Description

Perform a light-touch framing revision. The manuscript should acknowledge that interchromosomal subtelomeric sharing and ectopic exchange are established biology; its advance is the first chromosome-unrestricted, population-scale map of their extent, variation and organization across near-complete human assemblies. Replace the current abstract with the supplied Nature-style summary paragraph, retaining only essential numbers and omitting the implicit-graph sampling and transitive-closure details. Add one concise Introduction bridge connecting the 2023 acrocentric pangenome result and the complete Robertsonian assemblies to the present genome-wide generalization. Replace “fragmentary evidence” with “locus-specific and reference-limited,” and define the unresolved question as the population-scale extent and organization of the exchange landscape. Preserve the existing non-PHR flank control and cautious pedigree language. In the conclusion, remain assertive about recurrent ectopic exchange while avoiding the narrower claim that all maintenance occurs through classical NAHR. Do not add an explicit evidence-hierarchy paragraph, a catalogue of rejected alternative mechanisms, repeated qualifications, or new validation analyses. The goal is to correct the framing without changing the paper’s structure, emphasis or voice.

Use this Nature-style summary paragraph, 155 words excluding reference markers:

Human subtelomeres have long been known to contain duplicated sequence shared among non-homologous chromosome ends and to undergo ectopic exchange¹–⁶,¹⁹. However, incomplete reference assemblies and chromosome-partitioned analyses have prevented a population-scale view of the extent and organization of this system¹³–¹⁸. Here we show, using 465 near-complete human assemblies and chromosome-unrestricted pangenome analysis, that high-identity pseudo-homologous regions occur on 41 of 48 chromosome arms. They form structured sequence communities in which established exchange systems appear as local peaks within a broader continuum. Human and mouse chromosome-contact maps show preferential proximity between sequence-similar ends, and in human data this relationship persists in adjacent flanks lacking the homology used to define the pairs. A three-generation pedigree assembled end to end contains candidate exchange patches enriched within the same communities. These results generalize known subtelomeric exchange systems into a near-ubiquitous population-scale architecture and establish recurrent ectopic exchange as a genome-wide force in the concerted evolution of human chromosome ends.

Additional housekeeping correction: Figure 4C, its legend/caption and the Results must agree on whether the plotted mouse trajectory is per-PHR-pair or arm-pair-collapsed. Inspect the actual figure/source/manuscript wording and make them consistent without inventing new analysis.

Validation

  • submission/paper.tex uses a Nature-style bold opening summary paragraph and removes the Keywords line if present.
  • The summary paragraph is referenced appropriately in LaTeX and omits implicit-graph sampling/transitive-closure machinery.
  • Introduction includes one concise bridge from the 2023 acrocentric pangenome result and 2025 complete Robertsonian assemblies to the present genome-wide generalization.
  • “fragmentary evidence” is replaced with “locus-specific and reference-limited.”
  • The unresolved question is framed as population-scale extent, variation and organization, not pedigree event validation.
  • Conclusion uses recurrent ectopic exchange language rather than a narrow all-NAHR maintenance claim.
  • Non-PHR flank control and cautious pedigree language are preserved, not multiplied.
  • Figure 4C Results text and caption agree with the actual aggregation level.
  • Gomes de Lima et al. 2025 Robertsonian Nature paper is in submission/bibliography.bib if not already present.
  • Build from submission succeeds with guix shell texlive -- make, and final paper.log has zero undefined hits.
