VirtualLeaf: an open-source framework for cell-based modeling of plant tissue growth and development.

Area of Science:

• Plant biology
• Computational biology
• Developmental biology

Background:

• Plant organ development involves complex interactions between gene regulation, cell division/expansion, and tissue mechanics.
• Traditional genetic approaches struggle to link genes directly to traits due to this complexity.
• Mathematical modeling offers insights but requires specialized skills, limiting accessibility for experimental biologists.

Purpose of the Study:

• Introduce VirtualLeaf, a cell-based computer modeling framework for plant tissue morphogenesis.
• Provide an accessible tool for experimental biologists to simulate and analyze plant development.
• Facilitate understanding of gene function within the biophysical context of growth and patterning.

Main Methods:

• Developed VirtualLeaf, a C++ framework with intuitive objects (cells, cell walls, chemicals).
• Created biologically relevant abstractions for building developmental simulations.
• Provided example models for leaf venation and meristem development.

Main Results:

• VirtualLeaf enables the creation of biologically intuitive simulations of plant tissue morphogenesis.
• The framework simplifies the analysis of gene function in developmental processes.
• Example models demonstrate the utility for studying leaf venation and meristem development.

Conclusions:

• VirtualLeaf offers a powerful, accessible platform for plant developmental research.
• It bridges the gap between experimental biology and computational modeling.
• The open-source framework supports analysis of gene function in the context of biophysics.
