Mathematical Modelling of Fungal Growth and Function

Summary

This research explores how mathematics can help us understand how fungi grow and function across different sizes – from microscopic to very large scales. Scientists used various mathematical tools to study how fungal networks develop, how materials move through them, and how they release spores. Impacts on everyday life: • Helps improve our understanding of how fungi decompose organic matter in nature • Could lead to better methods for controlling fungal growth in agriculture and medicine • Provides insights that could be useful for developing new biotechnology applications • Helps explain how fungi spread and colonize new environments • Could contribute to developing better antifungal treatments

Background

Mathematical modelling plays a crucial role in understanding hyphal networks’ growth and function. The main challenge is addressing scale, as fungal mycelia operate from submicron to kilometer ranges. Additional complexity comes from modeling physical and nutritional heterogeneity of host environments and the resulting sensing and response events that determine network architecture.

Objective

To showcase state-of-the-art mathematical and computational approaches to both scale-specific and cross-scale problems in modeling fungal physiology and function. The study aimed to demonstrate how interdisciplinary approaches can advance multi-scale understanding of fungal biology.

Results

The research demonstrated successful modeling of mycelial networks showing qualitative and quantitative agreement with experimental data. Growth-induced mass flows were found to correlate with cord thickness development. Stokes’ Law proved effective for modeling spore discharge across various fungi species. Complex multidirectional nuclear flows were observed several centimeters behind growing colony fronts, suggesting mechanisms for maximizing genetic diversity.

Conclusion

The interdisciplinary approaches presented significant advances in understanding fungal biology across multiple scales. The studies validated various mathematical models for different aspects of fungal growth and function, from network development to spore discharge mechanics. The research demonstrated the effectiveness of quantitative mathematical modeling in translating molecular genetics to organism-level understanding.
