PPKs mediate direct signal transfer from phytochrome photoreceptors to transcription factor PIF3

open access: yesNature Communications, 2017
Phytochrome photoreceptors mediate degradation of PIF transcription factors in the nucleus in response to light. Here Niet al. identify a family of nuclear protein kinases that interact with photoactivated phytochrome B and facilitate phytochrome-induced

Tomato phyE is Required for Shade Avoidance in the Absence of phyB1 and phyB2.

open access: yesFrontiers in Plant Science, 2016
The phytochrome (phy) family of red and far-red photoreceptors provides plants with critical information about their surrounding environment and can signal downstream developmental and physiological changes.

Long-Distance Protonation-Conformation Coupling in Phytochrome Species

open access: yesMolecules, 2022
Phytochromes are biological red/far-red light sensors found in many organisms. The connection between photoconversion and the cellular output signal involves light-mediated global structural changes in the interaction between the photosensory module (PAS-

slim shady is a novel allele of PHYTOCHROME B present in the T‐DNA line SALK_015201

open access: yesPlant Direct, 2021
Auxin is a hormone that is required for hypocotyl elongation during seedling development. In response to auxin, rapid changes in transcript and protein abundance occur in hypocotyls, and some auxin responsive gene expression is linked to hypocotyl growth.

Phytochrome phosphorylation in plant light signaling

open access: yesFrontiers in Plant Science
Plant phytochromes, renowned phosphoproteins, are red and far-red photoreceptors that regulate growth and development in response to light signals. Studies on phytochrome phosphorylation postulate that the N-terminal extension (NTE) and hinge region ...

PIF transcription factors link a neighbor threat cue to accelerated reproduction in Arabidopsis

open access: yesNature Communications, 2019
In plants, phytochrome B senses light cues indicative of neighbouring competitors leading to accelerated flowering. Here the authors show that PHYTOCHROME INTERACTING FACTORs 4, 5 and 7 (PIF4, PIF5 and PIF7) mediate neighbor proximity-induced flowering ...

Arogenate dehydratases: unique roles in light-directed development during the seed-to-seedling transition in Arabidopsis thaliana

open access: yesFrontiers in Plant Science, 2023
The seed-to-seedling transition is impacted by changes in nutrient availability and light profiles, but is still poorly understood. Phenylalanine affects early seedling development; thus, the roles of arogenate dehydratases (ADTs), which catalyze ...

Phytochrome activates the plastid-encoded RNA polymerase for chloroplast biogenesis via nucleus-to-plastid signaling

open access: yesNature Communications, 2019
Light initiates chloroplast biogenesis by controlling gene expression in plastids. Here Yoo et al. show that nuclear phytochrome signaling triggers plastid gene expression via a novel dual-localized protein necessary for nuclear phytochrome signaling and

Phytochrome and ethylene signaling integration in Arabidopsis occurs via the transcriptional regulation of genes co-targeted by PIFs and EIN3

open access: yesFrontiers in Plant Science, 2016
Plant seedlings germinating under the soil are challenged by rough soil grains that can induce physical damage and sudden exposure to light, which can induce photobleaching.

Identification of photoperception and light signal transduction pathways in citrus

open access: yesGenetics and Molecular Biology, 2007
Studies employing model species have elucidated several aspects of photoperception and light signal transduction that control plant development. However, the information available for economically important crops is scarce.
