OpenAlea

OpenAlea provides computational modeling and simulation of plant architecture and pathosystems using Functional-Structural Plant Models (FSPMs) to analyze plant–environment and plant–pathogen interactions for crop protection and trait optimization.

Key Features:

• Functional-Structural Plant Models (FSPMs): Implements FSPMs to simulate plant architecture and plant–environment interactions, including plant–pathogen dynamics.
• Conceptual pathosystem modeling: Formalizes entities and interactions within pathosystems into a conceptual model implemented in the framework.
• Generic data structures for lesions and dispersal units: Provides generic data structures to represent lesions and dispersal units.
• Canopy and microenvironment protocols: Defines protocols for interaction with canopy objects and their microenvironments.
• Library of elementary models: Includes a library of elementary models that can be combined to construct comprehensive pathosystem simulations.
• Multiscale modeling: Supports multiscaled interactions by composing models across scales.
• Model decomposition into knowledge sources: Enables decomposition of complex models into separate "knowledge sources" from diverse expertise areas.
• Simulation of architectural trait effects: Enables simulation studies such as assessing the impact of canopy architectural traits on fungal dispersal.

Scientific Applications:

• Plant architecture optimization and crop management: Use FSPMs to analyze and optimize architecture-related traits for crop management.
• Pathosystem simulation and analysis: Simulate plant–pathogen interactions, lesion development, and dispersal unit dynamics within canopies.
• Assessing fungal dispersal: Test the effects of canopy architecture on fungal dispersal.
• Multiscale and interdisciplinary modeling: Integrate models from diverse expertise to study interactions across scales.
• Informing crop protection strategies: Provide simulation-based insights to develop environmentally responsible crop protection strategies.

Methodology:

Formalize entities and interactions within pathosystems into a conceptual model; implement that framework to include plant–pathogen dynamics; create generic data structures for lesions and dispersal units; define protocols for interacting with canopy objects and microenvironments; provide a library of elementary models that can be combined for multiscale simulations.
