Recombination suppression in plant adaptation and speciation

New Phytologist, Volume 250, Issue 4, Page 2061-2077, May 2026.
Summary Recombination suppression is increasingly recognized as an important facilitator of genomic divergence and speciation, especially under ongoing gene flow. In plants, however, the broader evolutionary consequences and the mechanisms by which recombination suppression arises and spreads are still incompletely understood, reflecting the inherent ...

A Review of the Effects of Maternal and Paternal Obesity on Neurodevelopmental Disorders and Related Neurobiology in Rodent and Human Offspring

Obesity Reviews, Volume 27, Issue 5, May 2026.
ABSTRACT Obesity is one of the most prevalent health problems worldwide, and global obesity rates continue to rise. Consequently, rates of obesity in expecting mothers and fathers have also increased. The Developmental Origins of Health and Disease (DOHaD) hypothesis postulates that early‐life exposure to adverse environmental conditions contributes to

The Role of Histone Modifications in Plant Priming and Their Analysis by Chromatin Immunoprecipitation

Physiologia Plantarum, Volume 178, Issue 3, May/June 2026.
ABSTRACT Plants are frequently exposed to adverse conditions. Priming, also known as acclimation or hardening, induces stress memory and prepares plants for future challenges by activating defense and protective mechanisms. For this reason, priming is an effective means to maintain plant yield in the face of climate change. Memory behind the priming is

Navigating heterochromatin

, 2018
The condensed structure of heterochromatin differs significantly from euchromatin and DNA bound in heterochromatin is generally not transcriptionally active. Transcriptional silencing allows the control of gene expression and affords a novel mechanism of defense against genomic parasites.
