PLATINUM SENSITIVE 2 LIKE impacts growth, root morphology, seed set, and stress responses
Lillo, Catherine; Kataya, Amr R. A.; Creighton, Maria Terese; Napitupulu, Toga P.; Sætre, Christine; Heidari, Behzad; Ruoff, Peter (Journal article; Peer reviewed, 2017-07)Eukaryotic protein phosphatase 4 (PP4) is a PP2A-type protein phosphatase that is part of a conserved complex with regulatory factors PSY2 and PP4R2. Various lines of Arabidopsis thaliana with mutated PP4 subunit genes ... -
Semi-algebraic optimization of temperature compensation in a general switch-type negative feedback model of circadian clocks
Aase, Sven Ole; Ruoff, Peter (Journal article; Peer reviewed, 2008)Temperature compensation is an essential property of circadian oscillators which enables them to act as physiological clocks. We have analyzed the temperature compensating behavior of a generalized transcriptional–translational ... -
Sensitivity analysis of a pathway with respect to fast and small temperature change
Zakhartsev, Maksim; Ruoff, Peter (Journal article; Peer reviewed, 2019)Temperature affects all enzymes simultaneously in a metabolic system. The enzyme concentration in a biochemical system can be considered as invariant under fast and small temperature change. Therefore, the total sensitivity ... -
The organization of controller motifs leading to robust plant iron homeostasis
Agafonov, Oleg; Selstø, Christina Helen; Thorsen, Kristian; Xiang, Ming Xu; Drengstig, Tormod; Ruoff, Peter (Journal article; Peer reviewed, 2016-01)Iron is an essential element needed by all organisms for growth and development. Because iron becomes toxic at higher concentrations iron is under homeostatic control. Plants face also the problem that iron in the soil is ... -
Variable setpoint as a relaxing component in physiological control
Risvoll, Geir; Thorsen, Kristian; Ruoff, Peter; Drengstig, Tormod (Journal article; Peer reviewed, 2017-09)Setpoints in physiology have been a puzzle for decades, and especially the notion of fixed or variable setpoints have received much attention. In this paper, we show how previously presented homeostatic controller motifs, ...
