Follow-up to the validation experiments on FMv2, testing candidate mechanisms for high malate and fumarate accumulation in the Arabidopsis double mutant prr7prr9 and its parent accession Col. New collaborations with the groups of Teresa Fitzpatrick and TiMet partner Samuel Zeeman.

Assorted files prepared during the publication process of the FMv2, its validation and testing, mostly focussed on the Arabidopsis double mutant prr7prr9 and its parent accession Col. Data from other studies that are described separately, and linked by Atribution to the File records under this Study.

Collection of models used in the introduction of absolute units into A. thaliana circadian clock models, with software resources and documentation. The models are inspired by P2011, published in Pokhilko et al 2012. The study contains Assays that link to the P2011 starting model and the models U2019.1 - .3 and U2020.1 - .3. Each model is shared as a human-readable file in the Antimony language and the associated, machine-readable SBML file, which was automatically generated using the SBML export ...

The P2011 model (linked in the Assay below) was rescaled to match TiMet RNA data in clock mutants from Flis et al. 2015, also linked here as separate mean and SD files. The raw TiMet data is available elsewhere on FAIRDOMHub.

Assays for model composition here, in order to share model files; potentially training and validation data in other Studies.

The models in this record were published in Flis et al. Royal Society Open Biology 2015. Their original IDs in the PlaSMo resource and IDs in Biomodels are given below. Please select files for download from the 'Related Items' list or the object tree/graph, below. 'SUBMITTED' is the original model version; 'SIMPLIFIED' removes SBML elements that were incompatible with SloppyCell software.

Photothermal model for Arabidopsis development, as published, converted to Simile format by Yin-Hoon Chew. Note that the XML file is just a dummy SBML file, the .SML is the working model file. Simile can read csv files (as attached) for meteorological data (hourly temperature, sunrise, sunset). Users only need to change the directory of the input variables. I have also attached the set of parameter values for each genotype.Related PublicationsWilczek et al. (2009). Effects of Genetic Perturbation ...

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., ...

Andrew's work-in-progress P2012 version. NB KNOWN PROBLEMS do not use lightly. Derived from PLM_49, after removing ABA regulation and tidying up the SBML in COPASI. Please see version comments for IMPORTANT notes.

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 ...

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 ...
