Dynamic Organization of Chromatin Domains Revealed by Super-Resolution Live-Cell Imaging.
The eukaryotic genome is organized within cells as chromatin. For proper information output, higher-order chromatin structures can be regulated dynamically. How such structures form and behave inExpand

Chromatin as dynamic 10-nm fibers
Since Flemming described a nuclear substance in the nineteenth century and named it “chromatin,” this substance has fascinated biologists. What is the structure of chromatin? DNA is wrapped aroundExpand

Nucleosomal arrays self‐assemble into supramolecular globular structures lacking 30‐nm fibers
The existence of a 30‐nm fiber as a basic folding unit for DNA packaging has remained a topic of active discussion. Here, we characterize the supramolecular structures formed by reversibleExpand

Single nucleosome imaging reveals loose genome chromatin networks via active RNA polymerase II
Although chromatin organization and dynamics play a critical role in gene transcription, how they interplay remains unclear. To approach this issue, we investigated genome-wide chromatin behaviorExpand

A Transient Rise in Free Mg2+ Ions Released from ATP-Mg Hydrolysis Contributes to Mitotic Chromosome Condensation
For cell division, negatively charged chromatin, in which nucleosome fibers (10 nm fibers) are irregularly folded [1-5], must be condensed into chromosomes and segregated. While condensin and otherExpand

The physical size of transcription factors is key to transcriptional regulation in chromatin domains.
Genetic information, which is stored in the long strand of genomic DNA as chromatin, must be scanned and read out by various transcription factors. First, gene-specific transcription factors, whichExpand

Density imaging of heterochromatin in live cells using orientation-independent-DIC microscopy
Using orientation-independent-DIC microscopy, we revealed that the density of total materials in heterochromatin was only 1.53-fold higher than that of euchromatin, whereas the DNA density wasExpand

Taxonomy and geographical distribution of Dugesia japonica and D. ryukyuensis in the Far East
Dugesia japonica Ichikawa et Kawakatsu, 1964, is a common and polymorphic species of freshwater planarian distributed widely in the Far East. In 1976 the geographic populations were separated into 2Expand

A review of chromosomal variation in Dugesia japonica and D. ryukyuensis in the Far East
The chromosome numbers of Dugesia japonica Ichikawa et Kawakatsu, 1964, are n = 8, 2x = 16 and 3x = 24; those of Dugesia ryukyuensis Kawakatsu, 1976, are n = 7, 2x = 14 and 3x = 21. The karyotypes ofExpand
