This model is termed P2011 and derives from the article: The clock gene circuit in Arabidopsis includes a repressilator with additional feedback loops. Alexandra Pokhilko, Aurora Piñas Fernández, Kieron D Edwards, Megan M Southern, Karen J Halliday & Andrew J Millar Mol. Syst. Biol. 2012; 8: 574, submitted 9 Aug 2011 and published 6 March 2012. Link Link to Supplementary Information, including equations. Minor errors in the published Supplementary Information are described in a file attached to version 1 of this model (the published SBML is correct). The model describes the circuit depicted in Fig. 1 of the paper (GIF attached). It updates the Pokhilko et al. 2010 model (termed P2010), PLM_6, by including:
- the Evening Complex genes (ELF4, ELF3, LUX),
- light-regulated degradation of ELF3 by COP1,
- TOC1 as a repressor rather than an activator of LHY/CCA1.

Version 2 of the model includes the StepFunction. Note that we have not yet removed the original light function parameter names, they are now non-functional.

The SBML for this version uses the lightfunction (as in Mol Syst Biol 2012 paper) to represent the light-dark cycle. It is assigned to parameter name L, which is used in the model reactions.
However, the internal parameters of lightfunction have default Copasi ID's, parameter_1 to parameter_6, with names that match the publication (photperiod, etc.). A COPASI file for this model is also attached.
This model is equivalent to the published version, referred to as P2011.1.1 in our later paper (Flis et al. RSOB 2015).
