Simulating oilseed fatty acid composition through a stochastic modelling approach

A simulation model was developed to study the accumulation dynamics of seed oil fatty acids (FAs) in response to environmental stimuli. The Petri Net (PN) formalism was used to encode a virtual analogue of the FA biosynthetic pathway, where the process is governed by rules targeting enzymatic regulatory mechanisms. Four alternative types of rules were conceived: i) constant enzymatic activity throughout seed development; ii) enzymatic activity...
