  1. ...the reporters are expressed at low level in spite of a euchromatic environment. Our model of birth-diffusion-death on chromatin suggests that some ratelimiting factor is released near the promoters and especially the terminators of active genes. The RNA polymerase itself is a poor candidate for this role...
  2. ...RNAs (17%) are lineage-specific (P < 10#2;10, Fisher’s exact test). Furthermore, the new loci detected here are characterized by low expression levels (see also below), which likely explains why they have previously remained undetected. Birth and death rates of miRNAs in mammals With our sets of miRNA gene...
  3. ...adaptive immunity, and MHC genes serve as key models in evolutionary genomics, offering insight into birth-and-death evolution, gene duplication, and the maintenance of genetic diversity. However, the organization and evolution of the MHC in species with giant s, such as salamanders, remain poorly...
  4. ...to chromosomes, whether spontaneous or induced by external agents, often result in abnormal cell division and aneuploidy, conditions frequently observed in cancer cells (Bakhoum and Cantley 2018). Moreover, chromosome rearrangements post-DNA breakage are well-documented and contribute significantly to evolution...
  5. ...Clusters of Resistance Genes in Plants Evolve by Divergent Selection and a Birth-and-Death Process Richard W. Michelmore 1 and Blake C. Meyers Department of Vegetable Crops, University of California, Davis, California 95616 USA Abstract Classical...
  6. ...and contractions along the Pezizales phylogeny. At each node, the top number indicates the number of gene-family expansions, and the bottom number indicates the number of contractions. The numbers in parentheses represent the significantly expanded and contracted gene families. (λ) Birth–death model rates fitted...
  7. ...-Robertson 2012) include epigenetic events such as methylation turnover (Ginno et al. 2020), replication and spatial chromatin changes (Candelli et al. 2018), the birth and death of promoters or their interconversion into enhancers (Majic and Payne 2020) and their putative bidirectional functioning (Young et al...
  8. .... First, we adapted and applied a phylogenetic modeling approach to quantitatively compare epigenomic signals at orthologous regulatory elements and identified thousands of promoter and enhancer regions with differential epigenomic activity in mole-rats. These elements associate with known mole...
  9. ...with high-quality long-read assemblies. We perform annotations of ovary piCs and -wide TE content in each strain. Our analysis uncovers extensive variation in piC activity across strains and signatures of rapid birth and death of piCs. Most TEs inferred to be recently active show an enrichment of insertions...
  10. ...). Similarly, engineering of human dicentric chromosomes lead to a variety of consequences, including centromere inactivation (Higgins et al. 2005). Together, these studies indicate that chromosome rearrangements can be associated with the rapid birth and death of centromeres in plants and animals, further...
