Variability in the amount of homoeologous pairing among F1 hybrids. [PDF]

AoB Plants, 2016
Abstract Genes involved in the exclusive pairing of homologous chromosomes have been described in several polyploid species but little is known about the activity of these genes in diploids (which have only one dose of each homoeologous genome).

Marker‐assisted introgression and characterization of the ph1b mutant in modern US and Australian wheats [PDF]

The Plant Genome
The ph1b mutant, a large deletion (∼60 Mb) involving Ph1 (pairing homoeologous 1) on chromosome 5B, was incorporated into five major classes of US wheats, including soft white winter wheat, soft red winter wheat, hard red spring wheat, hard white spring ...

Homoeolog Inference Methods Requiring Bidirectional Best Hits or Synteny Miss Many Pairs [PDF]

Genome Biology and Evolution, 2021
Abstract Homoeologs are pairs of genes or chromosomes in the same species that originated by speciation and were brought back together in the same genome by allopolyploidization. Bioinformatic methods for accurate homoeology inference are crucial for studying the evolutionary consequences of polyploidization, and homoeology is typically ...

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

Crop 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.

Identification of 5P Chromosomes in Wheat-Agropyron cristatum Addition Line and Analysis of Its Effect on Homologous Pairing of Wheat Chromosomes

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.

Wild and Cultivated Homoeologous Barley Chromosomes Can Associate and Recombine in Wheat in the Absence of the Ph1 Locus

Agronomy, 2021
Bread wheat is an allohexaploid that behaves as a diploid during meiosis, the cell division process to produce the gametes occurring in organisms with sexual reproduction.

Cytological diploidization of paleopolyploid genus Zea: Divergence between homoeologous chromosomes or activity of pairing regulator genes? [PDF]

PLoS ONE, 2018
Cytological diploidization process is different in autopolyploid and allopolyploid species. Colchicine applied at the onset of meiosis suppresses the effect of pairing regulator genes resulting multivalents formation in bivalent-forming species ...

Transfer of the ph1b Deletion Chromosome 5B From Chinese Spring Wheat Into a Winter Wheat Line and Induction of Chromosome Rearrangements in Wheat-Aegilops biuncialis Hybrids

Frontiers in Plant Science, 2022
Effective utilization of genetic diversity in wild relatives to improve wheat requires recombination between wheat and alien chromosomes. However, this is suppressed by the Pairing homoeologous gene, Ph1, on the long arm of wheat chromosome 5B.

Homoeologous Recombination: A Novel and Efficient System for Broadening the Genetic Variability in Wheat

Agronomy, 2020
Gene transfer from wild wheat relatives to bread wheat is restricted to homologous recombination. The presence of the Pairing homoeologous 1 (Ph1) gene in the long arm of wheat chromosome 5B allows only homologous chromosomes to pair and recombine ...

A separation-of-function ZIP4 wheat mutant allows crossover between related chromosomes and is meiotically stable

Scientific Reports, 2021
Many species, including most flowering plants, are polyploid, possessing multiple genomes. During polyploidisation, fertility is preserved via the evolution of mechanisms to control the behaviour of these multiple genomes during meiosis.
