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 ...

Beyond Deterministic Fetal Programming: Intrauterine Exposures and the Multifactorial Origins of Adiposity

Obesity Reviews, EarlyView.
ABSTRACT Excess adiposity is not a recently developed problem but has existed since at least the upper Paleolithic, allowing evolutionary selection pressures to adapt the physiology of the pregnant woman and the feto‐placental unit for maternal and fetal protection.

Redundant Glycerol‐3‐Phosphate Acyltransferases Regulate Thermo‐Sensitive Genic Male Sterility in Rice

Plant Biotechnology Journal, EarlyView.
ABSTRACT Thermo‐sensitive genic male sterility (TGMS) lines play a pivotal role in two‐line hybrid rice breeding. However, the availability of elite TGMS germplasm remains limited, and the molecular mechanisms underlying fertility transition of TGMS lines are still poorly understood.
