Probing the stochastic property of endoreduplication in cell size determination of Arabidopsis thaliana leaf epidermal tissue

, , ,
PLOS One. Endoreduplicated cells grow in size as their DNA content increases. The distribution of size was observed to be Poisson. This allowed the authors to create a mathematical model with a single parameter which describes the probability of exiting endoreduplication. The model recovers cell size…

Predicting gene regulatory networks by combining spatial and temporal gene expression data in Arabidopsis root stem cells

, , ,
Proc. Natl. Acad. Sci. USA. GENIST (gene regulatory network inference from spatiotemporal data) is a new algorithm developed by de Luis Balaguer et al to predict new gene interactions and transcriptional regulators (available at https://github.com/madeluis/GENIST). The algorithm combines inference of…

Adjustment of the Arabidopsis circadian oscillator by sugar signalling dictates the regulation of starch metabolism

, , ,
Sci Reports. Both starch degradation and accumulating sucrose levels are related to the circadian cycle, although it is unknown which is the primary regulator. The authors created a mathematical model wherein the circadian oscillator responds to sucrose. The model predictions were experimentally validated…

Modeling the metabolism of Arabidopsis thaliana: Application of network decomposition and network reduction in the context of Petri nets

, , ,
Front. Genetics. In this paper, the authors model the metabolism in Arabidopsis using Petri nets (PN). PNs are dynamic models that use “tokens” to represent movement between the places and edges of the model, representing the products of a reaction. The model was simplified using reduction techniques,…
