Chromosome number evolution in skippers (Lepidoptera, Hesperiidae) [PDF]

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 ...

THE CHROMOSOME NUMBER OF MAIZE [PDF]

open access: bronzeGenetics, 1925
The wide-spread interest in the genetics of maize, coupled with the uncertainty as to the number of chromosomes occurring in this species prompted the investigation which is here reported. From a review of the literature it appears that Kuwada (1911, 1915, 1919) is the only worker who has reported extensive counts of maize chromosomes.

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.

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 ...

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 ...
