We study a cellular automaton (CA) model of information dynamics on a single hypha of a fungal mycelium. Such a filament is divided in compartments (here also called cells) by septa. These septa are invaginations of the cell wall and their pores allow for flow of cytoplasm between compartments and hyphae. The septal pores of the fungal phylum of the Ascomycota can be closed by organelles called Woronin bodies. Septal closure is increased when the septa become older and when exposed to stress conditions. Thus, Woronin bodies act as informational flow valves. The one dimensional fungal automata is a binary state ternary neighbourhood CA, where every compartment follows one of the elementary cellular automata (ECA) rules if its pores are open and either remains in state `0' (first species of fungal automata) or its previous state (second species of fungal automata) if its pores are closed. The Woronin bodies closing the pores are also governed by ECA rules. We analyse a structure of the composition space of cell-state transition and pore-state transitions rules, complexity of fungal automata with just few Woronin bodies, and exemplify several important local events in the automaton dynamics.

真菌自动机

我们在真菌菌丝体的单个菌丝上研究了信息动力学的元胞自动机 (CA) 模型。这样的细丝被隔膜分成隔室（这里也称为细胞）。这些隔膜是细胞壁的内陷，它们的孔允许细胞质在隔室和菌丝之间流动。子囊菌门真菌门的间隔孔可以被称为 Woronin 小体的细胞器关闭。当隔垫变老和暴露在压力条件下时，隔垫闭合会增加。因此，Woronin 机构充当信息流阀。一维真菌自动机是一个二元状态三元邻域 CA，其中每个隔间都遵循基本元胞自动机 (ECA) 规则之一，如果它的孔是开放的，或者保持在状态“0” （真菌自动机的第一种）或其先前状态（真菌自动机的第二种），如果它的孔是封闭的。关闭毛孔的 Woronin 机构也受 ECA 规则的约束。我们分析了细胞状态转换和孔状态转换规则的组成空间的结构，只有少数 Woronin 小体的真菌自动机的复杂性，并举例说明了自动机动力学中的几个重要局部事件。
