Red and far-red light–sensing phytochromes are widespread in nature, occurring in plants,
algae, fungi, and prokaryotes. Despite at least a billion years of evolution, their photosensory …

Phytochromes are ubiquitous photosensor proteins, which control the growth, reproduction
and movement in plants, fungi and bacteria. Phytochromes switch between two …

Phytochrome photoreceptors control plant growth, development, and the shade avoidance
response that limits crop yield in high-density agricultural plantings. Cyanobacteriochromes …

This perspective article highlights the challenges in the theoretical description of
photoreceptor proteins using multiscale modeling, as discussed at the CECAM workshop in …

The cyanobacteriochrome Slr1393 can be photoconverted between a red (Pr) and green
absorbing form (Pg). The recently determined crystal structures of both states suggest a …

There have been numerous efforts, both experimental and theoretical, that have attempted
to parametrize model Hamiltonians to describe excited state energy transfer in …

Modern biology investigations on phytochromes as near-infrared fluorescent pigments pave
the way for the development of new biosensors, as well as for optogenetics and in vivo …

Cyanobacteriochromes are compact and spectrally diverse photoreceptor proteins that bind
a linear tetrapyrrole as a chromophore. They show photochromicity by having two stable …

The tetrapyrrole chromophore biliverdin IXα (BV) in the bacteriophytochrome from
Deinococcus radiodurans (DrBphP) is usually assumed to be fully protonated, but this …

We present structural information for oat phyA3 in the far-red-light-absorbing (Pfr) signaling
state, to our knowledge the first three-dimensional (3D) information for a plant phytochrome …
