论文摘要
基于顶端生长和菌丝分支，这两个主要过程驱动了真菌网络的生长模式，我们在这里提出了基于二进制树建模的二维模拟，使我们能够提取通用thallus生长的主要特征。特别是，我们表明，在均匀的环境中，可以优化真菌生长，以探索和开发其周围环境，并具有顶端分支的特定角度分布。提取角度值的两种互补方法已被用来与从腐生丝状真菌podospora anserina的tallus生长获得的实验数据对抗的结果。最后，我们在这里提出了一个经过验证的模型，尽管计算低成本，但足以快速测试多个条件和约束。除了实验室实验之外，它将允许将来的工作加深真菌网络增长动态的表征，这有时可能是昂贵，乏味或有限的范围。
Based upon apical growth and hyphal branching, the two main processes that drive the growth pattern of a fungal network, we propose here a two-dimensions simulation based on a binary-tree modelling allowing us to extract the main characteristics of a generic thallus growth. In particular, we showed that, in a homogeneous environment, the fungal growth can be optimized for exploration and exploitation of its surroundings with a specific angular distribution of apical branching. Two complementary methods of extracting angle values have been used to confront the result of the simulation with experimental data obtained from the thallus growth of the saprophytic filamentous fungus Podospora anserina. Finally, we propose here a validated model that, while being computationally low-cost, is powerful enough to test quickly multiple conditions and constraints. It will allow in future works to deepen the characterization of the growth dynamic of fungal network, in addition to laboratory experiments, that could be sometimes expensive, tedious or of limited scope.
