Table 2 List of the different models, their variation compared to the previous model, and the outcome or idea for the next model

From: Mathematical modeling of diurnal patterns of carbon allocation to shoot and root in Arabidopsis thaliana

Model no.

Variation compared to previous model

Features/limitations

Required improvements

01

Basic model

Strong HP deflection at day/night transition

Better map day/night transition

02

Adjusted starch synthesis and degradation (r3 and r4)

Sharp deviance of CaAa pool at day/night transition

Introduce a constant respiration rate

03

Constant respiration rate during day and night

 

Split carbon pools to converge closer to the in vivo condition

04

Split carbon pool into a citrate and combined malate/fumarate pool

increased dynamics for Cit and MalFum

Interconversion of Cit and MalFum as in the TCA cycle

05

Interconversion between Cit and MalFum

Long simulation times (up to 8 h per simulation)

Splining of enzyme parameters to reduce simulation time

06

Splines for Vm values for sucrose cycling enzymes

Flat dynamics for Glc and Frc

Splining of selected enzyme parameters

07

Spline for SPS and Inv

Shorter simulation times (up to 4 h per simulation)

Exact distribution of excess carbon to shoot or root

08

Implementing the calculated SC gain

Final model
