Across plant genomes, WGD and other duplication modes leave distinct, lineage-biased duplicate landscapes.

Structured fields used in claim comparison tables when every cited study has a complete layer.

Key findings

Recent WGDs retain more WGD pairs; Brassicas show frequent WGT; modes vary by clade.

Methodology

Classified duplicates in 141 plant genomes into WGD, tandem, proximal, transposed, and dispersed classes.

Limitations

Classification depends on algorithms/parameters; not every pair’s function is tested.

Role on claims

Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.

  • SupportsBiodiversityconcept

    Multiple empirical papers in this library examine biodiversity with mechanistic biological findings.

    Evidence for the claim as stated.

  • SupportsBiodiversityconcept

    Recent WGDs retain more WGD pairs; Brassicas show frequent WGT; modes vary by clade.

    Evidence for the claim as stated.

  • SupportsBiodiversityconcept

    Systems and scales differ across biodiversity studies (species, tissues, methods), so mechanisms should not be over-generalised.

    Evidence for the claim as stated.

Open questions

Tensions this paper is part of

From concept pages' “where studies disagree.” Disagreement means the same question; scope means different assays, populations, or outcomes.
