Sucrose translocation between plant tissues is crucial for growth, development and reproduction of plants. Systemic analysis of this metabolic process and underlying regulatory processes can help to achieve better understanding of carbon distribution within the plant and the formation of phenotypic traits. Sucrose translocation from ‘source’ tissues (e.g. mesophyll) to ‘sink’ tissues (e.g. root) is tightly bound to the proton gradient across the membranes. The plant sucrose transporters are grouped into efflux exporters (SWEET family) and proton-symport importers (SUC, STP families). To better understand the regulatory connections between sucrose export from source tissues and sucrose import into sink tissues, there is a need for a metabolic model that takes in account the tissue organisation of Arabidopsis thaliana with corresponding metabolic specificities of respective tissues in terms of sucrose and proton production/utilization. An ability of the model to operate under different light modes (‘light’ and ‘dark’) and correspondingly in different energy producing modes is additional validating feature.

I've become a SysMO DB PAL for MOSES project in 2007 being a post-doc in lab of Prof. Matthias Reuss at University of Stuttgart. In the MOSES project, our major efforts were in the experimental data acquisition for dynamic model of primary carbon and anaerobic energy metabolism in yeast. The model implements prediction of perturbations of two types: glucose pulse and temperature jump. We implement “stimulus-response” methodology for the unraveling the dynamic structure of the network and to ...

we describe a multi-compartmental model consisting of a mesophyll cell with plastid and mitochondrion, a phloem cell, as well as a root cell with mitochondrion. In this model, the phloem was considered as a non-growing transport compartment, the mesophyll compartment was considered as both autotrophic (growing on CO2 under light) and heterotrophic (growing on starch in darkness), and the root was always considered as heterotrophic tissue completely dependent on sucrose supply from the mesophyll ...

The multi-compartmental metabolic network of Arabidopsis thaliana was reconstructed and optimized in order to explain growth stoichiometry of the plant both in light and in dark conditions. Balances and turnover of energy (ATP/ADP) and redox (NAD(P)H/NAD(P)) metabolites as well as proton in different compartments were estimated. The model showed that in light conditions, the plastid ATP balance depended on the relationship between fluxes through photorespiration and photosynthesis including both ...

The solution of Flux Balance Analysis (FBA) represents metabolic flux distribution in ZucAt model under light growth conditions. In this solution, (i) the ratio photorespiration / photosynthesis has been fixed to 0.25; and (ii) cyclic electron flow through FQR (ferredoxin-plastoquinone reductase) has been set 0.1 from non-cyclic flow through FRN (ferredoxin-NADP oxidoreductase). Under this constraints, ATP formed by non-cyclic photophosphorylation is not sufficient to fulfill ATP/NADPH ratio for ...

The solution of Flux Balance Analysis (FBA) represents metabolic flux distribution in the model under light growth conditions. In this solution, (i) the photorespiration was set to 0; and (ii) cyclic electron flow through FQR (ferredoxin-plastoquinone reductase) has been set of 0.1 of flow through FRN (ferredoxin-NADP oxidoreductase). Under this constraints, ATP is under-produced in plastid and therefore is additionally imported to cytoplasm. Flux through FQR represents cyclic electron flow through ...

The solution of Flux Balance Analysis (FBA) represents metabolic flux distribution in ZucAt model under light growth conditions. In this solution, (i) the ratio photorespiration / photosynthesis has been fixed to 0.25; (ii) and ATP transport between plastid and cytoplasm has been set to 0. The last constraint allows finding the ratio between fluxes through FQR (ferredoxin-plastoquinone reductase) and FRN (ferredoxin-NADP oxidoreductase) under which the ATP balance in plastid becomes self-sufficient ...

The model presents a multi-compartmental (mesophyll, phloem and root) metabolic model of growing Arabidopsis thaliana. The flux balance analysis (FBA) of the model quantifies: sugar metabolism, central carbon and nitrogen metabolism, energy and redox metabolism, proton turnover, sucrose translocation from mesophyll to root and biomass growth under both dark- and light-growth conditions with corresponding growth either on starch (in darkness) or on CO2 (under light). The FBA predicts that ...
