bacteria, virulent phages and temperate phages might affect the ...

Fast and accurate methods for phylogenomic analyses

open access: yesBMC Bioinformatics, 2011
Background Species phylogenies are not estimated directly, but rather through phylogenetic analyses of different gene datasets. However, true gene trees can differ from the true species tree (and hence from one another) due to biological processes such ...

Genomic Expansion of Magnetotactic Bacteria Reveals an Early Common Origin of Magnetotaxis with Lineage-specific Evolution [PDF]

open access: yes, 2018
The origin and evolution of magnetoreception, which in diverse prokaryotes and protozoa is known as magnetotaxis and enables these microorganisms to detect Earth’s magnetic field for orientation and navigation, is not well understood in evolutionary ...

The UlaG protein family defines novel structural and functional motifs grafted on an ancient RNase fold

open access: yesBMC Evolutionary Biology, 2011
Background Bacterial populations are highly successful at colonizing new habitats and adapting to changing environmental conditions, partly due to their capacity to evolve novel virulence and metabolic pathways in response to stress conditions and to ...

Expansive evolution of the TREHALOSE-6-PHOSPHATE PHOSPHATASE gene family in Arabidopsis [PDF]

open access: yes, 2012
Trehalose is a nonreducing sugar used as a reserve carbohydrate and stress protectant in a variety of organisms. While higher plants typically do not accumulate high levels of trehalose, they encode large families of putative trehalose biosynthesis genes.
