Diffusiophoresis-enhanced Turing patterns. [PDF]

open access: yesSci Adv, 2023
Turing patterns are fundamental in biophysics, emerging from short-range activation and long-range inhibition processes. However, their paradigm is based on diffusive transport processes that yield patterns with shallower gradients than those observed in nature. A complete physical description of this discrepancy remains unknown.

Turing patterns with cellular computers. [PDF]

open access: yesCell Syst
Turing patterns are a key theoretical foundation for understanding organ development and organization. While they have been found to occur in natural systems, implementing new biological systems that form Turing patterns has remained challenging. To address this, Tica et al.1 used synthetic genetic networks to engineer living cellular computers that ...

Turing patterns inside cells. [PDF]

open access: yesPLoS ONE, 2007
Concentration gradients inside cells are involved in key processes such as cell division and morphogenesis. Here we show that a model of the enzymatic step catalized by phosphofructokinase (PFK), a step which is responsible for the appearance of ...

Turing and Non-Turing patterns in diffusive plankton model [PDF]

open access: yesComputational Ecology and Software, 2015
In this paper, we investigate a Rosenzweig-McAurthur model and its variant for phytoplankton, zooplankton and fish population dynamics with Holling type II and III functional responses.

Physical interactions in non-ideal fluids promote Turing patterns. [PDF]

open access: yesJ R Soc Interface, 2023
Turing's mechanism is often invoked to explain periodic patterns in nature, although direct experimental support is scarce. Turing patterns form in reaction-diffusion systems when the activating species diffuse much slower than the inhibiting species ...

Optimal network sizes for most robust Turing patterns [PDF]

open access: yesScientific Reports
Many cellular patterns exhibit a reaction-diffusion component, suggesting that Turing instability may contribute to pattern formation. However, biological gene-regulatory pathways are more complex than simple Turing activator-inhibitor models and ...

Turing pattern with proportion preservation [PDF]

open access: yesJournal of Theoretical Biology, 2006
Although Turing pattern is one of the most universal mechanisms for pattern formation, in its standard model the number of stripes changes with the system size, since the wavelength of the pattern is invariant: It fails to preserve the proportionality of the pattern, i.e., the ratio of the wavelength to the size, that is often required in biological ...

Widespread biochemical reaction networks enable Turing patterns without imposed feedback [PDF]

open access: yesNature Communications
Understanding self-organized pattern formation is fundamental to biology. In 1952, Alan Turing proposed a pattern-enabling mechanism in reaction-diffusion systems containing chemical species later conceptualized as activators and inhibitors that are ...
