ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis

Journal of Integrative Plant Biology, EarlyView.
The Arabidopsis H3K27 mono‐methyltransferases ATXR5 and ATXR6 repress crossovers within meiotic heterochromatin, are required for heterochromatin condensation and H3K27me1 establishment, and specifically influence the maintenance of DNA methylation in meiocytes.

Revisiting the life cycle of Margalefidinium polykrikoides Group III

Journal of Phycology, EarlyView.
Abstract Dinoflagellates produce cysts as a strategy to withstand environmental stressors, with nutrient depletion generally considered a key trigger for cyst production. Resting cysts are thick‐walled, typically composed of one to several layers, and characterized by a prolonged dormancy period.

Genetic Susceptibility to Periodontitis

Journal of Periodontal Research, EarlyView.
Aim: The aim of this narrative review was to identify genes carrying risk alleles associated with an increased risk of periodontitis and to place them in a biological context. Methods: The literature was reviewed based on predefined criteria. Results: The identified genes largely fall into functions linking immune response with tissue repair. The genes

The 3D genome of Gigaspora margarita unveils stable chromatin and nucleolar organization and symbiont‐dependent genome dynamics

New Phytologist, EarlyView.
Summary Arbuscular mycorrhizal fungi (AMF) are widespread plant symbionts that enhance nutrient acquisition and influence ecosystem productivity. Previous chromosome‐level assemblies of the model species Rhizophagus irregularis revealed a two‐compartment genome architecture (active A and repressed B chromatin compartments), yet its conservation across ...

Long‐term surveillance reveals hybridization by nuclear reassortment and intercontinental spread as major evolutionary drivers in wheat yellow rust

New Phytologist, EarlyView.
Documented incursions of Puccinia striiformis 2009–2023 based on sequential resampling of MLGs/pathogen races on different continents. Summary Evolutionary forces affecting crop pathogens, including hybridization and long‐distance dispersal (LDD), may have strong implications for food security and sustainable plant disease control at global scales ...

Accessory regions and horizontal gene transfer shape the evolution of clonal Colletotrichum nymphaeae infecting strawberry

New Phytologist, EarlyView.
Genetic diversity of strawberry‐infecting Colletotrichum isolates. Summary Rapid adaptation in fungal plant pathogens is often attributed to sexual recombination, yet many important pathogens are largely clonal. We investigated how genetic and phenotypic diversity arises in the predominantly asexual fungus Colletotrichum nymphaeae, the main cause of ...
