The G123 rice mutant, carrying a mutation in SE13, presents alterations in the expression patterns of photosynthetic and major flowering regulatory genes.

PLoS ONE, 2020
Day length is a determinant of flowering time in rice. Phytochromes participate in flowering regulation by measuring the number of daylight hours to which the plant is exposed. Here we describe G123, a rice mutant generated by irradiation, which displays

MYB Factors: Hubs of Plant Stress and Hormone Crosstalk

Plant Biotechnology Journal, EarlyView.
ABSTRACT MYB transcription factors function as main regulatory hubs that integrate environmental signals with multi‐hormonal pathways to synchronize plant growth, metabolism and stress responses. This review delineates the regulatory roles of MYB in the signalling pathway of salicylic acid, jasmonic acid, ethylene and abscisic acid signalling.

Cytoplasmic Phytochrome Action [PDF]

Plant and Cell Physiology, 2010
Phytochrome photoperception is a common mechanism for the detection of red and far-red light in bacteria, cyanobacteria, fungi and plants. However, the responses following phytochrome activation appear to be quite diverse between species. Lower plants, such as mosses, show phytochrome-mediated directional responses, namely phototropism and ...

Multi‐Induction Strategies in Crops: Mechanisms, Synergistic Effects, and Sustainable Applications for Enhanced Secondary Metabolite Production

Food Frontiers, Volume 7, Issue 4, July 2026.
This review analyzes single/combined abiotic (light, water, nutrients, hormones) and biotic (microbes, yeast) elicitors regulating signaling, gene expression, and metabolism to boost plant secondary metabolites. It highlights synergistic multielicitor strategies for crop quality and functional foods, while critically addressing current limitations and ...

Plant Phytochromes and their Phosphorylation [PDF]

International Journal of Molecular Sciences, 2019
Extensive research over several decades in plant light signaling mediated by photoreceptors has identified the molecular mechanisms for how phytochromes regulate photomorphogenic development, which includes degradation of phytochrome-interacting factors (PIFs) and inactivation of COP1-SPA complexes with the accumulation of master transcription factors ...

Es werde Licht! Licht als Antrieb und Regulator in synthetischen Zellen

Angewandte Chemie, Volume 138, Issue 24, 8 June 2026.
Zellen sind Systeme außerhalb des Gleichgewichts, die ihre Eigenschaften in Raum und Zeit regulieren. In biomimetischen synthetischen Zellen bietet Licht eine einzigartige Möglichkeit, Vorgänge räumlich und zeitlich anzutreiben und zu kontrollieren.

Partial Proteolysis of Rice Phytochrome: Comparison with Oat Phytochrome

Zeitschrift für Naturforschung C, 1989
Phytochrome was isolated from etiolated rice seedlings (Oryza sativa L.) by slight modification of the procedure for oat phytochrome. Spectral data of rice phytochrome are comparable with those of oat and rye phytochrome. Controlled proteolysis with endoproteinases Lys-C and Glu-C yielded defined fragments some of which were different for Pr and Pfr ...

Let There be Light! Light as an Engine and Regulator in Synthetic Cells

Angewandte Chemie International Edition, Volume 65, Issue 24, 8 June 2026.
Cells are out‐of‐equilibrium systems that regulate their spatiotemporal features. In biomimetic synthetic cells, light offers a unique way for energizing and regulating events in space and time. This review explores the implementation of light‐responsive tools in synthetic cells to replicate biological functions and enable new bioinspired behaviors ...

Light-induced structural changes in a monomeric bacteriophytochrome

Structural Dynamics, 2016
Phytochromes sense red light in plants and various microorganism. Light absorption causes structural changes within the protein, which alter its biochemical activity.
