Phenotypic diversity and chaos in a minimal cell model

Area of Science:

• Systems biology
• Origin of life research
• Theoretical biology

Background:

• Gánti's chemoton model is a foundational concept for minimal protocells.
• It comprises three essential subsystems: membrane, metabolism, and information.
• Stoichiometrical coupling links these subsystems, enabling a replication cycle.

Purpose of the Study:

• To explore the dynamical behaviors of a specific implementation of the chemoton model.
• To identify and characterize the range of complex dynamics, including chaotic patterns.
• To discuss the implications for understanding early cellular evolution and designing artificial cells.

Main Methods:

• Detailed computational exploration of a chemoton-like model.
• Analysis of dynamical patterns ranging from regular oscillations to chaotic regimes.
• Investigating the role of stoichiometrical coupling in system dynamics.

Main Results:

• The studied chemoton model displays a rich variety of dynamical patterns.
• Complex behaviors, including chaotic dynamics, were observed.
• The findings highlight the potential for diverse behaviors in minimal protocell models.

Conclusions:

• The chemoton model, implemented computationally, can exhibit complex and varied dynamics.
• These findings offer insights into the potential behaviors of early protocells.
• The results are relevant for the synthetic biology approach to creating artificial cells.
