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

A deep dive into the ancestral chromosome number and genome size of flowering plants.
New Phytologist, 2020 Chromosome number and genome variation in flowering plants has stimulated a blossoming number of speculations about the ancestral chromosome number of angiosperms, but estimates so far remain equivocal.

Chromosome number, sex determination, and meiotic chromosome behavior in the praying mantid Hierodula membranacea. [PDF]
PLoS ONE, 2022 Praying mantids are important models for studying a wide range of chromosome behaviors, yet few species of mantids have been characterized chromosomally.

Chromosome number evolution in skippers (Lepidoptera, Hesperiidae)
Comparative 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 ...

Increased maize chromosome number by engineered chromosome fission. [PDF]
Sci AdvActivation of synthetic centromeres on chromosome 4 in maize leads to its breakage and formation of trisomic fragments called neochromosomes. A limitation of neochromosomes is their low and unpredictable transmission rates due to trisomy. Here we report that selecting for dicentric recombinants through male crosses uncovers stabilized chromosome 4 ...

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

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

chromploid: An R package for chromosome number evolution across the plant tree of life. [PDF]
Appl Plant Sci, 2018 Premise of the Study Polyploidy has profound evolutionary consequences for land plants. Despite the availability of large phylogenetic and chromosomal data sets, estimating the rates of polyploidy and chromosomal evolution across the tree of life remains
