Comparative Analysis of Tandem Repeats from Hundreds of Species Reveals Unique Insights into Centromere Evolution [PDF]
, 2012 Centromeres are essential for chromosome segregation, yet their DNA sequences evolve rapidly. In most animals and plants that have been studied, centromeres contain megabase-scale arrays of tandem repeats.

Chromosomal mapping reveals a dynamic organization of the histone genes in aphids (Hemiptera: Aphididae) [PDF]
, 2013 Despite their involvement in different processes, histone genes have been analysed in few insects. In order to improve the knowledge about this important gene family, genes coding for histones have been analysed in the aphid Acyrthosiphon pisum showing ...

Coordinating cohesion, co-orientation, and congression during meiosis: lessons from holocentric chromosomes [PDF]
Genes & Development, 2010 Organisms that reproduce sexually must reduce their chromosome number by half during meiosis to generate haploid gametes. To achieve this reduction in ploidy, organisms must devise strategies to couple sister chromatids so that they stay together during the first meiotic division (when homologous chromosomes separate) and then segregate away from one ...

Functional consequences of chromosome holocentricity
, 2016 Holozentrische Chromosomen treten in einer Reihe von unabhängigen Abstammungen in unterschiedlichen Eukaryoten auf. Diese bilden Zentromere entlang der Gesamtlänge der Schwesterchromatiden. Durch diese Chromosomenstruktur können Arten mit holozentrischen Chromosomen während der Meiose den für monozentrische Chromosomen-typischen Vorgang des Zwei ...

Two types of highly ordered micro- and macrochromosome arrangement in metaphase plates of butterflies (Lepidoptera) [PDF]
Comparative Cytogenetics, 2019 In karyotype of many organisms, chromosomes form two distinct size groups: macrochromosomes and microchromosomes. During cell divisions, the position of the macro- and microchromosomes is often ordered within metaphase plate. In many reptiles, amphibians,

Cenh3: An Emerging Player in Haploid Induction Technology. [PDF]
, 2016 True-breeding lines are required for the development and production of crop varieties. In a classical breeding approach these lines are obtained through inbreeding, and often 7-9 generations of inbreeding is performed to achieve the desired level of ...

CenH3 distribution reveals extended centromeres in the model beetle Tribolium castaneum.
PLoS Genetics, 2020 Centromeres are chromosomal domains essential for kinetochore assembly and correct chromosome segregation. Inconsistent in their underlying DNA sequences, centromeres are defined epigenetically by the presence of the centromere-specific histone H3 ...

Advanced microscopic approaches to the study of eukaryotic chromosomes [PDF]
, 2006 Since the first discoveries of Schneider and Flemming, several papers have been published on chromosome structure making the understanding of chromatin organization in chromosomes one of the most attractive topics of the current biosciences.
