Signal transduction underlies how living organisms detect and respond to stimuli. A goal of synthetic biology is to rewire natural signal transduction systems. Bacteria, yeast, and plants sense environmental aspects through conserved histidine kinase (HK) signal transduction systems. HK protein components are typically comprised of multiple, relatively modular, and conserved domains. Phosphate transfer between these components may exhibit considerable cross talk between the otherwise apparently…

Programmable Ligand Detection System in Plants through a Synthetic Signal Transduction Pathway
TLDR
This work describes assembly and function of a complete synthetic signal transduction pathway in plants that links input from computationally re-designed periplasmic binding proteins to a visual response and may allow plants to serve as a simple and inexpensive means to monitor human surroundings for substances such as pollutants, explosives, or chemical agents.
Transplantation of prokaryotic two-component signaling pathways into mammalian cells
TLDR
It is found that coexpression of HKs and their cognate RRs in cultured mammalian cells is necessary and sufficient to strongly induce gene expression even in the absence of pathways’ chemical triggers in the medium, and their components can be used for large-scale synthetic gene circuits.
Crosstalk between endogenous and synthetic components – synthetic signaling meets endogenous components
TLDR
In this review, the design and function of two partially synthetic signaling pathways for use in plants is discussed and observed interactions (crosstalk) with endogenous signaling components are described.

Engineering Signal Transduction Pathways
Synthetic gene networks in plant systems.
TLDR
This chapter gives an overview of the existing plant genetic networks and describes in detail the application of two systems for inducible gene expression, the ethanol-inducible system and the dexamethasone-dependent nuclear translocation of the GOI::GR protein.
Synthetic biology of cell signaling
TLDR
While creating synthetic signaling cascades is perhaps one of the most challenging tasks in synthetic biology, potential implications can be far-reaching and include new tools for programming cells and tissues, artificial developmental processes, and therapeutic tools.
Strategies for protein synthetic biology
TLDR
An engineering framework is outlined for the connection of reusable protein interaction devices into self-sufficient circuits to ‘refacture’ protein complexity into well-defined exchangeable devices for predictive engineering.

Specificity in two-component signal transduction pathways.
TLDR
The cellular and molecular mechanisms that dictate the specificity of two-component signaling pathways are reviewed, including the role of phosphoryl group transfer, which can then effect changes in cellular physiology, often by regulating gene expression.
Evolution of two-component signal transduction.
TLDR
The structural and functional similarity between TCST kinases and eukaryotic protein kinases raises the possibility of a distant evolutionary relationship.
Fungal Histidine Kinases
TLDR
Because some phosphorelay proteins are essential for virulence of microbial pathogens, including the yeast fungus Candida albicans, novel antibiotics targeted to phosphorelays may be effective against eukaryotic pathogens without causing host cell damage.
Histidine protein kinases: key signal transducers outside the animal kingdom
TLDR
A large family of signal-transduction enzymes that autophosphorylate on a conserved histidine residue are found, which are important for multiple functions in bacteria, including chemotaxis and quorum sensing, and in eukaryotes, including hormone-dependent developmental processes.
Ethylene signal transduction.
TLDR
Data indicate that the site of ethylene perception is at the endoplasmic reticulum and point to the importance of protein complexes in mediating the initial steps in ethylene signal transduction.

TLDR
In this review, recent progress with regard to studies on TCS in higher plants will be discussed, focusing particularly on the model higher plant Arabidopsis thaliana.

Identification of CRE1 as a cytokinin receptor from Arabidopsis
TLDR
Evidence is provided that cytokinins can activate CRE1 to initiate phosphorelay signalling, and this work identifies Arabidopsis cre1 (cytokinin response 1) mutants, which exhibited reduced responses to cytokinin responses.

TLDR
This review summarizes the present knowledge about the principles and functions of two-component systems in higher plants and addresses several critical points with respect to cross talk, signal integration and specificity.
