The KL system in wheat permits homoeologous crossing over between closely related chromosomes

open access: yesCrop Journal, 2023
The Chinese wheat landrace Kaixianluohanmai (KL) expresses the ph-like phenotype. A major QTL, QPh.sicau-3A (syn. phKL), responsible for this effect has been mapped to chromosome arm 3AL.

Differing requirements for RAD51 and DMC1 in meiotic pairing of centromeres and chromosome arms in Arabidopsis thaliana. [PDF]

open access: yesPLoS Genetics, 2012
During meiosis homologous chromosomes pair, recombine, and synapse, thus ensuring accurate chromosome segregation and the halving of ploidy necessary for gametogenesis.

CHROMOSOME PAIRING IN MAIZE [PDF]

open access: yesGenetics, 1972
ABSTRACT This report summarizes our observations at pachytene on opposite-arms intercrosses between stocks of interchanges that involve chromosomes 1 and 5 in maize.—Pairing does not begin at the centromeres in these intercrosses.—We propose a model which assumes different probability values along each chromosome arm for the initial or ...

Preferential meiotic chromosome pairing among homologous chromosomes with cryptic sequence variation in tetraploid maize.

open access: yesNew Phytologist, 2020
Meiotic chromosome pairing between homoeologous chromosomes was reported in many nascent allopolyploids. Homoeologous pairing is gradually eliminated and replaced by exclusive homologous pairing in well-established allopolyploids, an evolutionary process

MATHEMATICS OF CHROMOSOME PAIRING [PDF]

open access: yesGenetics, 1980
ABSTRACT Analysis of frequencies of chromosome configurations in wheat-related species hybrids is extended to include cases involving homoeologous groups of size six. Further, the expected frequencies of the various configurations emanating from homologous and homoeologous pairing events have been determined for groups consisting of two ...

Chromosome painting reveals asynaptic full alignment of homologs and HIM-8-dependent remodeling of X chromosome territories during Caenorhabditis elegans meiosis. [PDF]

open access: yesPLoS Genetics, 2011
During early meiotic prophase, a nucleus-wide reorganization leads to sorting of chromosomes into homologous pairs and to establishing associations between homologous chromosomes along their entire lengths.

Multiple opposing constraints govern chromosome interactions during meiosis. [PDF]

open access: yesPLoS Genetics, 2013
Homolog pairing and crossing over during meiosis I prophase is required for accurate chromosome segregation to form euploid gametes. The repair of Spo11-induced double-strand breaks (DSB) using a homologous chromosome template is a major driver of ...

The courtship choreography of homologous chromosomes: timing and mechanisms of DSB-independent pairing

open access: yesFrontiers in Cell and Developmental Biology, 2023
Meiosis involves deep changes in the spatial organisation and interactions of chromosomes enabling the two primary functions of this process: increasing genetic diversity and reducing ploidy level.

Somatic pairing of chromosome 19 in renal oncocytoma is associated with deregulated EGLN2-mediated [corrected] oxygen-sensing response. [PDF]

open access: yesPLoS Genetics, 2008
Chromosomal abnormalities, such as structural and numerical abnormalities, are a common occurrence in cancer. The close association of homologous chromosomes during interphase, a phenomenon termed somatic chromosome pairing, has been observed in ...
