Tetraploidisation plays a crucial role in evolution, development, stress adaptation, and disease, but its beneficial or pathological effects in different tissues remain unclear. This study aims to compare physiological and unphysiological t...
Towards identification of a holocentromere marker in the lepidopteran model Spodoptera frugiperda [0.03%]
向识别夜蛾模式生物Spodoptera frugiperda中的整体着丝粒标记方向努力

Some insects have holocentric chromosomes, with multiple kinetochores rather than a single centromere. They also lack the CENP-A and CENP-C proteins, suggesting a kinetochore assembly process different from that of monocentric chromosomes. ...
Genome location, evolution and centromeric contribution of satellite DNAs shared between the two closely related species Drosophila serido and D. antonietae (repleta group, buzzatii cluster) [0.03%]
两种密切相关物种Drosophila serido和D. antonietae（repleta组，buzzatii亚群）中共享的卫星DNA的基因组位置、进化及其着丝粒贡献

Satellite DNAs are highly repetitive, tandemly arranged sequences, typically making up large portions (> 20%) of the eukaryotic genome. Most satDNAs are fast evolving and changes in their abundance and nucleotide composition may be related ...

Therian female mammals compensate for the dosage of X-linked gene expression by inactivating one of the X-chromosomes. X-inactivation is facilitated by the master regulator Xist long non-coding RNA, which coats the inactive-X and facilitate...

Polyploidy is a common feature in eukaryotes with one of paramount consequences leading to better environmental adaptation. Heterochromatin is often located at telomeres and centromeres and contains repetitive DNA sequences. Sainfoin (Onobr...
CCAAT Promoter element regulates transgenerational expression of the MHC class I gene [0.03%]

Centromeres are chromatin structures specialized in sister chromatid cohesion, kinetochore assembly, and microtubule attachment during chromosome segregation. The regional centromere of vertebrates consists of long regions of highly repetit...

Meiosis is the specialized cellular program that underlies gamete formation for sexual reproduction. It is therefore not only interesting but also a fundamentally important subject for investigation. An especially attractive feature of this...

Among the repetitive elements, satellite DNA (SatDNA) emerges as extensive arrays of highly similar tandemly repeated units, spanning megabases in length. Given that the satDNA PboSat01-176, previously characterized in P. boiei, prompted ou...
