Gene regulatory network (GRN) model underlying cell fate determination during Arabidopsis thaliana floral organ determination during early flower development.

<p>(A) GRN with interactions inferred from experimental data (according to <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0013523#pone.0013523-EspinosaSoto1" target="_blank">[4]</a>, <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0013523#pone.0013523-Chaos1" target="_blank">[8]</a>). The genes from the ABC model are highlighted in the GRN: A-genes (red), B-genes (yellow) and C-genes (blue). (B) Attractors or steady state gene configurations of the GRN model that match gene expression profiles expected by the ABC model are provided. Expressed genes for each attractor are represented as grey circles, while non-expressed ones correspond to white circles, the black circle corresponds to a gene (UFO) that can be either expressed or not expressed in the petal and stamen attractors, thus yielding two attractors for each petal and stamen primordia cell-type (taken from Ref. <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0013523#pone.0013523-AlvarezBullya1" target="_blank">[9]</a>).
