Summary
Plants use long-range mobile hormones to coordinate organ growth. This review highlights a novel hormone regulating shoot branching and a root signal influencing leaf development.
Area of Science:
- Plant biology
- Developmental biology
- Hormonal signaling
Background:
- Multicellular organisms rely on inter-organ communication.
- Plants utilize long-range signals for growth and development regulation.
Purpose of the Study:
- To review the role of long-range mobile hormones in plant development.
- To highlight two specific examples of hormonal signaling in plants.
Main Methods:
- Literature review of plant hormonal signaling.
- Focus on two case studies: shoot branching and leaf development.
Main Results:
- Identification of a novel, upwardly mobile hormone controlling shoot branching.
- Characterization of a root-derived hormone regulating leaf development.
Conclusions:
- Long-range hormonal communication is crucial for plant organ development.
- Specific mobile hormones mediate complex processes like shoot branching and leaf development.

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...
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.

02:12Short-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.
01:23Overview of Cell Signaling
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate with the environment.
Cells respond to many types of information, often through receptor proteins positioned on the membrane. For example, skin cells respond to and transmit touch...

01:32Types of Signaling Molecules
In multicellular organisms, many molecules transmit signals between cells to pass information. These signals vary in complexity and include small peptides, nucleotides, steroids, fatty acid derivatives, and dissolved gases such as nitric oxide. Some signaling molecules diffuse through the plasma membrane to act locally between neighboring cells or travel long distances. Others remain attached to the cell surface, transmitting information to other cells only when they make contact. In some...
