Gene Regulatory Networks (GRNs) are a useful tool for biologists to understand
the interactions among genes in living organisms. A special kind of GRNs known
as Logic Networks (LNs) has been recently introduced. These networks consider that
the state of one or more genes can in
uence another one. In a previous work, we proposed
a Membrane Computing model which simulates the dynamics of LNs by drawing
on the improved LAPP algorithm. In this paper we provide a case study for our LN
model on a network which regulates the circadian rhythms of long{term studied plant
Arabidopsis thaliana. We outline the software tools employed and propose a methodology
for analysing LNs on our Membrane Computing model. At the end of the paper, some
conclusions and future work are included.
