Apiosordaria backusii CBS 540.89

This genome was sequenced as part of the JGI CSP 1KFG - Deep Sequencing of Ecologically-relevant Dikarya, whose goal is to fill in gaps in the Fungal Tree of Life by sequencing at least two reference genomes from the more than 500 recognized families of Fungi. This project additionally aims to inform research on plant-microbe interactions, microbial emission and capture of greenhouse gasses, and environmental metagenomic sequencing.

The sequenced Apiosordaria backusii isolate CBS 540.89 has been isolated from dung of rabbit. It belongs to Lasiosphaeriaceae IV sensu Kruys, Huhndorf et al. (2015), which is closely related to thermophilic Chaetomiaceae. Sordariales is a taxonomically rich group containing ca. 35 genera (Huhndorf, Miller et al. 2004, Kruys, Huhndorf et al. 2015), spanning more than 75 million years of association with plant biomass (Saupe, Clavé et al. 2000). Sordariales can be sampled on a range of substrates such as dung, wood, leaves, litter, burned vegetation, biological soil crusts and soil; most are saprobes, but some live in close association with plants as endophytes and few have been described as pathogens. Sordariales also exhibit striking differences in temperature requirements, ranging from mesophilic to thermophilic. Unraveling the genomic features reflecting their ability to efficiently forage their substrate will represent foundational information for understanding the role of saprophilous, lignicolous, herbicolous and coprophilous fungi in nutrient and energy flows within ecosystems. In addition, these resources will facilitate the rational design of improved thermophilic and/or biomass degrading fungal host strains, and help field studies aiming to predict responses of fungal communities to environmental changes, such as global warming.
