Photoreceptors and Plant Responses to Light

Photoreceptors and Plant Responses to Light

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.

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists

Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...

Biological Clocks and Seasonal Responses

Biological Clocks and Seasonal Responses

The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

Plant Hormones

Plant Hormones

Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

G-protein Coupled Receptors

G-protein Coupled Receptors

G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

Area of Science:

Plant Biology
Biochemistry

Background:

Serotonin (5-hydroxytryptamine; SER) is a well-known neurotransmitter in vertebrates.
Recent findings indicate the presence of SER in various plant species, suggesting novel physiological roles.

Purpose of the Study:

To review the biosynthesis, localization, and physiological functions of SER in plants.
To elucidate the role of SER in plant morphogenesis and its potential as a plant hormone.
To highlight research gaps and future perspectives on SER in plant physiology and ecology.

Main Methods:

Literature review of existing studies on SER in plants.
Analysis of SER's reported physiological effects, including growth regulation and auxin-like activity.
Synthesis of information on SER localization within plant tissues.

Main Results:

SER is found in diverse plant parts (leaves, stems, roots, fruits, seeds) with varying concentrations.
SER exhibits auxin-like activity, suggesting its function as a plant hormone.
The precise physiological roles of SER in plant growth, flowering, and morphogenesis require further investigation.

Conclusions:

SER plays a significant role in plant morphogenesis and physiology, potentially acting as a plant hormone.
Understanding SER's function is crucial for advancing plant science, particularly in cellular signaling and ecological adaptations.
Further research is warranted to fully elucidate the multifaceted roles of SER in plant ontogeny.
