Explore"Plates inoculated with Col-0 seed were grown under the same photoperiod conditions to the plants to be analysed. Plant tissue was harvested, making aliquots of 0.4 gFW. MBP-NL3F10H protein was prepared by the method described by Urquiza-Garcia U. and Millar A.J. in Plant Methods 2019. and then quantified by the linearized Bradford assay protocol using both Bovine serum albumin BSA and Ovoalbumin as standards (Ernst & Zor 2010). Then aliquots spiked with purified enzyme to generate a curve with: 0, 1x10^2, 1x10^3, 1x10^4, 1x10^5 and 1x10^6 molecules per cell, assuming 25x10^6 cells/gFw in Col-0 (Flis et al. 2015). Absolute quantities of protein then were determined by log-transforming the intensity, performing a linear regression and inverting the linear model."

The dataset presents mathematical models of the gene regulatory network of the circadian clock, in the plant Arabidopsis thaliana. The work will be published as Urquiza-Garcia, Molina, Halliday and Millar, title "Abundant clock proteins point to missing molecular regulation in the plant circadian clock", in Molecular Systems Biology, 2025.
Starting from the U2019.3 and U2020.3 models, this project rescales parameters to match protein levels that were predicted using a simple model from the TiMet ...

Insertion of events that rescued mutant phenotypes were selected for performing absolute quantification using calibration curves of recombinant purified MBP-NanoLUC-3Flag-10his. Seeds were sterilised with 5% houshold bleach for 10 min and washed three time with deionised water. The seeds were then put for stratifyication at 4ºC in darkenss for 48 hours in 1.5 ml polyproplyen tubes in dionised water. After 48 hours seeds wered plated on ROBUST agar (1/2 MS salts, 1.2% Agar pH 5.8 ajudsted with ...
