“…Moreover, it has been shown that the response of a fungus to a stress can also vary depending on whether it is a first confrontation or if the fungus has previously been able to adapt to a more or less similar stress. Also, the response to several combined stresses is not the simple sum of individual stress responses [ 33 , 39 ]. It is therefore interesting to consider in the future to approach more realistic environmental conditions.…”

“…Indeed, here, to simplify the analysis, and as a first intention, we have selected five constraints, applied separately and over the whole observation period. It could be interesting to extend our study to other abiotic stresses, which fungi are likely to encounter in their environment, such as variations in pH [20], or humidity [11], the presence of polluted water (toxic metals) or hydrophobic compounds [33]. Hyphae can also be subjected to mechanical constraints, such as obstacles in their pathways, or confinement in the pores of the growth substrate [34,35].…”

In their natural environment, fungi are subjected to a wide variety of environmental stresses which they must cope with by constantly adapting the architecture of their growing network. In this work, our objective was to finely characterize the thallus development of the filamentous fungus Podospora anserina subjected to different constraints that are simple to implement in vitro and that can be considered as relevant environmental stresses, such as a nutrient-poor environment or non-optimal temperatures. At the Petri dish scale, the observations showed that the fungal thallus is differentially affected (thallus diameter, mycelium aspect) according to the stresses but these observations remain qualitative. At the hyphal scale, we showed that the extraction of the usual quantities (i.e. apex, node, length) does not allow to distinguish the different thallus under stress, these quantities being globally affected by the application of a stress in comparison with a thallus having grown under optimal conditions. Thanks to an original geomatics-based approach based on the use of automatized Geographic Information System (GIS) tools, we were able to produce maps and metrics characterizing the growth dynamics of the networks and then to highlight some very different dynamics of network densification according to the applied stresses. The fungal thallus is then considered as a map and we are no longer interested in the quantity of material (hyphae) produced but in the empty spaces between the hyphae, the intra-thallus surfaces. This study contributes to a better understanding of how filamentous fungi adapt the growth and densification of their network to potentially adverse environmental changes.
