Time of divergence among D. elongatus populations based on Bayesian coalescent estimation.

open access: yes, 2012
Time of divergence among populations are in million years. Bayesian coalescent estimation of time to most recent common ancestor (TMRCA) with 95% highest posterior density modeled assuming a relaxed molecular clock as implemented in BEAST are shown.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Plastid phylogenomics reveals evolutionary relationships in the mycoheterotrophic orchid genus Dipodium and provides insights into plastid gene degeneration

open access: yesFrontiers in Plant Science
The orchid genus Dipodium R.Br. (Epidendroideae) comprises leafy autotrophic and leafless mycoheterotrophic species, with the latter confined to sect. Dipodium. This study examined plastome degeneration in Dipodium in a phylogenomic and temporal context.

Phase change for the accuracy of the median value in estimating divergence time

open access: yesBMC Bioinformatics, 2013
We prove that for general models of random gene-order evolution of k ≥ 3 genomes, as the number of genes n goes to ∞, the median value approximates k times the divergence time if the number of rearrangements is less than cn/4 for any c

Divergence time estimation between cephalochordates.

open access: yes, 2020
The timetree was generated using the RelTime method. Two calibration points were used: the divergence times between vertebrates and cephalochordates (603.55–697 Ma) and between cyclostomes and gnathostomes (412.75–462.50 Ma) as proposed by Zhang et al ...

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Accounting for Calibration Uncertainty in Phylogenetic Estimation of Evolutionary Divergence Times

open access: yesSystematic Biology, 2009
The estimation of phylogenetic divergence times from sequence data is an important component of many molecular evolutionary studies. There is now a general appreciation that the procedure of divergence dating is considerably more complex than that initially described in the 1960s by Zuckerkandl and Pauling (1962, 1965).

Divergence time estimation of HPV16 complete genome variants.

open access: yes, 2018
A Bayesian MCMC method was used to calculate the divergence times of HPV16 complete genome variants from their most recent common ancestors, as described in the methods.
