Migration of repetitive DNAs during evolution of the permanent translocation heterozygosity in the oyster plant (Tradescantia section Rhoeo) [0.03%]
永久移位杂合性进化过程中重复DNA的迁移——以吊兰（ Tradescantia 捻子草组）为例

Hieronim Golczyk et al.
Due to translocation heterozygosity for all chromosomes in the cell complement, the oyster plant (Tradescantia spathacea) forms a complete meiotic ring. It also shows Rabl-arrangement at interphase, featured by polar centromere clustering. ...
Allele segregation analysis of F1 hybrids between independent Brassica allohexaploid lineages [0.03%]
独立二倍体物种间allohexaploid品系的F1杂种单株标记基因分型及分离分析

Daniela Quezada-Martinez et al.
In the Brassica genus, we find both diploid species (one genome) and allotetraploid species (two different genomes) but no naturally occurring hexaploid species (three different genomes, AABBCC). Although hexaploids can be produced via huma...

Advances in genome sequencing have revealed a type of extrachromosomal DNA, historically named double minutes (also referred to as ecDNA), to be common in a wide range of cancer types, but not in healthy tissues. These cancer-associated cir...
Kinesin-5 Eg5 mediates centrosome separation to control spindle assembly in spermatocytes [0.03%]

Timely and accurate centrosome separation is critical for bipolar spindle organization and faithful chromosome segregation during cell division. Kinesin-5 Eg5 is essential for centrosome separation and spindle organization in somatic cells;...
Germline-restricted chromosome shows remarkable variation in size among closely related passerine species [0.03%]
近缘雀形目物种中谱系限制型染色体大小差异显著
Manuelita Sotelo-Muñoz,Manon Poignet,Tomáš Albrecht et al.
Manuelita Sotelo-Muñoz et al.
Passerine birds have a supernumerary chromosome in their germ cells called the germline-restricted chromosome (GRC). The GRC was first discovered more than two decades ago in zebra finch but recent studies have suggested that it is likely p...
Multiple heterochromatin diversification events in the genome of fungus-farming ants: insights from repetitive sequences [0.03%]
菌根蚂蚁基因组中的多个异染色质分化事件：来自重复序列的见解
Gisele Amaro Teixeira,Luísa Antônia Campos Barros,Hilton Jeferson Alves Cardoso de Aguiar et al.
Gisele Amaro Teixeira et al.
A substantial portion of the eukaryotic genome includes repetitive DNA, which is important for its stability, regulation, and architecture. Fungus-farming ant genomes show remarkable structural rearrangement rates that were necessary for th...
The N-terminal domain of TET1 promotes the formation of dense chromatin regions refractory to transcription [0.03%]
TET1的N端结构域促进转录抵抗性致密染色质区域的形成
Audrey Lejart,Siham Zentout,Catherine Chapuis et al.
Audrey Lejart et al.
TET (ten-eleven translocation) enzymes initiate active cytosine demethylation via the oxidation of 5-methylcytosine. TET1 is composed of a C-terminal domain, which bears the catalytic activity of the enzyme, and a N-terminal region that is ...
Satellitome analysis illuminates the evolution of ZW sex chromosomes of Triportheidae fishes (Teleostei: Characiformes) [0.03%]
卫星基因组分析揭示Characiformes鱼总目Triportheida科ZW性染色体的进化
Rafael Kretschmer,Caio Augusto Gomes Goes,Luiz Antônio Carlos Bertollo et al.
Rafael Kretschmer et al.
Satellites are an abundant source of repetitive DNAs that play an essential role in the chromosomal organization and are tightly linked with the evolution of sex chromosomes. Among fishes, Triportheidae stands out as the only family where a...
NucPosDB: a database of nucleosome positioning in vivo and nucleosomics of cell-free DNA [0.03%]
NucPosDB：染色质结构与细胞游离DNA核小体定位数据库
Mariya Shtumpf,Kristan V Piroeva,Shivam P Agrawal et al.
Mariya Shtumpf et al.
Nucleosome positioning is involved in many gene regulatory processes happening in the cell, and it may change as cells differentiate or respond to the changing microenvironment in a healthy or diseased organism. One important implication of...
Incorporation of CENP-A/CID into centromeres during early Drosophila embryogenesis does not require RNA polymerase II-mediated transcription [0.03%]
RNA聚合酶II介导的转录非早期果蝇胚胎着丝粒处CENP-A/CID整合所必需
Samadri Ghosh,Christian F Lehner
Samadri Ghosh
In many species, centromere identity is specified epigenetically by special nucleosomes containing a centromere-specific histone H3 variant, designated as CENP-A in humans and CID in Drosophila melanogaster. After partitioning of centromere...
