Summary
Plant 14-3-3 proteins regulate diverse physiological functions by binding to phosphorylated proteins. This review highlights their crucial roles in environmental stress, pathogen defense, light responses, metabolism, hormone signaling, and growth.
Area of Science:
- Plant molecular biology
- Plant signaling pathways
- Protein-protein interactions
Background:
- Plant 14-3-3 proteins are highly conserved, functioning by binding to phosphorylated client proteins.
- They regulate a wide array of proteins, influencing diverse physiological processes in plants.
- 14-3-3s are responsive to both extracellular and intracellular environmental cues.
Purpose of the Study:
- To review the emerging roles of plant 14-3-3 proteins.
- To cover their involvement in environmental responses, including stress, pathogens, and light.
- To discuss their potential roles in primary metabolism, hormone signaling, growth, and cell division.
Main Methods:
- Literature review of existing research on plant 14-3-3 proteins.
- Analysis of studies detailing 14-3-3 interactions with client proteins.
- Synthesis of findings on 14-3-3s' regulatory functions in various plant processes.
Main Results:
- Plant 14-3-3s modulate signaling pathways responding to environmental inputs.
- They play key roles in plant defense against pathogens and adaptation to environmental stress.
- Emerging evidence points to significant roles in primary metabolism, hormone signaling, and developmental processes.
Conclusions:
- Plant 14-3-3 proteins are central regulators of plant physiology and environmental responses.
- Their versatility makes them critical for plant survival, growth, and adaptation.
- Further research into 14-3-3 functions will uncover deeper insights into plant biology.

01:25Cell Signaling in Plants
Plant cells communicate to coordinate their cycle of growth, flowering and fruiting, and activities in roots, shoots, and leaves in response to the changing environmental conditions. Plant signaling is distinct from animal signaling. Plants primarily utilize enzyme-linked receptors, whereas the largest class of cell-surface receptors in animals are G-protein coupled receptors (GPCRs). Unlike animals, receptor tyrosine kinases are rare in plants. Instead, plants have a diverse class of...
02:35Key Elements for Plant Nutrition
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the atmosphere, the...
02:45Responses to Heat and Cold Stress
Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.
01:56Plant 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.
