Physiological and transcriptional analyses of Arabidopsis primary root growth in response to phosphate starvation under light and dark conditions

Frontiers in Plant Science
Plants cope with Pi deficiency by triggering an array of adaptive responses, including the remodeling of root system architecture (RSA). Arabidopsis thaliana grown on a Pi-deficient (-Pi) medium in transparent Petri dishes exhibits an inhibition of ...

The ZmCOP1s–ZmCOL3 Module Enhances Late Flowering, Grain Yield and Grain Quality in Maize

Plant Biotechnology Journal, EarlyView.
ABSTRACT Flowering time is a key determinant of yield and regional adaptation in crops and is largely controlled by light signalling. In this study, we identified two maize orthologs of Arabidopsis CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1), designated ZmCOP1a and ZmCOP1b, which activate light signalling and reduce plant height. Loss‐of‐function mutants of

Blue light modulates the interactive effects of far-red light and day–night temperature difference on the growth, morphology and physiology of arugula and lettuce

Frontiers in Plant Science
IntroductionFar-red (FR; 700–800 nm) light and the difference between day and night temperature (DIF) interactively regulate plant morphology and growth. FR light and +DIF synergistically promote stem elongation, often reducing leaf expansion and overall

Orientations and water dynamics of photoinduced secondary charge-separated states for magnetoreception by cryptochrome

Communications Chemistry, 2021
Cryptochromes are photoreceptors involved in biological magnetoreception, but the interplay of conformation, electronic coupling, and molecular motion remains poorly understood.

Phytochrome A mediates blue-light enhancement of second-positive phototropism in Arabidopsis [PDF]

, 2016
Hypocotyl phototropism of etiolated Arabidopsis seedlings is primarily mediated by the blue-light receptor kinase phototropin 1 (phot1). Phot1-mediated curvature to continuous unilateral blue light irradiation (0.5 µmol m-2 s-1) is enhanced by overhead ...

Engineered Production of Hydroxycinnamoyl Tyramine Conjugates Limits the Growth of the Pathogen Pseudomonas syringae in Arabidopsis

Plant, Cell &Environment, EarlyView.
ABSTRACT Hydroxycinnamoyl tyramine conjugates are phenolamides produced by plants in response to pathogen attack and biotic stresses. Their proposed mechanisms of action include cytotoxicity towards pathogens, cell wall reinforcement to restrict pathogen proliferation, and signaling activity to trigger general stress responses.

Structure and Function of Animal Cryptochromes [PDF]

Cold Spring Harbor Symposia on Quantitative Biology, 2007
Cryptochrome (CRY) is a photolyase-like flavoprotein with no DNA-repair activity but with known or presumed blue-light receptor function. Animal CRYs have DNA-binding and autokinase activities, and their flavin cofactor is reduced by photoinduced electron transfer.

Gibberellin and auxin influence the diurnal transcription pattern of photoreceptor genes via CRY1a in tomato.

PLoS ONE, 2012
BackgroundPlant photoreceptors, phytochromes and cryptochromes, regulate many aspects of development and growth, such as seed germination, stem elongation, seedling de-etiolation, cotyledon opening, flower induction and circadian rhythms.
