The CentO satellite confers translational and rotational phasing on cenH3 nucleosomes in rice centromeres.
Plant and animal centromeres comprise megabases of highly repeated satellite sequences, yet centromere function can be specified epigenetically on single-copy DNA by the presence of nucleosomes containing a centromere-specific variant of histone H3 (cenH3). We determined the positions of cenH3 nucleosomes in rice (Oryza sativa), which has centromeres composed of both the 155-bp CentO satellite ...
متن کاملBinding of NF1 to the MMTV promoter in nucleosomes: influence of rotational phasing, translational positioning and histone H1.
To analyse the role of rotational orientation and translational positioning of nucleosomal DNA on transcription factor binding we have generated a series of mutant MMTV promoters containing insertions of various lengths between the hormone-responsive region and the binding site for NF1. These various MMTV promoter fragments were assembled in mononucleosomes and used for structural studies and b...

the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
15 صفحه اولGenomic and genetic characterization of rice Cen3 reveals extensive transcription and evolutionary implications of a complex centromere.
The centromere is the chromosomal site for assembly of the kinetochore where spindle fibers attach during cell division. In most multicellular eukaryotes, centromeres are composed of long tracts of satellite repeats that are recalcitrant to sequencing and fine-scale genetic mapping. Here, we report the genomic and genetic characterization of the complete centromere of rice (Oryza sativa) chromo...
متن کاملGlobal sequence characterization of rice centromeric satellite based on oligomer frequency analysis in large-scale sequencing data
MOTIVATION Satellite DNA makes up significant portion of many eukaryotic genomes, yet it is relatively poorly characterized even in extensively sequenced species. This is, in part, due to methodological limitations of traditional methods of satellite repeat analysis, which are based on multiple alignments of monomer sequences. Therefore, we employed an alternative, alignment-free, approach util...
