Identification of 5P Chromosomes in Wheat-Agropyron cristatum Addition Line and Analysis of Its Effect on Homologous Pairing of Wheat Chromosomes [PDF]
Frontiers in Plant Science, 2022 As an important wheat wild relative, the P genome of Agropyron cristatum (L.) Gaertn. (2n = 4x = 28) is very valuable for wheat improvement. A complete set of wheat-A.

Homologous pairing activities of two rice RAD51 proteins, RAD51A1 and RAD51A2. [PDF]
PLoS ONE, 2013 In higher eukaryotes, RAD51 functions as an essential protein in homologous recombination and recombinational repair of DNA double strand breaks. During these processes, RAD51 catalyzes homologous pairing between single-stranded DNA and double-stranded ...

Role of chromosome ends in meiotic stability, recombination and wheat evolution in the context of breeding [PDF]
BMC Plant BiologyWheat is one of the most important crops worldwide, and understanding its genome organisation is crucial for geneticists and breeders. In this study, we examined the dynamic roles of telomeric and subtelomeric regions in wheat, focusing on their ...

RAD51 D-loop structures reveal the mechanism of eukaryotic RAD51-mediated strand exchange [PDF]
Nature CommunicationsStrand exchange is a key step in homologous recombination, enabling template-based repair of DNA double-strand breaks. Eukaryotic RAD51 forms an ATP-dependent helical presynaptic filament on single-stranded DNA (ssDNA), which then searches for homologous

Differing requirements for RAD51 and DMC1 in meiotic pairing of centromeres and chromosome arms in Arabidopsis thaliana. [PDF]
PLoS Genetics, 2012 During meiosis homologous chromosomes pair, recombine, and synapse, thus ensuring accurate chromosome segregation and the halving of ploidy necessary for gametogenesis.

Meiotic chromosome pairing is promoted by telomere-led chromosome movements independent of bouquet formation. [PDF]
PLoS Genetics, 2012 Chromosome pairing in meiotic prophase is a prerequisite for the high fidelity of chromosome segregation that haploidizes the genome prior to gamete formation. In the budding yeast Saccharomyces cerevisiae, as in most multicellular eukaryotes, homologous

Determinants of Chromosome Architecture: Insulator Pairing in cis and in trans. [PDF]
PLoS Genetics, 2016 The chromosomes of multicellular animals are organized into a series of topologically independent looped domains. This domain organization is critical for the proper utilization and propagation of the genetic information encoded by the chromosome.

A ZIP1 separation-of-function allele reveals that centromere pairing drives meiotic segregation of achiasmate chromosomes in budding yeast. [PDF]
PLoS Genetics, 2018 In meiosis I, homologous chromosomes segregate away from each other-the first of two rounds of chromosome segregation that allow the formation of haploid gametes.
