The promise and challenges of characterizing genome‐wide structural variants: A case study in a critically endangered parrot

open access: yesMolecular Ecology Resources, EarlyView., 2023
Abstract There is growing interest in the role of structural variants (SVs) as drivers of local adaptation and speciation. From a biodiversity genomics perspective, the characterization of genome‐wide SVs provides an exciting opportunity to complement single nucleotide polymorphisms (SNPs). However, little is known about the impacts of SV discovery and

Easy‐to‐use R functions to separate reduced‐representation genomic datasets into sex‐linked and autosomal loci, and conduct sex assignment

open access: yesMolecular Ecology Resources, EarlyView., 2023
Abstract Identifying sex‐linked markers in genomic datasets is important because their presence in supposedly neutral autosomal datasets can result in incorrect estimates of genetic diversity, population structure and parentage. However, detecting sex‐linked loci can be challenging, and available scripts neglect some categories of sex‐linked variation.

A panoramic view of cotton resistance to Verticillium dahliae: From genetic architectures to precision genomic selection

open access: yesiMeta, EarlyView.
This study identified 10 reliable quantitative trait loci (QTLs) governing cotton resistance to V. dahliae in various environments through a genome‐wide association analysis (GWAS) using an upland cotton population. The pyramid of these 10 elite alleles reduced the disease index of cotton to V. dahliae from 70 to 20.

Scaling‐up RADseq methods for large datasets of non‐invasive samples: Lessons for library construction and data preprocessing

open access: yesMolecular Ecology Resources, EarlyView., 2023
Abstract Genetic non‐invasive sampling (gNIS) is a critical tool for population genetics studies, supporting conservation efforts while imposing minimal impacts on wildlife. However, gNIS often presents variable levels of DNA degradation and non‐endogenous contamination, which can incur considerable processing costs. Furthermore, the use of restriction‐

The influence of microbiome‐derived amino acids metabolites in shaping the glioma immunosuppressive microenvironment

open access: yesInterdisciplinary Medicine, EarlyView.
Left: The disruption of the balance between carcinogenic bacteria and probiotics mediated by antibiotics, protein, and glucose intake. Middle: The gut microbiota‐derived amino acids, primarily through tryptophan, tyrosine, arginine, and branched‐chain amino acid pathways, regulate glioma development via mechanisms such as AHR activation, metabolic ...
