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

A surge of late-occurring meiotic double-strand breaks rescues synapsis abnormalities in spermatocytes of mice with hypomorphic expression of SPO11 [PDF]

open access: yes, 2015
Meiosis is the biological process that, after a cycle of DNA replication, halves the cellular chromosome complement, leading to the formation of haploid gametes.

Colchicine-induced autotetraploidy and altered plant cytogenetic and morpho-physiological traits in Catharanthus roseus (L.) G. Don

open access: yesAdvances in Horticultural Science, 2018
Artificially induced polyploidy is often used to alter plant growth pattern and genetic makeup of certain plant species. This experiment was conducted to induce autotetraploidy in Catharanthus roseus (‘Alba’) which contains diploid chromosomes ...

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.

CENH3-GFP: a visual marker for gametophytic and somatic ploidy determination in Arabidopsis thaliana [PDF]

open access: yes, 2016
Background: The in vivo determination of the cell-specific chromosome number provides a valuable tool in several aspects of plant research. However, current techniques to determine the endosystemic ploidy level do not allow non-destructive, cell-specific
