Plant immune receptor database.
We're building an open catalog of plant defense mechanisms — mining PRRs (pattern recognition receptors) across hundreds of genomes to map the full landscape of natural disease resistance.
Last updated: May 4, 2026
Genome accessions indexed
From GenBank (795) and RefSeq (233), spanning 644 unique plant species.
Genomes fully processed
42 successful + 25 passed quality filters. 842 additional accessions pending annotation.
PRRs identified
Pattern Recognition Receptors: 11,761 receptor-like kinases (RLKs) and 5,593 receptor-like proteins (RLPs).
Unique plant species
Across 4 lineages: eudicots, monocots, embryophytes, and chlorophytes.
Processing pipeline
1,028 genome accessions from GenBank and RefSeq — quality-filtered with BUSCO and Compleasm before PRR annotation.
Top species by PRR count
PRRs per genome range from 4 to 553 (mean: 266). Highest counts in Brassicaceae and Camellia species.
Lineage coverage
Taxonomic breadth of processed genomes across major plant lineages.
PRR composition
Receptor types across all 17,354 identified PRRs.
What's next
842 genome accessions are queued for processing — representing 547 additional species. As our annotation pipeline scales, we expect the PRR catalog to grow from 17,000 to over 100,000 receptors, dramatically expanding the search space for disease-resistant variants.
Expand coverage
Process all 842 pending genomes, prioritizing major food crops and their wild relatives.
Cross-species transfer
Immune receptors in one crop often have functional homologs in others — one discovery can protect dozens of species.
Pathogen mapping
Map receptor-pathogen interactions across bacterial, fungal, and oomycete threats to build a comprehensive defense atlas.
