Far-red Fraction: An Improved Metric for Characterizing Phytochrome Effects on Morphology

open access: yesJournal of the American Society for Horticultural Science, 2020
Phytochrome, a well-studied photoreceptor in plants, primarily absorbs in the red (R) and far-red (FR) regions and is responsible for the perception of shade and subsequent morphological responses.

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-

Phytochrome Control of Another Phytochrome-mediated Process [PDF]

open access: yesPlant Physiology, 1972
The phytochrome-mediated attachment of root tips of mung bean (Phaseolus aureus) and barley (Hordeum vulgare) to glass is affected by the prior exposure of hydrated seeds or seedlings to red or far red radiation. Prior irradiation of seeds or seedlings of mung bean with red light promotes attachment, while far red light promotes detachment of root tips.

DOF AFFECTING GERMINATION 2 is a positive regulator of light-mediated seed germination and is repressed by DOF AFFECTING GERMINATION 1 [PDF]

open access: yes, 2015
BACKGROUND: The transcription factor DOF AFFECTING GERMINATION1 (DAG1) is a repressor of the light-mediated seed germination process. DAG1 acts downstream PHYTOCHROME INTERACTING FACTOR3-LIKE 5 (PIL5), the master repressor, and negatively regulates ...

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.
