New framework explains the gap between plant potential and plant action
Plant Signaling
The fungal threads tangled around your garden plants' roots aren't just passive helpers, they're part of a filtering system that decides in real time which of a plant's many possible responses actually get expressed.
Think of a plant like someone with a long list of things they could theoretically do, but only some of those options are actually available given the situation they're in right now. This paper argues that the relationship between a plant and its fungal partners in the soil (called the mycorrhizosphere) narrows down that list, and it proposes a new step in the plant's decision-making process to describe how that narrowing happens. It's part of a series building a bigger theory of how plants sense, interpret, and eventually act on their world.
Key Findings
Introduces 'Behavioral Potential' as a new conceptual layer sitting between a plant's underlying Capacity (what it could support) and its observable Response (what it actually does)
Uses mycorrhizal fungus-root relationships as a case study to show how internal and external constraints limit which theoretically possible behaviors a plant can actually realize
Presents the 'General Behavior Event-Drift Sequence,' a unified model chaining Signal, Perception, Interpretation, Behavioral Potential, and Response, plus a proposed future 'Drift Phase' linking outcomes back to future conditions
chevron_right Technical Summary
This paper proposes a new theoretical framework for how plants 'decide' among possible responses, arguing that even when a plant has the biological capacity to do something, actual conditions (like its relationship with soil fungi) determine which of those possibilities it can realistically act on.

Mycorrhizal networks are underground fungal systems that connect plant roots together, forming symbiotic relationships where fungi provide essential nutrients and water in exchange for sugars produced by photosynthesis. These networks fundamentally reshape how plants acquire resources and interact
