Standard growth conditions and standard 'wild-type' Arabidopsis accession, with biomass data for whole rosettes, and in some cases, individual leaf area and leaf biomass data

Standard growth conditions and 'wild-type' Arabidopsis accessions other than Col-0 and the 35S:miR156 transgenics, with biomass data for whole rosettes, and in some cases, individual leaf area and leaf biomass data

The FMv1 was constructed from 4 existing models, with Matlab and Simile versions.

Combination of multiple sub-models to form Framework Model version 2

Biomass, leaf number and metabolites in Col0 (WT), prr7, prr7prr9, and lsf1. Metabolite data from plants after 28 days of growth were analysed most (27 days 'end of night', 28 days 'end of day' and 'end of night'). The data file also includes data from 21 days of growth ('end of day' and 'end of night'), which is useful for comparison to early-flowering plants not tested here, such as the lhycca1 double mutant, that flower before 28 days, altering their physiology.

Biomass (fresh mass, dry mass), leaf numbers, leaf area, gas exchange and 12 metabolites in Col0 (WT), prr7prr9, and lsf1 (presented in the preprint/paper) and pgm (not analysed further).

Biomass (fresh mass, dry mass), leaf numbers, leaf area, gas exchange and 12 metabolites in Col0 (WT), prr7prr9, and pgm at days 29 and 35, presented in the preprint/publication, with most data also for Col and lhycca1 at days 21/22/23, not analysed further.

We suggest that the lower carbon assimilation rate measured in lhycca1 (see gas exchange data) might allow a calibirated simulation in the FMv2 model in future to incorporate the indirect effects of nightly carbon starvation in this genotype ...

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 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 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 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 ...

Biomass, leaf number and gas exchange data for Col0 (WT), prr7prr9, and lsf1, compiled from four studies: L&H1-3 and the 'no GA' controls of Gibberellins 1.

Excel spreadsheet with data and simulations used to prepare figures for publication, see Metadata sheet for conditions. Data Fresh (not dry) rosette leaf biomass, measured in samples of 5 plants each on multiple days, as mean and SD; Simulation outputs from FMv2 for Col Wild Type plants, and two simulations for prr7prr9 where the mutation affects only starch degradation or both starch degradation and malate/fumarate store mobilisation.

Excel workbook with included Read.Me sheet, including FW and DW biomass data derived from files linked elsewhere; a compilation of the rosette area and gas exchange data for every plant measured of the Col, lsf1 and prr7prr9 genotypes; statistical analysis across the experiments; and charts of the compiled data, some of which are presented as figure panels in the 2022 versions.

Biomass data for individual plants at day 35, fresh and dry weights, as well as mean and SD, from study Gibberellins 1

Excel sheet with mean and SD biomass data and charts, individual metabolite replicates, mean, SD and charts Details on Read.ME worksheet

Excel file with data on levels of thiamine and its metabolites TMP and active cofactor TDP, tested in Col and prr7prr9 samples from study Laurel and Hardy 3. Altered levels of TDP could potentially affect enzymes with TDP cofactors that metabolise malate and fumarate levels, altering their levels in prr7prr9.

Excel spreadsheets for biomass, leaf number, gas exchange and metabolites, including pgm and lhycca1. Key data are for 27-28 day old plants for Col and prr7prr9, analysed for the preprint/publication. Gas exchange data for lhycca1 showed lower Assimilation per unit area than Col, prr7prr9; A in pgm was higher than Col. Metabolite data were also collected for Col and lhycca1 at 18 days, before the lhycca1 flowered, but these are marked as unreliable.

Complete excel spradsheets for Laurel and Hardy 2, including data for the pgm mutant that were not analysed in the Chew et al. 2017 preprint/publication. Data include fresh and dry biomass, gas exchange, leaf numbers and metabolites in Col0 (WT), prr7prr9, pgm and lsf1 plants. Metabolite data are from plants after 27 days of growth (end of night) and 28 days (end of day and end of night).
