Summary
Plant lectins are carbohydrate-binding proteins crucial for plant immunity. Many function as lectin receptor-like kinases (LecRLK) at the cell surface, acting as pattern-recognition receptors (PRR) to detect threats and trigger defense responses.
Area of Science:
- Plant biology
- Molecular biology
- Biochemistry
Background:
- Lectins are proteins that bind carbohydrates and play diverse biological roles.
- In plants, lectins are found as cell surface receptor kinases (LecRLK) and secreted proteins.
- These lectins are integral to plant defense and stress signaling mechanisms.
Purpose of the Study:
- To provide a general overview of plant lectins.
- To highlight the role of lectins at the plant cell surface.
- To discuss their function in plant immunity and stress response.
Main Methods:
- Literature review of plant lectin research.
- Focus on lectin receptor-like kinases (LecRLK) and secreted lectins.
- Analysis of their involvement in pattern recognition and defense signaling.
Main Results:
- Plant lectins, particularly LecRLKs, function as pattern-recognition receptors (PRR).
- They enable plants to perceive external threats and initiate defense.
- Secreted lectins are also implicated in stress signaling and plant defense.
Conclusions:
- Plant lectins are vital components of the plant immune system.
- LecRLKs at the cell surface are key players in threat perception.
- Lectins contribute significantly to plant stress tolerance and defense.

Cell adhesion is an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain,...

Plants have rigid cell walls that are made up of cell wall polysaccharides that mediate cell-cell adhesion. The primary cell walls of plants consist of two independent and interacting polysaccharide networks: a pectin matrix that embeds the second network comprising cellulose and hemicelluloses.
Pectins are complex heteropolymers mainly composed of negatively-charged α-D-glucopyranosyl uronic acid and some neutral glycosyl residues such as α-L-rhamnopyranose, α-L-arabinofuranose,...

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...

52.1K
Hormones—or any molecule that binds to a receptor, known as a ligand—that are lipid-insoluble (water-soluble) are not able to diffuse across the cell membrane. In order to be able to affect a cell without entering it, these hormones bind to receptors on the cell membrane. When a first messenger, a hormone, binds to a receptor, a signal cascade is set off, causing second messengers, proteins inside the cell, to become activated, resulting in downstream effects.

Cell-surface receptors, also known as transmembrane receptors, are cell surface, membrane-anchored (integral) proteins that bind to external ligand molecules. This type of receptor spans the plasma membrane and performs signal transduction, converting an extracellular signal into an intracellular signal. Ligands that interact with cell-surface receptors do not have to enter the cell that they affect. Cell-surface receptors are also called cell-specific proteins or markers because they are...

Cell adhesion molecules (CAMs) are pivotal to multicellularity and the coordinated functioning of tissues and organ systems. They enable physical interactions between cells and provide mechanical strength to tissues. They also function as receptors for signal transmission across the plasma membrane. The CAMs are broadly classified into four families - integrins, cadherins, selectins, and immunoglobulin-like CAMs (IgCAMs).
