What is iGenolevures (iGNL)?

We are an international consortium of yeast geneticists and genomicians, supported by the CNRS and the INRA. We have put together a network of databases concerning various aspects of yeast genomics, on the same set of genomes. We also organize open meetings on yeast genomics.

iGNL Databases

GRYC: searchable gene pages, genome pages and download, blast server and Genome Browser.
Phylome DB: complete catalogs of gene phylogenies (phylomes), visualization of phylogenetic trees.
FUNGIpath: exploration of metabolic pathways, with EC numbers and gene names, using prediction of orthologous protein groups.

iGNL criteria for genomes

We include in the iGNL databases, publicly available yeast genomes, according to the following criteria: an assembly made up of large scaffolds (>100 kb, ideally one scaffold per chromosome), and an annotation of good quality (we may re-annotate some genomes). Yeasts may include species from all clades of the fungal kingdom.


37 genomes from 35 species belonging to 17 Saccharomycotina genera are in the GRYC db and explored in the phylomeDB and FUNGIpath db.
