A framework for utilizing leaf-associated microbes to achieve conservation and restoration goals

Area of Science:

• Ecology
• Microbiology
• Conservation Biology

Background:

• Plant-associated microbiomes significantly influence ecosystem functioning and plant success.
• Microbes are key components of healthy plants and ecosystems, vital for conservation and management.
• While root microbiome manipulation shows success, the leaf microbiome's role in conservation is largely unexplored.

Purpose of the Study:

• To emphasize the essential role of the leaf microbiome in plant and ecosystem health.
• To advocate for the inclusion of leaf microbiomes in conservation strategies.
• To propose a framework for managing leaf microbiomes in conservation efforts.

Main Methods:

• This perspective paper reviews existing knowledge and proposes a conceptual framework.
• The framework includes identifying disturbances, stress mechanisms, microbial inoculation strategies, and stakeholder engagement.
• It focuses on a proactive approach to leaf microbiome management.

Main Results:

• The leaf microbiome, like the root microbiome, is critical for plant health and ecosystem services.
• Current conservation strategies largely overlook the potential of leaf-associated microbes.
• A structured approach to leaf microbiome management is needed.

Conclusions:

• The leaf microbiome plays an essential role in plant and ecosystem health and must be considered in conservation.
• A framework is presented for managing leaf microbiomes, addressing disturbances and employing microbial interventions.
• Collaborative management plans involving stakeholders are crucial for successful conservation outcomes.
