Within the framework of the CSP 'Metatranscriptomics of Forest Soil Ecosystems' project, we are aiming to explore the interaction of forest trees with communities of soil fungi, including ectomycorrhizal symbionts that dramatically affect tree growth, and saprotrophic soil fungi impacting carbon sequestration in forests. We are sequencing the genome of the most abundant fungal species harvested on studied long-term observatories to provide sufficient taxonomic coverage of fungal genomes to identify and analyze DNA and RNA samples sequenced from environmental samples.
Marasmius fiardii
Marasmius fiardii belongs to a group of
litter-decomposing fungi recognizable by their small, parasol-like
caps, white spore print, thin, fragile stipes and often strong
coloration. The genus Marasmius has over 500 described
species, with most of its diversity centered to tropical areas,
where it's one of the most important microorganisms that
reintroduce fallen leaves into the carbon cycle. They are often
found on small twigs, leaves, although some species are thought to
form mutualistic interactions with grasses.
The genome sequence of M. fiardii fills an important gap
in the genomic catalogue of mushroom forming fungi. It's a
representative of the Marasmiaceae, a hyper diverse clade of mostly
litter-decomposing fungi with a world-wide distribution. As a
representative of this large group, the genome of M.
fiardii will contribute to our understanding of the
biochemical and enzymatic properties of litter decomposers and
their role in terrestrial ecosystems and global carbon
cycling.
The 'Metatranscriptomics of Forest Soil Ecosystems'
project is a large collaborative effort, led by the PI of this
project, Francis Martin (INRA), aiming for master publication(s).
