Model outputs mRNA expression of PIF4/5 that is under control of the Pokhilko extended circadian clock. The first version (Model 2a in the supplementary file) has inhibition of PIFs from TOC1. The second version (Model 2c) has PIF activity promoted by LHY/CCA1 - this is currently the most accurate model when compared to data. Models shall be updated later to include PIF4/5 protein levels. Parameter values for this and other External Coincidence models found in supplementary file.Version Comments ...

DALEC (Data Assimilation Linked Ecosystem Carbon) represents the C cycle with a simple box model of pools connected via fluxes. There are five pools: C content of foliage (Cf); woody stems and coarse roots (Cw) and fine roots (Cr); and of fresh leaf and fine root litter (Clitter) and soil organic matter (SOM) plus WD (CSOM/WD).  The fluxes among pools are based on the following assumptions: All C fixed during a day is either expended in autotrophic respiration or else allocated to one of three ...

"The CENTURY model is a general model of plant-soil nutrient cycling which is being used to simulate carbon and nutrient dynamics for different types of ecosystems including grasslands, agricultural lands, forests and savannas.  CENTURY is composed of a soil organic matter/ decomposition submodel, a water budget model, a grassland/crop submodel, a forest production submodel, and management and events scheduling functions. It computes the flow of carbon, nitrogen, phosphorus, and sulfur through ...

This is the representation of major parts of the central metabolism in monocotyledon plants. The information has been derived from the MetaCrop [2] database, a manually curated repository of high quality information concerning the metabolism of crop plants. This includes pathways, reactions, locations, transport processes, and moreOriginally submitted to PLaSMo on 2012-03-05 11:52:18

The first version of the model corresponds to the one published in Pokhilko et al Mol Syst Biol 2010, which is also presented on the Mol. Syst. Biol. website and was submitted to the Biomodels database. Note: minor errors in published supplementary information are documented in a file attached to version 1; the published SBML files are correct. The second version has some names slightly modified for compatibility with the SBSI platform. Both first and second versions have values of  "dawn" fixed ...

Model of the arabidopsis circadian clock obtained from the Bio-PEPA model. The model is based on Alexandra Pokhilko's 2010 deterministic model and includes a scaling factor omega to translate from continuous "concentrations" to discrete amounts. Light function is a smooth function switching between 0 and 1, and is parameterised in order to allow to automate experimentation with different light conditions and photoperiods.Related PublicationsMaria Luisa Guerriero, Alexandra Pokhilko, Aurora Piñas ...

Validation. Validated against original implementation running under GNU FORTRAN 95. To allow the maximum flexiblity during validation the original FORTRAN code was modified slightly (note that no code lines were deleted). The code was run with high precision so that values were directly comparable with those in Simile even after hundreds of thousands of iterations. The values of all the variables in the original code were printed to the screen so that they could be checked against their Simile ...
