Phytochrome interacting factors 4 and 5 redundantly limit seedling de-etiolation in continuous far-red light. [PDF]

open access: yes, 2009
Phytochromes are red/far-red photosensors that regulate numerous developmental programs in plants. Among them, phytochrome A (phyA) is essential to enable seedling de-etiolation under continuous far-red (FR) light, a condition that mimics the environment

Light-responsive expression atlas reveals the effects of light quality and intensity in Kalanchoë fedtschenkoi, a plant with crassulacean acid metabolism. [PDF]

open access: yes, 2020
BackgroundCrassulacean acid metabolism (CAM), a specialized mode of photosynthesis, enables plant adaptation to water-limited environments and improves photosynthetic efficiency via an inorganic carbon-concentrating mechanism.

Ecological Adaptation Mechanisms Underlying Successful Plant Reproduction

open access: yesAdvanced Science, EarlyView.
During floral induction, various environmental and endogenous signals converge to regulate the florigen protein, which is transported from leaves to the SAM to initiate flowering. Within the SAM, a complex network of receptor kinases and small peptides orchestrates floral development with high spatiotemporal precision.

Upregulation of GLRs expression by light in Arabidopsis leaves

open access: yesBMC Plant Biology, 2022
Background Glutamate receptor-like (GLR) channels are plant homologs of iGluRs, animal ionotropic glutamate receptors which participate in neurotransmission. GLRs mediate plant adaptive processes and photomorphogenesis.

Sensing and Filtering Environmental Fluctuations: The Case of Biomolecular Condensates in Plants

open access: yesAdvanced Science, EarlyView.
The diversity of plant condensates reflects constraints of sessile organisms to coordinate postembryonic development with environmental adaptation. This review examines how plants employ condensates to integrate temperature, light, redox, and nutrient signals.

Opto-CD28-REACT: optogenetic co-stimulatory receptor activation on non-engineered human T cells

open access: yesFrontiers in Immunology
T-cell activation is a highly regulated process requiring both antigen recognition via the T-cell receptor (TCR) and co-stimulatory signaling, notably through the co-stimulatory receptor CD28. Here, we introduce an optogenetic platform for reversible and

Allosteric effects of chromophore interaction with dimeric near-infrared fluorescent proteins engineered from bacterial phytochromes [PDF]

open access: yes, 2016
Fluorescent proteins (FPs) engineered from bacterial phytochromes attract attention as probes for in vivo imaging due to their near-infrared (NIR) spectra and use of available in mammalian cells biliverdin (BV) as chromophore.

Reversible Lichtinduzierte Oligomerisierung von Arabidopsis‑Cryptochrom 1 und Antagonismus durch BIC1: Einblicke durch Zeitaufgelöste Native Massenspektrometrie

open access: yesAngewandte Chemie, EarlyView.
Mittels zeitaufgelöster nativer Massenspektrometrie wird der blaulichtabhängige kinetische Mechanismus der Oligomerisierung von Arabidopsis CRY1 aufgedeckt. Die Oligomerisierung verläuft sequenziell von Monomeren über Dimere zu Tetrameren. Während ATP die Assemblierung fördert, inhibiert BIC1 die Tetramerbildung und dissoziiert diese unabhängig von ...

Light and gravity signals synergize in modulating plant development

open access: yesFrontiers in Plant Science, 2014
Tropisms are growth-mediated plant movements that help plants to respond to changes in environmental stimuli. The availability of water and light, as well as the presence of a constant gravity vector, are all environmental stimuli that plants sense and ...

Protein control of photochemistry and transient intermediates in phytochromes

open access: yesNature Communications, 2022
Phytochromes are photoreceptors responsible for sensing light in plants, fungi and bacteria. Here the authors use computational simulations to reveal the molecular mechanism of photoactivation and characterize the involved reaction intermediates.
