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.

Cytogenetic Studies in Turkey: Fishes (Vertebrata, Pisces)

open access: yesTurkish Journal of Bioscience and Collections, 2021
In Turkey surrounded by sea on three sides and hundreds of freshwater resources, it was reported that there is a total of 903 species of fish including freshwater and marine species. In the last thirty-five years in Turkish fish cytogenetics, 103 species/

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

Multicolour interphase cytogenetics: 24 chromosome probes, 6 colours, 4 layers [PDF]

open access: yes, 2011
From the late 1980s onwards, the use of DNA probes to visualise sequences on individual chromosomes (fluorescent in-situ hybridisation - FISH) revolutionised the study of cytogenetics.

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 ...

The elusive evidence for chromothripsis. [PDF]

open access: yes, 2014
The chromothripsis hypothesis suggests an extraordinary one-step catastrophic genomic event allowing a chromosome to 'shatter into many pieces' and reassemble into a functioning chromosome.

The Chromosome Number of Man [PDF]

open access: yesHereditas, 1956
Desde su aparición en 1944 la Estación Experimental de Aula Dei (EEAD) contempló objetivos de investigación básicos y aplicados, adecuando sus líneas de trabajo a las necesidades de investigación de cada momento. Gracias a una acertada política de reclutamiento de talentos, desde muy temprano se consagró como uno de los centros nacionales de referencia

First Cytogenetic Study Through Conventional Staining of The Ant Genus Blepharidatta Wheeler, 1915 (Hymenoptera: Formicidae: Attini)

open access: yesSociobiology, 2022
Blepharidatta is a rare Neotropical ant genus in the Attini tribe of the subfamily Myrmicinae. It has only four valid species and among them Blepharidatta delabiei was recently described and there is little knowledge on its biology.

Positional and functional mapping of a neuroblastoma differentiation gene on chromosome 11 [PDF]

open access: yes, 2005
Background: Loss of chromosome 11q defines a subset of high-stage aggressive neuroblastomas. Deletions are typically large and mapping efforts have thus far not lead to a well defined consensus region, which hampers the identification of positional ...
