Uprooted Phylogenetic Networks [PDF]

open access: yesBulletin of Mathematical Biology, 2017
The need for structures capable of accommodating complex evolutionary signals such as those found in, for example, wheat has fueled research into phylogenetic networks. Such structures generalize the standard model of a phylogenetic tree by also allowing for cycles and have been introduced in rooted and unrooted form.

MET and NF2 alterations confer primary and early resistance to first‐line alectinib treatment in ALK‐positive non‐small‐cell lung cancer

open access: yesMolecular Oncology, EarlyView.
Alectinib resistance in ALK+ NSCLC depends on treatment sequence and EML4‐ALK variants. Variant 1 exhibited off‐target resistance after first‐line treatment, while variant 3 and later lines favored on‐target mutations. Early resistance involved off‐target alterations, like MET and NF2, while on‐target mutations emerged with prolonged therapy.

Phylogenetic Insights on Patterns of HIV-1 Spread and the Design of Epidemic Control Measures

open access: yesViruses, 2022
Phylogenetics provides a unique structural framework to track the spread of viral diseases, such as HIV-1 (human immunodeficiency virus type 1), the causative agent of AIDS (acquired immunodeficiency syndrome) [...]

Landscape of BRAF transcript variants in human cancer

open access: yesMolecular Oncology, EarlyView.
We investigate the annotation of BRAF variants, focusing on protein‐coding BRAF‐220 (formerly BRAF‐reference) and BRAF‐204 (BRAF‐X1). The IsoWorm pipeline allows us to quantify these variants in human cancer, starting from RNA‐sequencing data. BRAF‐204 is more abundant than BRAF‐220 and impacts patient survival.

Positive selection and relaxed purifying selection contribute to rapid evolution of sex-biased genes in green seaweed Ulva

open access: yesBMC Ecology and Evolution
Background The evolution of differences in gamete size and number between sexes is a cornerstone of sexual selection theories. The green macroalga Ulva, with incipient anisogamy and parthenogenetic gametes, provides a unique system to investigate ...

The dawn of relaxed phylogenetics.

open access: yesPLoS Biology, 2023
Tracing the history of evolution across time is a primary goal of evolutionary biology. The 2006 publication of a landmark study on relaxed phylogenetics in PLOS Biology enabled biologists to shed light on evolution's tempo and shaped the future of ...

Molecular Phylogenetics and Mitochondrial Evolution

open access: yesLife, 2021
The myth of a “typical” mitochondrial genome (mtDNA) is a rock-hard belief in the field of genetics, at least for the animal kingdom [...]

Phylogenetics of Allopolyploids [PDF]

open access: yesAnnual Review of Ecology, Evolution, and Systematics, 2017
We give an overview of recently developed methods to reconstruct phylog-enies of taxa that include allopolyploids that have originated in relatively recent times—in other words, taxa for which at least some of the parental lineages of lower ploidy levels are not extinct and for which ploidy information is clearly shown by variation in chromosome counts.

Comparative study of adenosine 3′‐pyrophosphokinase domains of MuF polymorphic toxins

open access: yesFEBS Open Bio, EarlyView.
With the ultimate goal of understanding the association of toxin‐immunity modules to temperate phages, we characterized toxins from three prophages and examined cross‐protection from immunity proteins. The toxins exhibit adenosine 3′‐pyrophosphokinase activity and are toxic in Escherichia coli.

Transitional areas of vegetation as biodiversity hotspots evidenced by multifaceted biodiversity analysis of a dominant group in Chinese evergreen broad-leaved forests

open access: yesEcological Indicators, 2023
Species in transitional areas often display adaptive responses to climate change and such areas may be crucial for long-term biodiversity conservation.
