“…Observing chromosome dynamics during the earlier steps of HR, mainly the resection from DSB ends that generates recombinogenic single strands, requires a visualization system that does not interfere with the process, and is small relative to the few kilobases of DNA that undergo processing. Current visualization tools, based on binding of fluorescent repressor proteins to arrays of specific binding sites, have the major drawback that highly-repeated DNA and lengthy stretches of strongly bound protein can obstruct chromatin function. …”

“…Examining signal-responsive (Hypoxia Inducible Factor) genes showed that 97% were within 50 kilobases of an inducible CBP peak, and 70% of these required CBP/p300 for full induction. …”

“…Most of these variants map to non-protein-coding regions and several map to gene deserts, regions of several hundred kilobases lacking protein-coding genes. We hypothesized that gene deserts harbor long-range regulatory elements that can physically interact with target genes to influence their expression. …”

“…We unexpectedly found that 350 kilobases of dynamic LS regions were much more conserved than the core genome between V. dahliae and a closely related species (V. albo-atrum), suggesting that these LS regions were horizontally transferred recently. …”

“…CPT-seq is an entirely in vitro means of generating libraries comprised of 9216 indexed pools, each of which contains thousands of sparsely sequenced long fragments ranging from 5 kilobases to >1 megabase. These pools are “subhaploid,” in that the lengths of fragments contained in each pool sums to ∼5% to 10% of the full genome. …”

“…Yet these signals of selection were inconsistent and sometimes weak tens of kilobases from Ace-1. This unexpected finding is attributable to apparently ubiquitous amplification of 119S alleles as part of a large copy number variant (CNV) far exceeding the size of the Ace-1 gene, whereas 119G alleles were unduplicated. …”
