Recently, National Renewable Energy Laboratory scientists proposed a novel concept to develop a model fungal cellulase producer Trichoderma reesei as the fungal CBP platform for economic lignocellulosic biofuel production.
Two model fungal strains, the wild type of Neurospora crassa – a commonly used model organisms – and the ro-1 mutant strain of this species impaired in hyphal growth and morphology, have been chosen to demonstrate the potential of this new methodology.
Here, we use a model fungal system to test the hypothesis that intraspecific genotypic richness of Paxillus obscurosporus stimulates biomass and CO2 efflux, but that this is dependent on nitrogen supply.
In this model, fungal biofilms are formed on the bottom of the wells of microtiter plates, and the ability of metabolically active sessile cells to reduce a tetrazolium salt (XTT) to water-soluble orange formazan compounds, the intensity of which can then be determined using a microtiter-plate reader, is used as a semi-quantitative measurement of biofilm formation.
For example, the two major model fungal species, Saccharomyces cerevisiae and Schizosaccharomyces pombe, do not have PARPs.
C. neoformans has been considered an excellent model fungal pathogen to study iron transport and homeostasis because of its intriguing connection with virulence.
Another study screened a model fungal plant-type chitinase, Saccharomyces cerevisiae CTS1 (ScCTS1) against a library containing 880 off-patent drugs [25].
Interestingly, many of the fungi that have lost all PARPs, including the model fungal systems Saccharomyces cerevisiae and Schizosaccharomyces pombe, are yeasts.
Although this is the first molecular characterization of sexual reproduction in Pseudogymnoascus, much is known about the molecular pathways in other model fungal systems such as Saccharomyces cerevisiae, Neurospora crassa, Aspergillus nidulans, and others (Dyer and O'Gorman 2012).
Most of the experimental characterization of gene function has been performed in a small number of model fungal systems, which can provide an anchor for these broad genome sequencing surveys.
Larvae from the FS lines reared in the presence of the model fungal competitor, A. fumigatus had no higher survival than larvae from UC lines (FS mean = 0.23, SE = 0.03; UC mean = 0.16, SE = 0.03, F1,4 = 2.25, p = 0.2080).
