Diptera and Drosophila Karyotype Databases: A Useful Dataset to Guide Evolutionary and Genomic Studies

open access: yesFrontiers in Ecology and Evolution, 2022
Karyotypes and chromosome data have been widely used in many subfields of biology over the last century. Unfortunately, this data is largely scattered among hundreds of articles, books, and theses, many of which are only available behind paywalls.

Karyotype analysis of some Onobrychis (sainfoin) species in Turkey [PDF]

open access: yesArchives of Biological Sciences, 2012
In this study, karyotype analysis of the species of Onobrychis sp. was undertaken using the squash method. The results showed that the chromosome number of Onobrychis tournefortii (Willd.) Desv., O. gracilis Besser, O. hypargyrea Boiss. is 2n = 14 and

Chromosome number, genome size and heterochromatin evolution in diploid species of Ipomoea and related genera (Convolvulaceae: Convolvuloideae) [PDF]

open access: yesActa Botânica Brasílica, 2023
Convolvuloideae is a group of plants formed by genera with n = 15 and high stability of chromosome numbers. Despite being stable, polyploidy is the main mechanism of karyotype evolution for the group and seems to be related to speciation events.

Genome Size and Karyotype Studies in Five Species of Lantana (Verbenaceae)

open access: yesHortScience, 2021
Lantana species are an important component of the U.S. environmental horticulture industry. The most commonly produced and used species are L. camara and, on a smaller scale, L. montevidensis. Both were introduced to the United States from Central and/or

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 ...
