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 ...

Sycp2 is essential for synaptonemal complex assembly, early meiotic recombination and homologous pairing in zebrafish spermatocytes. [PDF]
PLoS Genet, 2020 Meiotic recombination is essential for faithful segregation of homologous chromosomes during gametogenesis. The progression of recombination is associated with dynamic changes in meiotic chromatin structures.

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.

Chromatin architecture may dictate the target site for DMC1, but not for RAD51, during homologous pairing. [PDF]
Sci Rep, 2016 In eukaryotes, genomic DNA is compacted as chromatin, in which histones and DNA form the nucleosome as the basic unit. DMC1 and RAD51 are essential eukaryotic recombinases that mediate homologous chromosome pairing during homologous recombination ...

Homologous Pairing between Long DNA Double Helices [PDF]
Physical Review Letters, 2016 Molecular recognition between two double stranded (ds) DNA with homologous sequences may not seem compatible with the B-DNA structure because the sequence information is hidden when it is used for joining the two strands.

Ontogenes and the Paradox of Homologous Pairing
Advances in Bioscience and Biotechnology (Print), 2021 The mutations in ontogenes have been shown to drastically increase the nondisjunction of X chromosomes in the D. melanogaster meiosis. This means that ontogenes are involved in the process that brings the homologs together although both the genes and ...

New Phytologist, 2020 Homologous recombination (HR) is carefully orchestrated to maintain genome integrity. RAD51D has been previously shown to be essential for double-strand break (DSB) repair in mammalian somatic cells.

New Phytologist, 2019 Meiotic recombination is closely linked with homologous pairing and synapsis. Previous studies have shown that HOMOLOGOUS PAIRING PROTEIN2 (HOP2), plays an essential role in homologous pairing and synapsis.

Nature Communications, 2019 During meiosis, pairing of homologous chromosomes is critical for sexual reproduction. Here the authors reveal in S. pombe the role of lncRNA–protein complexes during the pairing of homologues chromosomes that assemble at specific chromosomal loci to ...

Chromosomally-retained RNA mediates homologous pairing. [PDF]
Nucleus, 2012 Pairing and recombination of homologous chromosomes are essential for ensuring correct segregation of chromosomes in meiosis. In S. pombe, chromosomes are first bundled at the telomeres (forming a telomere bouquet) and then aligned by oscillatory ...
