Genomic introgressions from wild relatives in the wheat genome alter meiotic dynamics in inter-varietal hybrids. [PDF]
SUMMARY The use of wild relatives to introduce original diversity in the genome of bread wheat (Triticum aestivum L.) is an interesting approach to face the challenges of sustainable agriculture and the impact of climate change on wheat production. However, the influence of these wild‐species introgressions on meiosis in inter‐varietal wheat hybrids ...

The Evolution and Origin of Allotetraploid Aegilops geniculata Revealed by the Homoeolog-Resolved Genome Assembly. [PDF]
ABSTRACT Aegilops geniculata Roth is a tetraploid (MgMgUgUg; 2n = 4x = 28) wild relative of wheat and a valuable source of genetic diversity for improving agronomic traits. We present a high‐quality homoeolog‐resolved assembly and annotation of the Ae.

Chromosome Pairing in Polyploid Grasses
Polyploids are species in which three or more sets of chromosomes coexist. Polyploidy frequently occurs in plants and plays a major role in their evolution.

Intra- and intergenomic chromosomal pairing in artificially polyploidized elephant grass and pearl millet hybrids [PDF]
: The objective of this work was to evaluate, by genomic in situ hybridization (GISH), pairing configurations as potential indicators of recombination between chromosomes of different parental genomes, in two interspecific hybrids (elephant grass x pearl

Background. One of the ways to use the genetic potential of bulbous barley, which is characterized by a number of valuable traits, is interspecific hybridization. In crosses of H. vulgare (2x) × H. bulbosum (2x) and H. vulgare (4x) × H.

Cytomolecular identification of individual wheat-wheat chromosome arm associations in wheat-rye hybrids [PDF]
Chromosome pairing in the meiotic metaphase I of wheatrye hybrids has been characterized by sequential genomic and fluorescent in situ hybridization allowing not only the discrimination of wheat and rye chromosomes, but also the identification of the

Wheat-barley hybridization – the last forty years [PDF]
Several useful alien gene transfers have been reported from related species into wheat (Triticum aestivum), but very few publications have dealt with the development of wheat/barley (Hordeum vulgare) introgression lines. An overview is given here of

Wheat mutants permitting homoeologous meiotic chromosome pairing
SUMMARYPlants of Triticum aestivum (2n = 6x = 42) ditelocentric 5BL were treated with EMS in order to produce mutations in the 5B system by which meiotic pairing between homoeologous chromosomes is normally prevented. To check for the occurrence of mutation T.

Cryptic homoeology analysis in species and hybrids of genus Zea
Cryptic intergenomic pairing of genus Zea was induced by the use of a diluted colchicine solution in order to elucidate the phylogenetic relations and differentiation of the homoeologous genomes. Results indicate that in species and hybrids with 2n = 20,
