Data, FMv2 model and simulations for the Chew et al. 2017 paper (bioRxiv https://doi.org/10.1101/105437 ), updated in 2022, mostly on the prr7 prr9 double mutant, with controls in lsf1 and prr7 single mutants. This is one of the outputs from the EU FP7 TiMet project, https://fairdomhub.org/projects/92.

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.
In this study, 14CO2 labelling was used to test the rate of carbon assimilation in the dark at the end of the subjective night (starting about ZT21), which is indicative of PEPC activity in forming malate, and the subsequent partitioning of this labelled C into various cellular fractions. The short-period ...

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.
In this study, thiamine vitamers were quantified to test whether the essential cofactor TDP had altered enzyme activities to affect the malate and fumarate levels, using existing plant samples harvested from am earlier L&H study.

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.
