Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

FEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Prioritization based on neutral genetic diversity may fail to conserve important characteristics in cattle breeds [PDF]

, 2011
Conservation of the intraspecific genetic diversity of livestock species requires protocols that assess between-breed genetic variability and also take into account differences among individuals within breeds.

The human gut microbiome across the life course

FEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

The Contribution of Genetic Resources and Diversity to Wheat Productivity: A Case from the Punjab of Pakistan [PDF]

This study makes use of data on wheat production in the Punjab of Pakistan from 1979 to 1985 to 1) examine patterns of varietal diversity in farmers' fields both at the regional and district levels and 2) identify how and in what ways genetic resources ...

New additions to the fungal species of Guyana

Studies in Fungi
DNA barcoding is today a standard method used for species identification, preferably in conjunction with supporting morphological data. Here, we employed DNA barcoding using the highly conserved nuclear ribosomal internal transcribed spacer (ITS) region ...

Septin 9 PB domains coordinate centrosome positioning and microtubule acetylation to control epithelial polarity

FEBS Letters, EarlyView.
Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Enhanced acid fuchsin staining for visualization of foliar nematodes using brightfield and fluorescence microscopy

Journal of Nematology
Foliar nematodes are economically important plant pathogens affecting a wide range of hosts, including food crops, ornamentals, and forest trees. Among these, Litylenchus crenatae (family Anguinidae), the causal agent of beech leaf disease (BLD), poses a

Limited role of aquatic habitat complexity in mitigating the ecological impact of invasive bullfrogs on native amphibians

Global Ecology and Conservation
Spatial overlap in habitat use and structural habitat complexity can shape the ecological impact of biological invasions. Environmental conditions that mitigate these impacts can be exploited in nature-based conservation strategies aimed at damage ...

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...
