Homoeologous chromosome pairing across the eukaryote phylogeny

Molecular Phylogenetics and Evolution, 2017
During the past quarter century, molecular phylogenetic inferences have significantly resolved evolutionary relationships spanning the eukaryotic tree of life. With improved phylogenies in hand, the focus of systematics will continue to expand from estimating species relationships toward examining the evolution of specific, fundamental traits across ...

Regulation of homoeologous pairing in pentaploid wheat hybrids

Genetica, 1982
Comparisons were made of levels of chromosome pairing in pentaploid hybrids between normal and ph1b-and ph2-mutant forms of Triticum aestivum ssp. vulgare cv. Chinese Spring each crossed with Triticum kotschyi and T. turgidum var. dicoccoides. Higher levels of multivalent formation in the ph1b-kotschyi, compared with the ph1b-dicoccoides pentaploid was

Centromeric behaviour in wheat with high and low homoeologous chromosomal pairing

Chromosoma, 1997
Control of homoeologous chromosomal pairing in hexaploid wheat stems from a balance between a number of suppressor and promoter genes. This study used centromeric behaviour as a tool to investigate the mechanism. Fluorescent in situ hybridization employing centromeric and telomeric sequences as probes was applied to pollen mother cells of wheat and ...

Attempts to induce homoeologous pairing between wheat and Agropyron cristatum genomes

Genome, 2006
Agropyron cristatum (2n = 4x = 28, PPPP) possesses potentially valuable traits that could be used in wheat (Triticum aestivum) improvement through interspecific hybridization. Homoeologous pairing between wheat chromosomes and P chromosomes added to wheat in a set of wheat – A. cristatum addition lines was assessed. First, the Ph-suppressing effect of

Effectiveness of ph gene in inducing homoeologous chromosome pairing in agrotricum

Theoretical and Applied Genetics, 1977
We observed pairing, when the ph gene was present, between wheat (Triticum aestivum L. em. Thell.) chromosome 4B, and an Agropyron intermedium (Host) Beauv. chromosome (Ai) carrying a gene resistant to wheat streak mosaic (WSM). In a monosomic addition polyhaploid [2n = 22 = 19' + 5B' (ph) + 4B' + Ai'], we recorded an average of 4.1 bivalents and 0.3 ...
