Weakly positioned nucleosomes enhance the transcriptional competency of chromatin. [PDF]
PLoS ONE, 2010 Transcription is affected by nucleosomal resistance against polymerase passage. In turn, nucleosomal resistance is determined by DNA sequence, histone chaperones and remodeling enzymes.

Investigation of distal repetitive sequences in the genus allium [PDF]
, 2009 PhDThe telomere is a DNA/protein structure required to maintain the ends of linear chromosomes. Usually the DNA component comprises a highly conserved tandemly repeated minisatellite sequence.

Ecological Adaptation Mechanisms Underlying Successful Plant Reproduction
Advanced Science, EarlyView.During floral induction, various environmental and endogenous signals converge to regulate the florigen protein, which is transported from leaves to the SAM to initiate flowering. Within the SAM, a complex network of receptor kinases and small peptides orchestrates floral development with high spatiotemporal precision.

H2A.Z nucleosome positioning has no impact on genetic variation in Drosophila genome. [PDF]
PLoS ONE, 2013 Nucleosome occupancy results in complex sequence variation rate heterogeneity by either increasing mutation rate or inhibiting DNA repair in yeast, fish, and human. H2A.Z nucleosome is extensively involved in gene transcription activation and regulation.

Fission yeast NUMTs are preferentially located in intergenic regions associated with replication origins [PDF]
, 2008 NUMTs are fragments of mtDNA that escaped from mitochondria to get inserted into nuclear DNA. NUMTs are present in almost all eukaryotic genomes sequenced so far and it has been proposed that our genome is being continuously colonized by mtDNA.

Advanced Science, EarlyView.Comparative genomics of Gondwana‐diverged Pila and Pomacea reveals parallel evolution of aerial oviposition. Convergent chromosomal rearrangements reshape regulatory landscapes within topologically associating domains. Lineage‐specific gene family expansions and viral‐derived perivitelline proteins (PV1) underpin desiccation resistance.

Crop Breeding and Applied Biotechnology, 2008 Intergenic spacers of chloroplast DNA (cpDNA) are very useful in phylogenetic and population genetic studies of plant species, to study their potential integration in phylogenetic analysis. The non-coding trnE-trnT intergenic spacer of cpDNA was analyzed

H2A.Z has a function reminiscent of an activator required for preferential binding to intergenic DNA [PDF]
The EMBO Journal, 2003 H2A.Z has been shown to regulate transcription in yeast, and that function resides in its C-terminal region as the reciprocal portion of H2A cannot substitute for the latter. We show that fusion of a transcriptional activating region to the C-terminal region of H2A, which is substituted for that of H2A.Z, can allow the chimera to fulfil the special ...
