Plant Genomics MCP Tools (50)
ensembl_plants_lookup_locus
Fetch metadata for a plant locus identifier from Ensembl Plants. Defaults to arabidopsis_thaliana; pass organism= for other plant species (oryza_sativa, zea_mays, ...). Locus is the TAIR-style identifier (e.g. AT1G01010 for Arabidopsis NAC001).
get_gene_xrefs
Fetch cross-database references (UniProt, NCBI Gene, TAIR, ArrayExpress, …) for a plant locus from Ensembl Plants. Defaults to arabidopsis_thaliana; pass organism= for other Ensembl Plants species. Returns count + raw xref list + a by_db rollup keyed on Ensembl's dbname (e.g. 'Uniprot_gn', 'EntrezGene') for fast lookup of a single foreign identifier.
get_sequence
Fetch a locus's sequence from Ensembl Plants. seq_type is one of genomic / cds / cdna / protein (default protein — the canonical-transcript product). Closes the lookup → fetch → BLAST loop: feed the returned `sequence` straight to blast_sequence (protein for blastp, cds/cdna for blastn). Defaults to arabidopsis_thaliana; pass organism= for other plant species.
ensembl_region_query
List features overlapping a genomic interval via Ensembl Plants /overlap/region. region is the seq-region name (chromosome / contig, e.g. '1'); start and end are 1-based inclusive. feature is one of gene / transcript / cds / exon (default gene). Answers 'what genes are in this QTL interval / assembly window' without a per-locus lookup. Ensembl caps the span — oversized regions error. Defaults to arabidopsis_thaliana; pass organism= for other species.
phytozome_lookup_locus
Fetch a gene record from Phytozome BioMart (phytozome-next.jgi.doe.gov). Defaults to arabidopsis_thaliana; pass organism= for other Phytozome proteomes (slug, scientific/common name, or NCBI taxid — e.g. glycine_max, sorghum_bicolor). Locus is the source-genome gene name (e.g. AT1G01010, Glyma.01G000100). Returns organism_name, gene_name, chromosome, gene_start, gene_end, strand, description.
resolve_locus_to_uniprot
Resolve a plant locus to its canonical UniProtKB record. Prefers reviewed (Swiss-Prot) entries; falls back to unreviewed (TrEMBL) when no curated record exists (common for non-Arabidopsis plants). organism accepts a canonical slug, scientific/common name, or NCBI taxid (default arabidopsis_thaliana; e.g. oryza_sativa, zea_mays). Returns primaryAccession, uniProtkbId, entryType, recommendedName, geneNames, organism, taxonId, sequenceLength, web_url. This is the protein-side entry point — pair with InterPro / AlphaFold / Reactome / structural-bio tools.
locus_literature
Search Europe PMC for literature mentioning a plant locus. Free, no API key. Returns up to `size` results (default 10, capped at 25) with title, authors, journal, year, DOI, PMID, open-access status, citation count, and abstract. For non-Arabidopsis species the species common name is appended to the query to disambiguate locus IDs (rice, maize, ...). Pair with resolve_locus_to_uniprot or ensembl_plants_lookup_locus to ground the locus before fanning out to the literature.
locus_go_annotations
Fetch Gene Ontology annotations for a plant locus from QuickGO (EBI). Free, no API key. The locus is first resolved to a UniProt accession via the same logic as resolve_locus_to_uniprot, then QuickGO is queried by geneProductId. Returns annotations[] with goId/goName/goAspect/qualifier/evidence + a by_aspect rollup ({molecular_function: [{goId, goName}, ...], biological_process: [...], cellular_component: [...]}) deduped on goId so the high-level term set is one read away.
locus_plant_ontology
Fetch Plant Ontology (PO) + Trait Ontology (TO) + experimental-condition (PECO) annotations for a plant locus from Planteome (browser.planteome.org, AmiGO2/GOlr; free, no API key). Complements locus_go_annotations: QuickGO serves GO (species-agnostic), Planteome serves the plant-specific ontologies — PO (anatomy + developmental stage), TO (traits). The locus is matched across Planteome's searchable bioentity fields and filtered by the organism's NCBI taxon. Returns annotations[] (term_id / term_name / ontology / aspect / evidence / reference) + a by_ontology rollup ({PO: [{term_id, term_name}, ...], TO: [...], PECO: [...]}) deduped on term_id. Coverage is strong for arabidopsis, rice, maize, grape, soybean, tomato; other organisms return an empty list, not an error. Defaults to arabidopsis_thaliana; pass organism= for other species.
go_enrichment
GO + KEGG over-representation analysis for a gene LIST via g:Profiler g:GOSt (biit.cs.ut.ee/gprofiler; free, no API key). Unlike locus_go_annotations (one locus → its terms), this answers 'what is my gene SET enriched for?' — the dominant question for a differential-expression or co-expression cluster. loci is the query gene list (e.g. AT-codes for Arabidopsis, RAP-DB IDs for rice). sources defaults to GO:BP/GO:MF/GO:CC + KEGG; user_threshold is the g:SCS-corrected significance cutoff (default 0.05). Optional background sets a custom statistical domain (default: all annotated genes). Returns enriched[] (term_id/name/p_value/intersection_size/…, capped at top_n by p-value) plus unmapped[] — query loci g:Profiler could not recognize, surfaced so a locus-namespace mismatch is visible. Defaults to arabidopsis_thaliana; pass organism= for any of the 12 species.
gramene_homologs
Fetch orthologs and paralogs for a plant locus from Gramene compara (data.gramene.org v69). Default homology_type='ortholog'; pass 'paralog' for in-species duplicates or 'all' for everything. Returns target_locus + homology category (type) + shared gene_tree_id per hit. The fl=homology projection does not carry per-row taxon, identity, or protein ID; pair with resolve_locus_to_uniprot for protein-level enrichment and with blast_sequence for sequence similarity discovery.
kegg_pathways
Fetch KEGG pathway memberships for an Arabidopsis locus from rest.kegg.jp. Returns a list of pathway IDs + names + KEGG category classes the locus participates in. Pairs with locus_go_annotations for the GO-level functional view. Multi-organism caveat (v1.1.0): the organism= field accepts any plant in the matrix for symmetry with the other backends, but only arabidopsis_thaliana resolves — KEGG uses NCBI Entrez Gene IDs for rice/maize/etc. and our cross-backend locus contract can't produce those yet, so any other organism raises OrganismNotSupported before any HTTP call. KEGG v118+ is case-sensitive on the locus: pass AGI loci as uppercase.
