PLOS Biol. This article describes a stochastic mathematical model of the stomatal closure network responding to abscisic acid (ABA). The Boolean network is constructed from a comprehensive literature review of the components’ dependencies. The model’s predictions agree with experimental data 90%…

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…

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,…

Proc. Natl Acad. Sci. USA. Xanthophylls zeaxanthin and lutein are involved in the nonphotochemical quenching (NPQ) pathway which is triggered in response to excess photons. The roles of zeaxanthin and lutein in NPQ are studied using mathematical models and Arabidopsis mutants. The authors hope that future…

This week's papers were seleted by Renee Dale. Renee is a PhD student in biology and an MS student in statistics at Loiusiana State University who is studying mathematical biology and biostatistics for plant biology applications. She is also working on an educational video game! Renee selected these…

By Stephan Wagner, Olivier Van Aken, Marlene Elsässer, Markus Schwarzländer Abstract Cells of complex organisms typically rely on mitochondria for energy provision. The amount of energy required to sustain cellular activity can vary strongly depending on external conditions. Vice versa, constraints…

By Bernhard Wurzinger, Ella Nukarinen, Thomas Nägele, Wolfram Weckwerth, Markus Teige Abstract The evolutionary conserved SnRK1 kinase complex is a key regulator in adjusting cellular metabolism during starvation, stress conditions and growth promoting conditions. Over the last two decades extensive…
