Factors determining chromosomal localization of transposable elements in plants
Plant Biology, Volume 27, Issue 6, Page 975-989, October 2025.We review transposon chromosomal niches, and the functional consequences of their specific chromosomal localization in plants. Abstract Transposable elements (TEs) constitute a significant part of plant genomes and shape their genomic landscape. While some TEs are ubiquitously dispersed, other elements specifically occupy discrete genomic loci.

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.

Diverging repeatomes in holoparasitic Hydnoraceae uncover a playground of genome evolution
New Phytologist, Volume 247, Issue 3, Page 1520-1537, August 2025.Summary The transition from an autotrophic to a heterotrophic lifestyle is associated with numerous genomic changes. These often involve large genomic alterations, potentially driven by repetitive DNAs. Despite their recognized role in shaping plant genomes, the contribution of repetitive DNAs to parasitic plant genome evolution remains largely ...

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 ...

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,

The Plant Journal, Volume 122, Issue 2, April 2025.SUMMARY The section Alatae of genus Lemna of the monocotyledonous aquatic duckweed family (Lemnaceae) consists of rather diverse accessions with unknown phylogeny and unclear taxonomic assignment. In contrast to other duckweeds, some Alatae accessions, in addition to mainly vegetative propagation, produce readily flowers and viable seeds.

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 ...

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 ...

LAB-1 Targets PP1 and Restricts Aurora B Kinase upon Entrance into Meiosis to Promote Sister Chromatid Cohesion [PDF]
, 2012 Successful execution of the meiotic program depends on the timely establishment and removal of sister chromatid cohesion. LAB-1 has been proposed to act in the latter by preventing the premature removal of the meiosis-specific cohesin REC-8 at metaphase ...
