Chromosome number evolves at equal rates in holocentric and monocentric clades. [PDF]

open access: yesPLoS Genet, 2020
Despite the fundamental role of centromeres two different types are observed across plants and animals. Monocentric chromosomes possess a single region that function as the centromere while in holocentric chromosomes centromere activity is spread across ...

Chromosome number, sex determination, and meiotic chromosome behavior in the praying mantid Hierodula membranacea. [PDF]

open access: yesPLoS ONE, 2022
Praying mantids are important models for studying a wide range of chromosome behaviors, yet few species of mantids have been characterized chromosomally.

The genome size, chromosome number and the seed adaption to long-distance dispersal of Ipomoea pes-caprae (L.) [PDF]

open access: yesFrontiers in Plant Science, 2023
Ipomoeapes-caprae (L.) (IPC) is a common species in tropical and subtropical coastal areas and one of the world’s most widely distributed plants. It has attracted researchers for its outstanding biological, ecological and medicinal values.

Genome size variation at constant chromosome number is not correlated with repetitive DNA dynamism in Anacyclus (Asteraceae). [PDF]

open access: yesAnn Bot, 2020
BACKGROUND AND AIMS Changes in the amount of repetitive DNA (dispersed and tandem repeats) are considered the main contributors to genome size variation across plant species in the absence of polyploidy. However, the study of repeatome dynamism in groups

Chromosome number evolution in skippers (Lepidoptera, Hesperiidae)

open access: yesComparative Cytogenetics, 2014
Lepidoptera (butterflies and moths), as many other groups of animals and plants, simultaneously represent preservation of ancestral karyotype in the majority of families with a high degree of chromosome number instability in numerous independently ...

Variation in genome size, cell and nucleus volume, chromosome number and rDNA loci among duckweeds. [PDF]

open access: yesSci Rep, 2019
Duckweeds are small, free-floating, largely asexual and highly neotenous organisms. They display the most rapid growth among flowering plants and are of growing interest in aquaculture and genome biology.

Unscrambling phylogenetic effects and ecological determinants of chromosome number in major angiosperm clades. [PDF]

open access: yesSci Rep, 2018
As variations in the chromosome number are recognized to be of evolutionary interest but are also widely debated in the literature, we aimed to quantitatively test for possible relationships among the chromosome number, plant traits, and environmental ...

Sex and Pubertal Differences in the Type 1 Interferon Pathway Associate With Both X Chromosome Number and Serum Sex Hormone Concentration. [PDF]

open access: yesFront Immunol, 2018
Type 1 interferons (IFN) are an antiviral cytokine family, important in juvenile onset systemic lupus erythematosus (jSLE) which is more common in females, around puberty.

Mechanisms of chromosome number evolution in yeast. [PDF]

open access: yesPLoS Genetics, 2011
The whole-genome duplication (WGD) that occurred during yeast evolution changed the basal number of chromosomes from 8 to 16. However, the number of chromosomes in post-WGD species now ranges between 10 and 16, and the number in non-WGD species ...

Evolutionary mechanisms of runaway chromosome number change in Agrodiaetus butterflies. [PDF]

open access: yesSci Rep, 2017
Despite predictions of the classic, hybrid-sterility model of chromosomal speciation, some organisms demonstrate high rate of karyotype evolution. This rate is especially impressive in Agrodiaetus butterflies that rapidly evolved the greatest chromosome ...
