Data, models and simulations for the Chew et al. 2014 paper (PNAS, https://doi.org/10.1073/pnas.1410238111), using wild-type Arabidopsis ecotype Col-0 in standard 12hL:12hD growth conditions, compared to La(er) or Fei-0 accessions, or to plants overexpressing a micro RNA (miR156).

Data, models and simulations for the Chew et al. 2017 paper (bioRxiv https://doi.org/10.1101/105437 ), mostly on the prr7 prr9 double mutant, with controls in lsf1 and prr7 single mutants.

Data for Figure 2I-2K in Chew et al. PNAS 2014.
Experimental conditions: ∼21.3 °C; 12:12-h light/dark cycle; light intensity, 110 μmol·m−2·s−1;mean daytime CO2 level, 375 ppm. The error bars show the SEs of five plants
Further detail on the experimental conditions is contained in the public record on the BioDare resource, link to follow

Data for Figure 3G and Supplementary Figure 4, including gas exchange measurements and photo of the experimental setup. The 'Summary' sheets in the XLSX files often include published graphs. Simulation data are included from FMv1.

These data were acquired in a separate experiment from the biomass, in March 2013. Replication of the earlier biomass study was imperfect, as some plants became a little dry when watering was controlled to reduce moss growth. Sufficient plants grew strongly to measure

Data for Figure 3A-3F and Supplementary Figures 2, 3, and 6, including leaf number, biomass and leaf areas. Image data for leaf areas are included in a .ZIP archive. The 'Summary' sheets in the XLSX files often include published graphs. Simulation data are included from FMv1.
These data were acquired in June 2012.
Experimental conditions: ~22C constant temperature; 12:12-h light/dark cycle; light intensity = 130 μmol·m−2·s−1; average daytime CO2 concentration = 375 ppm. 10 plants per genotype per

Data for Figures 5D-5F and Supplementary Figure 7B, 7C, including biomass and leaf areas. Image data for leaf areas are included in a .ZIP archive, with two samples as published in 5D. The 'Summary' sheets in the XLSX files include published graphs. Simulation data are included from FMv1.
These data were acquired in April 2014, in a separate experiment from the La(er) and Fei-0.
Experimental conditions: ∼20.7 °C constant temperature; 12h:12h light/dark cycle; light intensity = 100μmol·m−2·s−1;

In future we should split these versions into separate Assays, and link to the four, original component models, when they are imported with the PlaSMo resource into FairdomHub (expected late 2018)

Data for Figure 4, from the prior publication of Sulpice et al. Mol. Plant 2014: Biomass, net growth and starch levels at end of day and end of night, under light:dark cycles of 4:20, 6:18, 8:16, 12:12 and 18:6 hours.

These Python scripts define and simulate the translational coincidence model. This model takes measured transcript dynamics (Blasing et al, 2005) in 12L:12D, measured synthesis rates of protein in light compared to dark (Pal et al, 2013), and outputs predicted changes in protein abundance between short (6h) and long (18h) photoperiods. These are compared to the photoperiod proteomics dataset we generated.

Intact rosette is pictured, with plant number and genotype in handwritten labels, and ruler for scale.
Then dissected leaves are organised in sequence of age, if necessary with small cuts to let them lie flat.
Areas are then measured in image processing.

Data for Figs 3C, 3F and Supp 2 in Chew et al. PNAS 2014
Leaf number of the growing rosettes, from 4 to 37 days after sowing (DAS).
Data and also results of FMv1 model simulations.
Note that Fei-0 was previously tested by Mendez-Vigo et al, suggesting this line had a higher leaf appearance rate. We suggested that its larger final leaf number was more likely due to faster germination.

binary data file from "Hobo" environment multi-sensor + data logger, located next to the plants used in the experiment. Usually read in HOBOware software, free from Onsetcomp.com. Useful temperature record. Though light levels can usefully show changes they are not well calibrated.

This record includes Matlab and Simile format versions of the Arabidopsis Framework Model version 1, FMv1 (Chew et al, PNAS 2014; http://www.pnas.org/content/early/2014/08/27/1410238111), copied from the PlaSMo resource (www.plasmo.ed.ac.uk), PLM_ID=76. The model description is in the Supplementary Materials of the publication, which should be uploaded somewhere here also but I don't see how to do it.

The FMv1 links the following sub-models:

Framework Model for Arabidopsis vegetative growth, version 2 (FMv2), as described in Chew et al. bioRxiv 2017 (https://doi.org/10.1101/105437; please see linked Article file).

The FMv2 model record on FAIRDOMHub has the following versions, which represent the same FMv2 model:
Version 1 is an archive of the github repository of MATLAB code for the Framework Model v2, downloaded from https://github.com/danielseaton/frameworkmodel on 06/02/17. This version was not licensed for further use and was

Exactly the same as model 243, but uploaded as a file rather than copied from PlaSMo.

This version is P2011.1.2, model ID PLM_71 version 1. Dynamics identical to P2011.1.1 of the Pokhilko et al. 2012 publication.
