Summary
Green light (GL) plays a complex role in plant development, contrary to its perceived inefficiency. Understanding GL
Area of Science:
- Plant Biology
- Photomorphogenesis
- Agricultural Science
Background:
- Light is crucial for plant growth, with red light (RL) and blue light (BL) driving photosynthesis.
- Green light (GL) has historically been viewed as less effective for photosynthesis in terrestrial plants.
- GL's role in plant development is complex and often contradictory.
Purpose of the Study:
- To comprehensively review the implications of green light (GL) in plant developmental processes.
- To explore potential photoreceptors mediating GL responses due to the absence of a specific GL receptor.
- To highlight the potential of GL-based optogenetics in smart agriculture.
Main Methods:
- Literature review of existing research on green light's effects on plants.
- Discussion of potential photoreceptor mechanisms for green light perception.
- Exploration of optogenetic applications using green light.
Main Results:
- Green light (GL) influences plant development in ways beyond its photosynthetic efficiency.
- Several photoreceptors may mediate plant responses to green light (GL).
- Green light (GL) offers potential for advanced agricultural technologies.
Conclusions:
- Green light (GL) has significant, albeit complex, roles in plant development.
- Further research into GL photoreceptors is needed.
- GL-based optogenetics presents a promising avenue for smart agriculture.

29.0K
Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

02:16Light Acquisition
9.8K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Most organisms use photoreceptors to sense and respond to light. Examples of photoreceptors include bacteriorhodopsins and bacteriophytochromes in some bacteria, phytochromes in plants, and rhodopsins in the photoreceptor cells of the vertebral retina. The light-sensitive property of these receptors is because of the bound chromophores, such as bilin in the phytochromes and retinal in the rhodopsins.
Rhodopsins belong to the family of cell surface proteins called G-protein coupled receptors,...
