Exploring the Mycorrhizal Genomes

I hope you are wrapping up a good summer. I’m touching base to update you on our Mycorrhizal Genomics Initiative (MGI).

The list of taxa of mycorrhizal fungi for the first series of analyses aiming to identify symbiotic traits has now been “frozen”. Thanks to Igor Grigoriev’s JGI team, this list includes an outstanding series of annotated genomes and transcriptomes from ectomycorrhizal, ericoid and orchid symbionts:

  • Amanita muscaria Koide
  • Hebeloma cylindrosporum h7  (v2.0),
  • Laccaria bicolor (v2.0),
  • Oidiodendron maius Zn,
  • Paxillus involutus,
  • Paxillus rubicundulus,
  • Piloderma croceum F 1598,
  • Pisolithus microcarpus 441,
  • Pisolithus tinctorius 270,
  • Scleroderma citrinum FougA,
  • Sebacina vermifera MAFF 305830,
  • Suillus luteus UH-Slu-Lm8-n1,
  • Tulasnella calospora AL13/4D,

In addition, the following available transcriptomes will also be mined for symbiotic-related features:

  • Cenococcum geophilum
  • Cortinarius glaucopus,
  • Laccaria amethystina 08-1,
  • Lactarius quietus,
  • Meliniomyces bicolor,
  • Meliniomyces variabilis, and
  • Tricholoma matsutake 945.

Finally, we will add the unpublished genomes of five saprotrophic agaricomycotina (including leaf-litter species) that we will use for identifying potential common genomic features in litter-borne and mycorrhizal fungi:

  • Jaapia argillacea MUCL-33604,
  • Hydnomerulium pinastri MD-312,
  • Plicaturopsis crispa FD-325 SS-3,
  • Hypholoma sublateritium FD-334 SS-4, and
  • Gymnopus luxurians FD-317 M1

JGI has (or will soon) publicly released the web portals with the annotation for the above-mentioned fungal species. Visit the JGI Mycocosm database. In addition, we have released web sites for the corresponding transcriptome annotation at the Mycorhiza Genomics Initiative portal [restricted].

To make good use of this tremendous genomic resource, we are organizing the 2nd MGI Workshop at the INRA-Nancy center in Champenoux (France), on November 13-14, 2012. The aim of the workshop is to bring together the consortium teams for discussing our findings. The format of the workshop will be roughly equally split between informal presentations summarizing the current findings and brainstorming about how to take advantage of the genome sequences to inform our understanding of symbiosis and fungal biology.

On the following days, we will organize a New Phytologist Workshop entitled ‘ Bridging Mycorrhizal Genomics, Metagenomics & Forest Ecology‘. The workshop will also take place at INRA-Nancy over two days (Thursday 15 & Friday 16 November). The aim is to bring together a small group of MGI PI’s, fungal biologists and ecologists (20-25 attendees) to explore the future use of mycorrhizal genomes in order to both maximize the efficacy with which the community utilizes these technological breakthroughs in biology, ecology, phylogenetics, and forestry.
