The arrangement of Brachypodium distachyon chromosomes in interphase nuclei
The spatial organization of chromatin within the interphase nucleus and the interactions between chromosome territories (CTs) are essential for various biological processes, such as DNA replication, transcription, and repair. However, detailed data about the CT arrangement in monocotyledonous plants are scarce. In this study, chromosome painting was used to analyse the distribution and associat...
متن کاملChromobility: the rapid movement of chromosomes in interphase nuclei.
There are an increasing number of studies reporting the movement of gene loci and whole chromosomes to new compartments within interphase nuclei. Some of the movements can be rapid, with relocation of parts of the genome within less than 15 min over a number of microns. Some of these studies have also revealed that the activity of motor proteins such as actin and myosin are responsible for thes...
متن کاملPhosphatidylserine colocalizes with epichromatin in interphase nuclei and mitotic chromosomes
Cycling eukaryotic cells rapidly re-establish the nuclear envelope and internal architecture following mitosis. Studies with a specific anti-nucleosome antibody recently demonstrated that the surface ("epichromatin") of interphase and mitotic chromatin possesses a unique and conserved conformation, suggesting a role in postmitotic nuclear reformation. Here we present evidence showing that the a...
متن کاملVisualization of interphase chromosomes.
Using a modified Giemsa-banding technique we have observed what appear to be chromosomes during interphase in nuclei from Allium cepa root tips and Chinese hamster cells (CHO line). During telophase through G1 chromosomes progressively uncoil and decondense. During S chromosomes are comparatively decondensed, but some segments have structure similar to chromosomes in G1 and G2. During G2 the ch...
متن کاملInterphase chromosomes and the Rabl configuration: does genome size matter?
Summary It is now well established that the cereals share a common gene order or gene synteny. However, the cereal species encompass an enormous range of genome size, with wheat being one of the largest and rice one of the smallest. Here we describe the current state of knowledge of interphase chromosome structure within the cereal species. In wheat and its close relatives, the interphase chrom...
