Molecular Ecology, Volume 33, Issue 24, December 2024.Abstract Large‐scale chromosome rearrangements, such as fissions and fusions, are a common feature of eukaryote evolution. They can have considerable influence on the evolution of populations, yet it remains unclear exactly how rearrangements become established and eventually fix. Rearrangements could fix by genetic drift if they are weakly deleterious

Memorias do Instituto Oswaldo Cruz, 2013 In this study, we used fluorescence in situ hybridisation to determine the chromosomal location of 45S rDNA clusters in 10 species of the tribe Rhodniini (Hemiptera: Reduviidae: Triatominae).

Frontiers in Genetics, 2020 Heterozygotes for major chromosomal rearrangements such as fusions and fissions are expected to display a high level of sterility due to problems during meiosis. However, some species, especially plants and animals with holocentric chromosomes, are known

The condensin complex is required for proper spindle assembly and chromosome segregation in Xenopus egg extracts. [PDF]
, 2003 Chromosome condensation is required for the physical resolution and segregation of sister chromatids during cell division, but the precise role of higher order chromatin structure in mitotic chromosome functions is unclear.

Characterization of Non-LTR Retrotransposable TRAS Elements in the Aphids Acyrthosiphon pisum and Myzus persicae (Aphididae, Hemiptera) [PDF]
, 2013 A non-LTR TRAS retrotransposon (identified as TRASAp1) has been amplified in the pea aphid Acyrthosiphon pisum and its presence has been assessed also in the peach potato aphid Myzus persicae.

Oligo-barcode illuminates holocentric karyotype evolution in Rhynchospora (Cyperaceae)
Frontiers in Plant ScienceHolocentric karyotypes are assumed to rapidly evolve through chromosome fusions and fissions due to the diffuse nature of their centromeres. Here, we took advantage of the recent availability of a chromosome-scale reference genome for Rhynchospora ...

Cell Reports, 2016 The stability of the genome is paramount to organisms. However, diverse eukaryotes carry out programmed DNA elimination in which portions or entire chromsomes are lost in early development or during sex determination.

Evidence of hermaphroditism and sex ratio distortion in the fungal feeding nematode Bursaphelenchus okinawaensis [PDF]
, 2014 Nematodes have many different reproductive strategies along with their divergent life-histories; the ability of hermaphrodite to self- and cross-fertilize is useful for genetic manipulation.

Chromosome and genome size variation in Luzula (Juncaceae), a genus with holocentric chromosomes
, 2012 The present study examines chromosome and genome size evolution in Luzula (woodrush; Juncaceae), a monocot genus with holocentric chromosomes. Detailed karyotypes and genome size estimates were obtained for seven Luzula spp., and these were combined with additional data from the literature to enable a comprehensive cytological analysis of the genus. So
