Contribution of crossing over to genetic variance in maize and wheat populations [PDF]

open access: yesThe Plant Genome
Crossing over breaks linkages and leads to a wider array of allele combinations. My objective was to assess the contribution of crossing over to genetic variance (VG) in maize (Zea mays L.) and wheat (Triticum aestivum L.).

A high-resolution crossover landscape in Drosophila santomea reveals rapid and concerted evolution of multiple properties of crossing over control. [PDF]

open access: yesPLoS Genetics
Crossing over is a fundamental process in sexually reproducing species, ensuring proper chromosome segregation during gamete formation and generating new allelic combinations that enhance adaptation. Despite its essential role, genes involved in crossing

Overexpression of NtGSTU10 gene enhances nicotine content in hybrids by promoting the synthesis and transport metabolism of nicotine [PDF]

open access: yesBMC Biotechnology
Background Nicotine exhibits positive heterosis, and through its utilization, new tobacco varieties with ideal nicotine content have been bred. However, the potential mechanism underlying the increased transport and nicotine accumulation capacity in ...

Exo1 protects DNA nicks from ligation to promote crossover formation during meiosis.

open access: yesPLoS Biology, 2023
In most sexually reproducing organisms crossing over between chromosome homologs during meiosis is essential to produce haploid gametes. Most crossovers that form in meiosis in budding yeast result from the biased resolution of double Holliday junction ...

Selection strategies for the development of maize introgression populations. [PDF]

open access: yesPLoS ONE, 2014
Introgression libraries are valuable resources for QTL detection and breeding, but their development is costly and time-consuming. Selection strategies for the development of introgression populations with a limited number of individuals and high ...

Senataxin plays an essential role with DNA damage response proteins in meiotic recombination and gene silencing. [PDF]

open access: yesPLoS Genetics, 2013
Senataxin, mutated in the human genetic disorder ataxia with oculomotor apraxia type 2 (AOA2), plays an important role in maintaining genome integrity by coordination of transcription, DNA replication, and the DNA damage response.

Widespread gene conversion in centromere cores. [PDF]

open access: yesPLoS Biology, 2010
Centromeres are the most dynamic regions of the genome, yet they are typified by little or no crossing over, making it difficult to explain the origin of this diversity.

Meiotic recombination in Arabidopsis is catalysed by DMC1, with RAD51 playing a supporting role. [PDF]

open access: yesPLoS Genetics, 2013
Recombination establishes the chiasmata that physically link pairs of homologous chromosomes in meiosis, ensuring their balanced segregation at the first meiotic division and generating genetic variation.
