1. Introduction
Enzymatic conversion of lignocellulosic biomass (i.e. plant material) to bio-products is of great interest for the development of sustainable biorefineries. Plant biomass constitutes the most abundant biological repository of carbon on Earth. It is a complex structure comprising polysaccharides (cellulose, hemicellulose, pectin) and lignin, forming a tight interconnected network. This heterogeneous composition makes it recalcitrant to biotic degradation, which in turn hampers the development of bioprocesses for industrial purposes (Himmel et al., 2007). Because of its complex structure, a number of enzymes with diverse complementary activities are required to perform efficient conversion of plant cell wall to platform molecules or high value compounds, and considerable research efforts have aimed at developing such efficient enzyme systems from microbes. Filamentous fungi thrive in lignocellulose-rich environments because they are potent biomass degraders thanks to their dedicated enzymatic machinery (Sigoillot et al., 2012) and their ability to penetrate forcibly the biomass. Among them, the filamentous ascomycete fungus Podospora anserina has been studied for decades as a model species and numerous studies focused on biological questions such as ageing (Osiewacz et al., 2013), prion mechanisms (Baxa et al., 2004) or fungal reproduction (Silar, 2014; Debuchy et al., 2010). Indeed, genetic analysis is efficient with P. anserina thanks to its one-week haplophasic life cycle (Silar, 2013a,b). Moreover, this fungus is easily transformed by exogenous DNA and its genes can be inactivated in one step by replacement with resistance markers (Silar, 2013a,b). One of the outcomes of the genome sequence project of this species (Espagne et al., 2008) was the discovery of a large array of enzymes potentially involved in both cellulose and lignin breakdown, making this fungus a model of choice to better understand the enzymatic deconstruction of plant biomass. In its natural environment, P. anserina is a cosmopolitan coprophilous fungus which frequently develops in the droppings of grass herbivores. As a very late ascomycete degrader that fructifies after the succession of most other coprophilous organisms, P. anserina is thought to specifically use the more recalcitrant fraction of lignocellulose (Richardson, 2002). In line with this assumption, this fungus can fructify abundantly using lignocellulosic biomass as sole carbon source (Fig. 1). In addition, it was demonstrated that P. anserina differentiates dedicated hyphae to penetrate the biomass, facilitating its digestion (Brun et al., 2009). Development of these hyphae is under the control of signalling pathways that also regulate the transcription of lignocellulolytic genes, connecting differentiation and enzyme production (Bidard et al., 2012). In this article, we review genomic and post-genomic studies, as well as biochemical and genetic analyses focusing on the exploration of P. anserina metabolism and development on biomass.
