Protein control of photochemistry and transient intermediates in phytochromes
Phytochromes are ubiquitous photoreceptors responsible for sensing light in plants, fungi and bacteria. Their photoactivation is initiated by the...
-
Evidence for evolutionary relationship between archaeplastidal and cyanobacterial phytochromes based on their chromophore pockets
Phytochromes are photoreceptor proteins with a bilin chromophore that undergo photoconversion between two spectrally different forms, Pr and Pfr. In...

Improved fluorescent phytochromes for in situ imaging
Modern biology investigations on phytochromes as near-infrared fluorescent pigments pave the way for the development of new biosensors, as well as...

Role of guard cell- or mesophyll cell-localized phytochromes in stomatal responses to blue, red, and far-red light
Main conclusionGuard cell- or mesophyll cell-localized phytochromes do not have a predominant direct light sensory role in red- or...

Phytochromes transmit photoperiod information via the evening complex in Brachypodium
BackgroundDaylength is a key seasonal cue for animals and plants. In cereals, photoperiodic responses are a major adaptive trait, and alleles of...

Root growth in Orchid Dendrobium cv. Sonia requires shade avoidance response of phytochromes along with regulation of auxin pathway genes
Orchid Dendrobium Sonia has wide demand in floral market throughout the world due to its vibrant coloured flowers, flowering recurrence and dense...

Bacillus sp. LC390B from the Maize Rhizosphere Improves Plant Biomass, Root Elongation, and Branching and Requires the Phytochromes PHYA and PHYB for Phytostimulation
The plant microbiomes include root-associated beneficial species, which rely on carbon supplements to survive and exert their diverse attributes....

A LexA-based yeast two-hybrid system for studying light-switchable interactions of phytochromes with their interacting partners
Phytochromes are a family of photoreceptors in plants that perceive the red (R) and far-red (FR) components of their light environment. Phytochromes...

Correction to: Phytochromes
In the original version of this book, Chapter 9 was inadvertently published with few errors in Table 2 data. This has now been rectified in this...

Co-immunoprecipitation Assays to Detect In Vivo Association of Phytochromes with Their Interacting Partners
The red (R)/far-red (FR) light absorbing phytochromes are one of the major photoreceptor classes in plants. Phytochromes exist in two distinct but...
-
Measurement of Phytochrome B Thermal Reversion Rates In Vivo
Thermal reversion of phytochromes is the light-independent but strongly temperature-dependent relaxation of the light-activated Pfr form of...

Structural insights into photoactivation and signalling in plant phytochromes
Plant phytochromes are red/far-red photochromic photoreceptors that act as master regulators of development, controlling the expression of thousands...

Phytochromes and Cyanobacteriochromes: Photoreceptor Molecules Incorporating a Linear Tetrapyrrole Chromophore
In this chapter, we summarize the molecular mechanisms of the linear tetrapyrrole-binding photoreceptors, phytochromes, and cyanobacteriochromes. We...

Assessing the Function of CBF1 in Modulating the Interaction Between Phytochrome B and PIF4
Phytochromes are red (R) and far-red (FR) light photoreceptors in plants. Upon light exposure, photoactivated phytochromes translocate into the...

Structural mechanism of signal transduction in a phytochrome histidine kinase
Phytochrome proteins detect red/far-red light to guide the growth, motion, development and reproduction in plants, fungi, and bacteria. Bacterial...

Critical Factors Responsible for Potato Tuberization
The potato ( Solanum tuberosum ) is the fourth most cultivated and consumed crop worldwide. The swelled stolonic region of the plant is economically...

Dynamics and efficiency of photoswitching in biliverdin-binding phytochromes†
The light-driven conversions between the dark-adapted and the photoproduct state were recorded for bacteriophytochromes (BphP) carrying biliverdin...

Conserved histidine and tyrosine determine spectral responses through the water network in Deinococcus radiodurans phytochrome
Phytochromes are red light-sensing photoreceptor proteins that bind a bilin chromophore. Here, we investigate the role of a conserved histidine...

Influence of the PHY domain on the ms-photoconversion dynamics of a knotless phytochrome
The ability of some knotless phytochromes to photoconvert without the PHY domain allows evaluation of the distinct effect of the PHY domain on their...

Upregulation of GLRs expression by light in Arabidopsis leaves
BackgroundGlutamate receptor-like (GLR) channels are plant homologs of iGluRs, animal ionotropic glutamate receptors which participate in...
