Summary
FLOWERING LOCUS T (FT) and related proteins are key long-distance signals for flowering in plants. This review synthesizes research on various regulators, including gene products and hormones, influencing this crucial developmental transition.
Area of Science:
- Plant Biology
- Molecular Biology
- Developmental Biology
Background:
- The FLOWERING LOCUS T (FT) protein and its paralogs are recognized as critical long-distance floral stimulus components in many plant species.
- Extensive research has focused on the physiological and molecular mechanisms controlling plant developmental transitions, generating a vast dataset.
Purpose of the Study:
- To provide a comprehensive overview of recent research on florigenic and antiflorigenic regulators.
- To synthesize findings on gene products, phytohormones, and metabolites involved in plant flowering regulation.
Main Methods:
- Literature review and synthesis of existing research data.
- Analysis of studies identifying systemic florigenic and antiflorigenic regulators.
Main Results:
- Identification of multiple systemic regulators of flowering, including FT proteins, other gene products, phytohormones, and metabolites.
- Evidence supporting the role of FT and its paralogs as integral parts of the floral stimulus.
Conclusions:
- FT proteins and related molecules play a significant role in mediating flowering time through long-distance signaling.
- Understanding these regulators is crucial for deciphering plant developmental transitions and optimizing crop yields.

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...
02:00Photoreceptors 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.
02:12Short-distance Transport of Resources
Short-distance transport refers to transport that occurs over a distance of just 2-3 cells, crossing the plasma membrane in the process. Small uncharged molecules, such as oxygen, carbon dioxide, and water, can diffuse across the plasma membrane on their own. In contrast, ions and larger molecules require the assistance of transport proteins due to their charge or size. Transport across membranes also occurs within individual cells, playing a variety of essential roles for the plant as a whole.
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.
02:19Morphogenesis
Plant morphogenesis—the development of a plant’s form and structure—involves several overlapping developmental processes, including growth and cell differentiation. Precursor cells differentiate into specific cell types, which are organized into the tissues and organ systems that make up the functional plant.
01:09Microbe-Plant Interactions
Microbe-plant interactions represent a dynamic spectrum of associations shaped by intricate chemical signaling. These interactions can be neutral, beneficial, or detrimental, and profoundly influence plant physiology, growth, and ecosystem function. The plant microbiome, comprising bacteria, fungi, archaea, protists, and viruses, plays a pivotal role in mediating these effects through surface colonization, internal colonization, or systemic symbiosis.Mutualistic associations, particularly with...
