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

Frontiers 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.

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

Chromosome movements promoted by the mitochondrial protein SPD-3 are required for homology search during Caenorhabditis elegans meiosis.

PLoS Genetics, 2013
Pairing of homologous chromosomes during early meiosis is essential to prevent the formation of aneuploid gametes. Chromosome pairing includes a step of homology search followed by the stabilization of homolog interactions by the synaptonemal complex (SC)

Chromosome assignment of two cloned DNA probes hybridizing predominantly to human sex chromosomes [PDF]

, 1984
In situ hybridization experiments were carried out with two clones, YACG 35 and 2.8, which had been selected from two genomic libraries strongly enriched for the human Y chromosome.

Errors in chromosome segregation during oogenesis and early embryogenesis [PDF]

, 2010
Errors in chromosome segregation occurring during human oogenesis and early embryogenesis are very common. Meiotic chromosome development during oogenesis is subdivided into three distinct phases.

Competition of Parental Genomes in Plant Hybrids

Frontiers in Plant Science, 2020
Interspecific hybridization represents one of the main mechanisms of plant speciation. Merging of two genomes from different subspecies, species, or even genera is frequently accompanied by whole-genome duplication (WGD).

Cytological and molecular characterization of wheat lines with Thinopyrum intermedium chromosome additions, substitutions and translocations resistant to barley yellow dwarf virus [PDF]

, 1999
Barley yellow dwarf virus (BYDV) is the most serious viral disease affecting wheat and genes for BYDV resistance have not been found in wheat. BYDV-resistant alien addition and alien substitution lines produced from a wheat × Thinopyrum intermedium ...
