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

Beyond the photocycle-how cryptochromes regulate photoresponses in plants? [PDF]
, 2018 Cryptochromes (CRYs) are blue light receptors that mediate light regulation of plant growth and development. Land plants possess various numbers of cryptochromes, CRY1 and CRY2, which serve overlapping and partially redundant functions in different plant

Immunochemistry of Phytochrome [PDF]
Plant Physiology, 1973 Rabbit antibody was elicited against purified oat phytochrome polypeptides. Immunodiffusion and immunoelectrophoresis indicated the antibody elicited was predominantly a single precipitin system. No antigenic difference was detected between red-absorbing phytochrome and far red-absorbing phytochrome.

Frontiers 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 ...

Shade delays flowering in Medicago sativa [PDF]
, 2019 Shade intolerant plants respond to the decrease in the red (R) to far-red light (FR) ratio (R:FR) occurring under shade by elongating stems and petioles and re-positioning leaves, in a race to out-compete neighbors for the sunlight resource.

Phytochrome Signaling Mechanisms [PDF]
The Arabidopsis Book, 2011 Phytochromes are red (R)/far-red (FR) light photoreceptors that play fundamental roles in photoperception of the light environment and the subsequent adaptation of plant growth and development. There are five distinct phytochromes in Arabidopsis thaliana, designated phytochrome A (phyA) to phyE.

Phytochrome phosphorylation in plant light signaling
Frontiers in Plant SciencePlant 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
Nature 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 ...

Identification of photoperception and light signal transduction pathways in citrus
Genetics 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.
