Genome-wide analyses of light-regulated genes in Aspergillus nidulans reveal a complex interplay between different photoreceptors and novel photoreceptor functions.

open access: yesPLoS Genetics, 2021
Fungi sense light of different wavelengths using blue-, green-, and red-light photoreceptors. Blue light sensing requires the "white-collar" proteins with flavin as chromophore, and red light is sensed through phytochrome.

Bottom-up Assembly of the Phytochrome Network. [PDF]

open access: yesPLoS Genetics, 2016
Plants have developed sophisticated systems to monitor and rapidly acclimate to environmental fluctuations. Light is an essential source of environmental information throughout the plant's life cycle.

Improving the Predictive Value of Phytochrome Photoequilibrium: Consideration of Spectral Distortion Within a Leaf

open access: yesFrontiers in Plant Science, 2021
The ratio of active phytochrome (Pfr) to total phytochrome (Pr + Pfr), called phytochrome photo-equilibrium (PPE; also called phytochrome photostationary state, PSS) has been used to explain shade avoidance responses in both natural and controlled ...

Phytochrome B photobodies are comprised of phytochrome B and its primary and secondary interacting proteins

open access: yesNature Communications, 2023
Phytochrome is a photoreceptor forming a membraneless organelle called a photobody. The authors isolated the photobody and found that the photobody is made of not only phytochrome but also its primary and secondary interacting proteins.

The protein phosphatase 7 regulates phytochrome signaling in Arabidopsis.

open access: yesPLoS ONE, 2008
The psi2 mutant of Arabidopsis displays amplification of the responses controlled by the red/far red light photoreceptors phytochrome A (phyA) and phytochrome B (phyB) but no apparent defect in blue light perception.

Phytochrome and endogenous gibberellin-like substances in etiolated and irradiated oat seedlings

open access: yesActa Societatis Botanicorum Poloniae, 2014
The level of gibberellin-like substances was investigated in oat coleoptiles with different stationary states of phytochrome and in leaf segments which had been etiolated and irradiated with red light.

Expression dynamics of phytochrome genes for the shade-avoidance response in densely direct-seeding rice

open access: yesFrontiers in Plant Science, 2023
Because of labor shortages or resource scarcity, direct seeding is the preferred method for rice (Oryza sativa. L) cultivation, and it necessitates direct seeding at the current density.

Lack of influence of low temperature, light and growth substances on phytochrome resynthesis in coleoptiles of irradiated oat seedlings

open access: yesActa Societatis Botanicorum Poloniae, 2014
The photoconversion of phytochrome PR into the PFR form causes at the same time the destruction of the initial large fraction of phytochrome found in the coleoptiles of etiolated oat seedlings.

Cucumber leaf necrosis caused by radiation with abrupt increase of far-red component

open access: yesBiologia Plantarum, 2023
Plants exhibit morphological plasticity in response to changes in the proportion of far-red radiation (FR). However, little is known about the response to a sudden increase of FR component. Cucumber seedlings were acclimatized to radiation without FR (FR-

Influence of growth regulators and respiration inhibitors on dark transformation of phytochrome in coleoptiles of oat seedlings

open access: yesActa Societatis Botanicorum Poloniae, 2014
Irradiation with red light leads to the formation of an unstable, undergoing gradual destruction, physiologically active PFR form of phytochrome in the coleoptiles of oat seedlings.
