Primary Processes During the Light‐signal Transduction of Phototropin [PDF]

open access: yesPhotochemistry and Photobiology, 2007
AbstractPhototropin is a blue‐light photoreceptor in plants that mediates phototropism, chloroplast relocation, stomata opening and leaf expansion. Phototropin molecule has two photoreceptive domains named LOV1 (light–oxygen–voltage) and LOV2 in the N‐terminus and a serine/threonine kinase domain in the C‐terminus, and acts as a blue light‐regulated ...

Blue Light Receptors and Signal Transduction [PDF]

open access: yesThe Plant Cell, 2002
A plant blue light response was documented as early as 1881 by Darwin when he discovered what is now known as the blue light–induced phototropic response ([Darwin, 1881][1]). However, blue light receptors mediating phototropism and other photoresponses in plants have remained elusive ...

How and why do roots sense light under the soil surface?

open access: yesFrontiers in Plant Science, 2015
Light can penetrate several centimetres below the soil surface. Growth, development and behaviour of plant roots are markedly affected by light despite their underground lifestyle.

FMO1 Is Involved in Excess Light Stress-Induced Signal Transduction and Cell Death Signaling

open access: yesCells, 2020
Because of their sessile nature, plants evolved integrated defense and acclimation mechanisms to simultaneously cope with adverse biotic and abiotic conditions.

Light Detection and Signal Transduction in the BLUF Photoreceptors [PDF]

open access: yesPlant and Cell Physiology, 2012
BLUF (sensor of blue light using FAD) domain-containing proteins are one of three types of flavin-binding, blue-light-sensing proteins found in many bacteria and some algae. The other types of blue-light-sensing proteins are the cryptochromes and the light, oxygen, voltage (LOV) domain-containing proteins.

Phosphate sink containing two-component signaling systems as tunable threshold devices [PDF]

open access: yes, 2014
Synthetic biology aims to design de novo biological systems and reengineer existing ones. These efforts have mostly focused on transcriptional circuits, with reengineering of signaling circuits hampered by limited understanding of their systems dynamics ...

Studies of the light-induced signal transduction in Agrobacterium fabrum

open access: yes, 2021
Organisms regardless of their origin or type, monitor their environment and respond differently to any environmental changes that occur. These changes not only can alter biochemical reactions that are taking part in the signal transmission, but also the ...

Dissecting long-term adjustments of photoprotective and photo-oxidative stress acclimation occurring in dynamic light environments

open access: yesFrontiers in Plant Science, 2016
Changes in light intensity directly affect the performance of the photosynthetic apparatus. Light energy absorbed in excess of cells’ needs leads to production of reactive oxygen species and photo-oxidative damage.

regO: a novel locus in the regulation of tetrapyrrole biosynthesis in Rhodospirillum rubrum

open access: yesAnnals of Microbiology, 2023
Purpose A new locus, regO, involved in the regulation of photosynthesis gene expression in response to oxygen and light, has been studied in Rhodosprillum rubrum ATCC1117 (Rsp. rubrum) for identification of its function.
