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.

Chromosome Pairing in Polyploid Grasses

Frontiers in Plant Science, 2020
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]

Pesquisa Agropecuária Brasileira, 2017
: 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

GISH reveals different levels of meiotic pairing with wheat for individual Aegilops biuncialis chromosomes

Biologia Plantarum, 2010
The Triticum aestivum - Aegilops biuncialis (2n=4x=28; UbUbMbMb) disomic addition lines 2Mb, 3Mb, 7Mb and 3Ub were crossed with the wheat cv.

Homoeologous chromosome pairing at metaphase I of meiosis in Hordeum vulgare L. × H. bulbosum L. triploid hybrids (HvHbHb)

Биотехнология и селекция растений, 2020
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]

, 2013
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

The use of homoeologous pairing in the identification of homoeologous relationships in Triticeae [PDF]

Hereditas, 2008
Homoeologous pairing at metaphase I was analyzed in different wheat-rye combinations to establish the arm homoeology of wheat and rye chromosomes. Chromosome arms being bound at metaphase 1 were identified by means of C-banding. Pairing between chromosome arms of different homoeologous groups revealed the existence of translocations that occurred ...

Biochemical evidence of chromosome homoeology among related plant genera. [PDF]

, 1975
Biochemical markers associated with homoelogous chromosome groups 3 and 7 of Triticum aestivum L. have been investigated in genetic stocks carrying chromosomes or chromosomal segments of the same homoeology groups from Agropyron elongatum and Secale ...

Cryptic homoeology analysis in species and hybrids of genus Zea

Biologia Plantarum, 2013
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,

Introgression of Seedling Plant Resistance to Leaf Rust from Agropyron cristatum into Wheat by Induced Homoeologous Recombination

Agronomy, 2023
Agropyron cristatum (P genome) is a Triticeae species from the wheat tertiary gene pool which has economic importance as forage and also displays traits beneficial to wheat. Resistance to leaf rust was previously mapped to the short arm of chromosome 1P (
