PGDD 2.0: Plant Genome Duplication Database with updated content and tools.
Article in Nucleic acids research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Polyploidy and small-scale duplication have repeatedly reshaped plant genomes, making synteny and colinearity indispensable for evolutionary inference. We present PGDD 2.0 (accessible at chibba.agtec.uga.edu and pgdd2.org), a major update to the Plant Genome Duplication Database (PGDD) that now aggregates >120 complete telomere-to-telomere (T2T) assemblies, including many chromosome-scale genomes spanning all major Viridiplantae lineages. Each genome sequence is processed with a standardized pipeline to call intra- and intergenomic colinear (syntenic) blocks, estimate Ks, and block score metrics and age distributions. PGDD 2.0 introduces (i) interactive synteny networks for pattern discovery across taxa, (ii) a "riparian" or synteny alignment view for visualizing mesosynteny and rearrangements, and (iii) an embedded SynVisio module for rendering user-supplied or PGDD-downloaded MCScanX results directly in the browser. Together, these advances support tasks from resolving ancient whole-genome duplication signatures to tracing the postduplication fates of specific gene families with T2T-level precision and beyond. PGDD 2.0 delivers an up-to-date, uniform, and user-centered platform for plant comparative genomics, accelerating discovery regarding polyploidy, gene duplication, and genome evolution.
