Chiasmata and the kinetochore component Dam1 are crucial for elimination of erroneous chromosome attachments and centromere oscillation at meiosis I [PDF]
Open Biology, 2021 Establishment of proper chromosome attachments to the spindle requires elimination of erroneous attachments, but the mechanism of this process is not fully understood.

Location and Identification on Chromosome 3B of Bread Wheat of Genes Affecting Chiasma Number
Plants, 2022 Understanding meiotic crossover (CO) variation in crops like bread wheat (Triticum aestivum L.) is necessary as COs are essential to create new, original and powerful combinations of genes for traits of agronomical interest.

Assessing the Heat Tolerance of Meiosis in Spanish Landraces of Tetraploid Wheat Triticum turgidum
Plants, 2022 Heat stress alters the number and distribution of meiotic crossovers in wild and cultivated plant species. Hence, global warming may have a negative impact on meiosis, fertility, and crop productions.

GENETIC INTERPRETATION OF CHIASMATA IN DELPHINIUM [PDF]
Genetics, 1963 Asymmetry of the karyotype combined with x-ray induced interchange heterozygosity has been made use of in Delphinium to study the relationship between chiasmata and crossing-over. The tranalocation muitiples in two heterozygous plants were analyzed for chiasma formation in the interstitial segments, and for equational and reductional separation of the ...

PLoS ONE, 2022 Meiotic DNA double-strand breaks produce reciprocally exchanged DNA strands, which mature into chiasmata that hold homologous chromosomes together as bivalents. These bivalents are subsequently separated in the first meiotic division. In a mutant lacking

Asynapsis and meiotic restitution in tomato male meiosis induced by heat stress
Frontiers in Plant Science, 2023 Susceptibility of the reproductive system to temperature fluctuations is a recurrent problem for crop production under a changing climate. The damage is complex as multiple processes in male and female gamete formation are affected, but in general ...

European Journal of Entomology, 2015 Robertsonian fusions account for many of the changes in the evolution of the orthopteran karyotype; in their origin, a centric fusion is involved between two acro-telocentric chromosomes, forming a single bi-armed chromosome.

European Journal of Entomology, 2005 The grasshopper Dichroplus pratensis Bruner is polymorphic and polytypic for a complex Robertsonian system. In this species, centric fusions induce changes in number and position of chiasmata, and thus potentially affect intrachromosomal genetic ...
