Laccaria Bicolor

Laccaria bicolor DB Home

Welcome to LaccariaDB, the Laccaria bicolor database Version 3.0.


The symbiotic fungus Laccaria bicolor (common name: bicoloured deceiver) is a member of the Hydnangiaceae, a large order of ectomycorrhizal and saprobic basidiomycetes. Laccaria is a cosmopolitan and common genus of Agaricales which has been reported from numerous ectomycorrhizal plant communities. The systematics, biogeography, and ecology of this group of symbionts have been well-studied.

The INRA Laccaria bicolor Gene Index integrates research data from Laccaria bicolor EST and gene sequencing. The ultimate goal of this database is to collect a non-redundant set of all Laccaria bicolor genes and data on their expression patterns, cellular roles, functions, and evolutionary relationships.

LaccariaDB contains 14,312 tentative consensus (TCs) assembled from 38,901 ESTs representing the transcriptome of Laccaria bicolor and 20,614 JGI predicted gene models from the WGS.

The ESTs derived from cDNA libraries of vegetative mycelium, mycelium grown in the presence of Populus roots, ectomycorrhizas of Populus/S238N and fruiting bodies of S238N. EST sequences qualified to be part of the TC Unigene pool were assembled by Peter Brokstein at JGI with MALIGN assembly program (99% identity, end-pairs always in same cluster). EST datasets contains ESTs from JGI, Genoscope and INRA. The JGI gene models were downloaded from the JGI Laccaria portal.
