Thozetella is an anamorphic genus belonging to the Chaetosphaeriaceae originally described by Berkeley (1881) from fungal fruitings found on dead bark and sticks in tropical Australia. Their condidiomata are characterized with distinctive microawns and curved unbranched setulae on each end of their conidia. These fungi are widespread in tropical and temperate regions globally and are most often associated with leaf litter and dead plant matter (Jeewon et al., 2009). However, some species of Thozetella have been isolated from roots of living plants (Waipara et al., 1996) and the hyphae of these fungal endophytes can penetrate epidermal and cortical root tissue of seedlings without causing visible disease symptoms. The isolate sequenced here was isolated as a root endophyte of Populus, an important bioenergy crop. This species is being studied by the DOE Plant-Microbial Interfaces project aimed at understanding the molecular interactions between Populus and its symbionts.
