Genetic Drift in Genetic Algorithm Selection Schemes

, 1999
A method for calculating genetic drift in terms of changing population fitness variance is presented. The method allows for an easy comparison of different selection schemes and exact analytical results are derived for traditional generational selection,

Centromeric tandem repeats expansions in plateau zokor enhance chromosome stability for high-altitude adaptation

Genome Biology
Background Repetitive elements constitute nearly 50% of mammalian genomes; however, their roles in adaptive evolution remain poorly understood. Their identification and assembly, particularly for tandem repeats, are technically challenging, leading to ...

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

FEBS 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 ...

Statistical Genetic Approaches to Investigate Genotype-by-Environment Interaction: Review and Novel Extension of Models [PDF]

Statistical genetic models of genotype-by-environment (G×E) interaction can be divided into two general classes, one on G×E interaction in response to dichotomous environments (e.g., sex, disease-affection status, or presence/absence of an exposure) and ...

Norepinephrine-mediated arousal fluctuations drive inverted U-shaped functional connectivity dynamics

Nature Communications
Arousal states dynamically shape brain function and behavioral performance, as posited by the Yerkes-Dodson law. Yet, functional network substrates underlying this inverted U-shaped pattern remain unknown.

Hide-in-Bird Pond: A new pathway to synergize biodiversity conservation and sustainable development in China

Avian Research
Reconciling biodiversity conservation with economic advancement represents a defining challenge of the Anthropocene epoch. Although ecotourism is widely promoted as a strategy capable of delivering both environmental and developmental benefits, empirical

Phosphoinositides and inositol phosphates as molecular glues

FEBS Letters, EarlyView.
Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Comprehensive evaluation and guidance of structural variation detection tools in chicken whole genome sequence data

BMC Genomics
Background Structural variations (SVs) are widespread across genome and have a great impact on evolution, disease, and phenotypic diversity. Despite the development of numerous bioinformatic tools, commonly referred to as SV callers, tailored for ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.
