Expression dynamics of phytochrome genes for the shade-avoidance response in densely direct-seeding rice

Frontiers in Plant Science, 2023
Because of labor shortages or resource scarcity, direct seeding is the preferred method for rice (Oryza sativa. L) cultivation, and it necessitates direct seeding at the current density.

Phytochrome and endogenous gibberellin-like substances in etiolated and irradiated oat seedlings

Acta Societatis Botanicorum Poloniae, 2014
The level of gibberellin-like substances was investigated in oat coleoptiles with different stationary states of phytochrome and in leaf segments which had been etiolated and irradiated with red light.

Cucumber leaf necrosis caused by radiation with abrupt increase of far-red component

Biologia Plantarum, 2023
Plants exhibit morphological plasticity in response to changes in the proportion of far-red radiation (FR). However, little is known about the response to a sudden increase of FR component. Cucumber seedlings were acclimatized to radiation without FR (FR-

Lack of influence of low temperature, light and growth substances on phytochrome resynthesis in coleoptiles of irradiated oat seedlings

Acta Societatis Botanicorum Poloniae, 2014
The photoconversion of phytochrome PR into the PFR form causes at the same time the destruction of the initial large fraction of phytochrome found in the coleoptiles of etiolated oat seedlings.

Influence of growth regulators and respiration inhibitors on dark transformation of phytochrome in coleoptiles of oat seedlings

Acta Societatis Botanicorum Poloniae, 2014
Irradiation with red light leads to the formation of an unstable, undergoing gradual destruction, physiologically active PFR form of phytochrome in the coleoptiles of oat seedlings.

Comparative analysis of two phytochrome mutants of tomato (Micro-Tom cv.) reveals specific physiological, biochemical, and molecular responses under chilling stress

Journal of Genetic Engineering and Biotechnology, 2020
Background Phytochromes are plant photoreceptors that have long been associated with photomorphogenesis in plants; however, more recently, their crucial role in the regulation of variety of abiotic stresses has been explored.

Tyrosine 263 in Cyanobacterial Phytochrome Cph1 Optimizes Photochemistry at the prelumi-R→lumi-R Step [PDF]

, 2014
We report a low-temperature fluorescence spectroscopy study of the PAS-GAF-PHY sensory module of Cph1 phytochrome, its Y263F mutant (both with known 3D structures) as well as Y263H and Y263S to connect their photochemical parameters with intramolecular ...
