[ensembl-dev] Gene ID <-> Gene Ontology mapping with REST or BioMart API

[Thomas Maurel]

Dear Joël,

In EnsemblGenomes Plant GOSlim data is only available for Hordeum vulgare at the moment (plants mart 24). 
In Ensembl, we have GOSlim data available for our 69 species (ensembl mart 77).

Hope this helps,
Regards,
Thomas
