Evolutionary insights into 3D genome organization and epigenetic landscape of Vigna mungo

Introduction The non-random packaging of chromatin within the nucleus is a universal feature of eukaryotic genomes. The three-dimensional (3D) spatial organization of chromatin could be partitioned at different levels based on the interaction frequency between two given loci in the genome. Advances in sequencing technologies have led to the identification…

epialleleR: an R/Bioconductor package for sensitive allele-specific methylation analysis in NGS data | GigaScience

Abstract Low-level mosaic epimutations within the BRCA1 gene promoter occur in 5–8% of healthy individuals and are associated with a significantly elevated risk of breast and ovarian cancer. Similar events may also affect other tumor suppressor genes, potentially being a significant contributor to cancer burden. While this opens a new…

INTRODUCTION Charles R. Darwin documented inbreeding depression as growth disadvantages from self-fertilization compared to outcrossing in many plants (1). Prevailing hypotheses suggest that inbreeding depression results from the exposure of deleterious recessive alleles and/or loss of overdominant alleles due to increased homozygosity (2, 3) or reduced recombination frequency in some…
