From feedbacks to functional teams in the rhizosphere.

Area of Science:

• Plant-microbiome ecology
• Microbial ecology
• Evolutionary biology

Background:

• Plant-microbiome interactions are crucial for plant adaptation and ecosystem function.
• Understanding the drivers of microbial community assembly in planta is a key challenge.
• Existing frameworks do not fully integrate ecological and evolutionary processes.

Purpose of the Study:

• Introduce Functional Team Selection (FTS) as a novel conceptual advance.
• Explain the mechanisms by which FTS operates in plant-microbiome systems.
• Provide a framework for predicting the emergence of resilient plant-microbiome partnerships.

Main Methods:

• Conceptual synthesis of ecological feedback and evolutionary selection.
• Theoretical integration of resource limitation and stress as selective pressures.
• Development of a predictive framework for plant-microbiome co-adaptation.

Main Results:

• Functional Team Selection (FTS) posits that limiting resources and/or stress select for cooperative microbial teams.
• These cooperative teams enhance plant adaptation and resilience.
• FTS integrates ecological feedback loops with evolutionary selection pressures.

Conclusions:

• FTS offers a powerful new lens for understanding plant-microbiome dynamics.
• This framework advances our ability to predict the conditions favoring stable and beneficial plant-microbiome partnerships.
• The study highlights the importance of considering microbial cooperation in plant adaptation.
