The model shows how the CONSTANS gene and protein in Arabidopsis thaliana forms a day-length sensor. It corresponds to Model 3 in the publication of Salazar et al. 2009. Matlab versions of all the models in the paper are attached to this record as a ZIP archive, as are all the data waveforms curated from the literature to constrain the model. Further information may be available via links from the authors web site (www.amillar.org). Simulation notes for SBML version of Model3 from Salazar et al., ...

Draft of MEP pathway for isoprenoid synthesis, created 2012-2013 by Oender Kartal in the Gruissem lab. He notes "It contains some annotations and references for the parameter values and rate equations and produces a stable steady state, so you can do some control analysis. It simulates day-metabolism, since the MEP Pathway is supposedly active during the day." Unpublished, for use by TiMet consortium only.

A cell-level model of the Arabidopsis root elongation zone. This spatial model is divided up into biological cells which are further divided into simulation boxes. The original model was designed to investigate how canal cells can accumulate auxin over time rather than to investigate the transport of auxin through the canal cells per se. The main outputs of the simulations in the original paper were the steady state ratios of auxin in the canal cell protoplasts to that in the parenchyma cell ...

Andrew's "ongoing work" record for the P2011 clock model. Many different versions, with annotations made during SBSI development in 2011-2013 - see version records.Version Comments Derived from PLM_67v3 - LDLL transition at 314h, with wider parameter ranges, as used in LDLL_run2 - but with one modification in Copasi, to cL_m degradation to ensure light rate > dark rate. Value of m1 previously 0.54, now 0.3. Simulation in Copasi was identical.

Andrew's "ongoing work" record for the P2011 clock model. Many different versions, with annotations made during SBSI development in 2011-2013 - see version records.Version Comments PLM_67v3 model, with TWO stepfunctions. Simulates fine but as of 21 March 2013 did not optimise.

Step2 is usually off because amplitude=0, but can produce LD-DD transition at 262h. To do so, initiate with amplitudeStep1=0 and amplitudeStep2=1.

NB the step1 will still go to LL at 314h, so need to stop DD costing before ...

PLM_67v2 set up for LDLL transition at 314h, with wider parameter ranges for most parameters. This is the model file used in LDLL_run2.

Many different versions, with annotations made during SBSI development in 2011-2013 - see version records.Version Comments Version 2 is the 'public' version with the StepFunction, PLM_64v4. For some reason this was crashing SBSI, but was then cleaned up by passing through Copasi. Thus the file name of this version was Arabidopsis_clock_P2011_exCopasi.xml

This version should be suitable for SBSI optimisation to LD-LL data sets, because it ...

P2011 model from PLM_43 version 6, optimised by Andrew Millar with SBSI PGA optimisation. A limited parameter set were free to optimise over < 10-fold range (less for RNA degradation rates), against ROBuST RNA data for clock genes in WT and mutants at 17C in LD, and period data in the same mutants in LL. The full SBSI costing is included, using costs from mid-June 2012 (note that costs returned with original optimisation in May were incorrectly reported).Originally submitted to PLaSMo on ...
