Modelling filamentous fungal growth — •Pascal Klamser¹, Carlos Aguilar-Trigueros² und Dirk Brockmann¹ — ¹Technische Universität Dresden, Dresden, Germany — ²University of Jyväskylä, Jyväskylä, Finland

The growth of a filament forming fungi is mesmerizing and a great example of an organism that forms a transport network and explores its environment for nutrients. While recent research shows how nutrients and other compounds are transported through the network, we will focus on a transport-agnostic model to explore the possible ways of how the tip of a filament can choose its growth direction. We assume a purely external communication via the diffusion of enzymes released by the filaments and can recreate a wide range of phenotypes. We compare it with experiments by estimating the hierarchical structure of the network from microscopic images.
