  1. ...and after centromere damage. Expanded centromeric domains remodeled to adopt a more open configuration, whereas contracted domains become more compact in CSDt lines (Fig. 5D). These findings indicated that centromeric chromatin is remodeled to maintain functionality following structural change. Similarly...
  2. ...interspecies crossing, showed that regions of CENH3 ChIP-seq enrichment expanded from ∼1.8 Mb to ∼3.6 Mb, once in an oat nucleus (Jin et al. 2004; Wang et al. 2014). This indicates that the nuclear context, and likely trans-acting factors, can influence CENH3 occupancy on centromeric DNA sequences...

  3. ...to complex regions like centromeres, composed of extra-long tandem repeats (ETRs). However, a significant gap remains as current methodologies are inadequate for producing sequence alignments that effectively capture genetic events within ETRs, highlighting a pressing need for improved alignment tools...
  4. ...clinical isolate, indicating that SVs represent a significant source of intraspecies genetic variation. We identify multiple, distinct SVs at the centromeres of Chromosome 4 and Chromosome 5, including inversions and transposon polymorphisms. These two chromosomes are often aneuploid in drug...
  5. ...of highly uniform dimers flanked by more divergent dimers. An elevated mutational divergence was found between centromeres, two- to fourfold higher than at random loci, consistent with an error-prone repair process such as BIR. The investigators proposed a model in which highly identical repeats expand...

  6. ...content across 26 maize s, we developed panEDTA (Supplemental Code), which produces uniform TE annotations in a pan context (Fig. 1A). panEDTA is freely available at GitHub (https://github.com/oushujun/EDTA) and has been implemented in the browser-accessible, cloud-based platform Galaxy (The Galaxy...
  7. ...identification (Li et al. 2018b). This method has been applied in a sorghum biparental population (Li et al. 2018b; Mu et al. 2022), a rice backcross population (Guo et al. 2020), elite lines in wheat (Li et al. 2022), and diversity panels in maize, wheat, and oat (Li et al. 2021).We examined phenotypic...
  8. ...this method to the same set of 373,485 features as RNAfold but also to a larger, updated version of maize TE annotations (Stitzer et al. 2021), resulting in an expanded data set of 467,255 features (Table 2).For each sequence, LinearPartition calculated the partition function, summarized by the parameter Q...
  9. ...@uga.eduAbstractThe s of maize and other eukaryotes contain stable haplotypes in regions of low recombination. These regions, including centromeres, long heterochromatic blocks, and rDNA arrays, have been difficult to analyze with respect to their diversity and origin. Greatly improved assemblies are now available...
