The Gene Expression of the Transcription Factors HY5 and HFR1 Is Involved in the Response of Arabidopsis thaliana to Artificial Sun-like Lighting Systems [PDF]
BiologyPlants can sense light signals using specific photoreceptors, activating light signaling pathways to precisely regulate photomorphogenesis and shade-avoidance responses.

Chromophores in Photomorphogenesis [PDF]
, 1983 Chromophores in photomorphogenesis are those parts of the photoreceptor molecules which absorb the light responsible for the physiological response. Absorption spectra of the chromophores should therefore principally correspond to the action spectra of photomorphoses.

The Arabidopsis Book, 2012 As photoautotrophs, plants are exquisitely sensitive to their light environment. Light affects many developmental and physiological responses throughout plants' life histories. The focus of this chapter is on light effects during the crucial period of time between seed germination and the development of the first true leaves.

Multifaceted roles of BBX transcription factors: impacts on key agronomical traits and environmental resilience. [PDF]
New PhytolSummary B‐box (BBX) proteins were initially characterized as transcription factors connecting light signaling to the regulation of flowering time and seedling photomorphogenesis. However, over the last decade, increasing evidence has shown that they integrate light and hormone signaling, modulating multiple physiological processes during plant life. In

Frontiers in Plant Science, 2022 Light-triggered transcriptome reprogramming is critical for promoting photomorphogenesis in Arabidopsis seedlings. Nonetheless, recent studies have shed light on the importance of alternative pre-mRNA splicing (AS) in photomorphogenesis.

Effect of blue light on endogenous isopentenyladenine and endoreduplication during photomorphogenesis and de-etiolation of tomato (Solanum lycopersicum L.) seedlings. [PDF]
PLoS ONE, 2012 Light is one of the most important factor influencing plant growth and development all through their life cycle. One of the well-known light-regulated processes is de-etiolation, i.e. the switch from skotomorphogenesis to photomorphogenesis. The hormones

Emerging Molecular Links Between Plant Photomorphogenesis and Virus Resistance
Frontiers in Plant Science, 2020 Photomorphogenesis refers to photoreceptor-mediated morphological changes in plant development that are triggered by light. Multiple photoreceptors and transcription factors (TFs) are involved in the molecular regulation of photomorphogenesis.

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 ...
