Different modes of variation for each BG lineage suggest different functions [PDF]

open access: yesOpen Biology, 2016
Mammalian butyrophilins have various important functions, one for lipid binding but others as ligands for co-inhibition of αβ T cells or for stimulation of γδ T cells in the immune system.

The genomic landscape of meiotic crossovers and gene conversions in Arabidopsis thaliana

open access: yeseLife, 2013
Knowledge of the exact distribution of meiotic crossovers (COs) and gene conversions (GCs) is essential for understanding many aspects of population genetics and evolution, from haplotype structure and long-distance genetic linkage to the generation of ...

The Roles of Gene Duplication, Gene Conversion and Positive Selection in Rodent \u3ci\u3eEsp\u3c/i\u3e and \u3ci\u3eMup\u3c/i\u3e Pheromone Gene Families with Comparison to the \u3ci\u3eAbp\u3c/i\u3e Family [PDF]

open access: yes, 2012
Three proteinaceous pheromone families, the androgen-binding proteins (ABPs), the exocrine-gland secreting peptides (ESPs) and the major urinary proteins (MUPs) are encoded by large gene families in the genomes of Mus musculus and Rattus norvegicus.

Revealing mammalian evolutionary relationships by comparative analysis of gene clusters [PDF]

open access: yes, 2012
Many software tools for comparative analysis of genomic sequence data have been released in recent decades. Despite this, it remains challenging to determine evolutionary relationships in gene clusters due to their complex histories involving ...

Chromosome End Repair and Genome Stability in Plasmodium falciparum

open access: yesmBio, 2017
The human malaria parasite Plasmodium falciparum replicates within circulating red blood cells, where it is subjected to conditions that frequently cause DNA damage. The repair of DNA double-stranded breaks (DSBs) is thought to rely almost exclusively on

V(D)J Rearrangement Is Dispensable for Producing CDR-H3 Sequence Diversity in a Gene Converting Species

open access: yesFrontiers in Immunology, 2018
An important characteristic of chickens is that the antibody repertoire is based on a single framework, with diversity found mainly in the CDRs of the light and heavy chain variable regions.

Illegitimate Recombination Between Homeologous Genes in Wheat Genome

open access: yesFrontiers in Plant Science, 2020
Polyploidies produce a large number of duplicated regions and genes in genomes, which have a long-term impact and stimulate genetic innovation. The high similarity between homeologous chromosomes, forming different subgenomes, or homologous regions after

Sequence of the mouse Q4 class I gene and characterization of the gene product [PDF]

open access: yes, 1988
The Q4 class I gene has been shown to participate in gene conversion events within the mouse major histocompatibility complex. Its complete genomic nucleotide sequence has been determined.

Gene Duplication and Ectopic Gene Conversion in Drosophila [PDF]

open access: yesGenes, 2011
The evolutionary impact of gene duplication events has been a theme of Drosophila genetics dating back to the Morgan School. While considerable attention has been placed on the genetic novelties that duplicates are capable of introducing, and the role that positive selection plays in their early stages of duplicate evolution, much less attention has ...

Analysis of the recombination landscape of hexaploid bread wheat reveals genes controlling recombination and gene conversion frequency [PDF]

open access: yes, 2019
Background: Sequence exchange between homologous chromosomes through crossing over and gene conversion is highly conserved among eukaryotes, contributing to genome stability and genetic diversity. A lack of recombination limits breeding efforts in crops;
