A new subfamily classification of the leguminosae based on a taxonomically comprehensive phylogeny

open access: yes, 2017
The classification of the legume family proposed here addresses the long-known non-monophyly of the traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported monophyletic subfamilies.

Genomic landscape of the global oak phylogeny

open access: yesbioRxiv, 2019
The tree of life is highly reticulate, with the history of population divergence buried amongst phylogenies deriving from introgression and lineage sorting.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Phylogeny numbers

open access: yesDiscrete Applied Mathematics, 1998
For an acyclic digraph \(D=(V,A)\), the phylogeny graph \(P(D)=(V,E)\) has, for vertices \(x\neq y\), an (undirected) edge \(xy\in E\) iff (1) \((x,y)\in A\) or (2) \((y,x)\in A\) or (3) (both) \((x,a),(y,a)\in A\) for some vertex \(a\in V\); it is a supergraph of the competition graph of \(D\) for which only condition (3) is required.

Phylogenies Without Fossils [PDF]

open access: yesEvolution, 1994
Phylogenies that are reconstructed without fossil material often contain approximate dates for lineage splitting. For example, particular nodes on molecular phylogenies may be dated by known geographic events that caused lineages to split, thereby calibrating a molecular clock that is used to date other nodes.

The Ascomycota tree of life: a phylum-wide phylogeny clarifies the origin and evolution of fundamental reproductive and ecological traits [PDF]

open access: yes, 2009
We present a 6-gene, 420-species maximum-likelihood phylogeny of Ascomycota, the largest phylum of Fungi. This analysis is the most taxonomically complete to date with species sampled from all 15 currently circumscribed classes.

The First Genome Survey of the Snail Provanna glabra Inhabiting Deep-Sea Hydrothermal Vents

open access: yesAnimals, 2023
The snail P. glabra is an endemic species in deep-sea chemosynthetic ecosystems of the Northwest Pacific Ocean. To obtain more genetic information on this species and provide the basis for subsequent whole-genome map construction, a genome survey was ...

Fungal evolution: diversity, taxonomy and phylogeny of the Fungi

open access: yesBiological Reviews of The Cambridge Philosophical Society, 2019
The fungal kingdom comprises a hyperdiverse clade of heterotrophic eukaryotes characterized by the presence of a chitinous cell wall, the loss of phagotrophic capabilities and cell organizations that range from completely unicellular monopolar organisms ...

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

2011 German Escherichia coli outbreak: Alignment-free whole-genome phylogeny by feature frequency profiles [PDF]

open access: yes, 2011
Accuracy of SNP-based whole-genome phylogeny reconstruction relies heavily on quality of sequence alignment which is particularly hindered by poorly assembled genomes. Alignment-free methods might provide additional insights. Here, we constructed a whole-
