Summary
RD21-like proteases regulate plant immunity against pathogens. Pathogen effectors target these proteases, offering new strategies for crop protection.
Area of Science:
- Plant biology
- Molecular biology
- Biochemistry
Background:
- Proteases are key regulators of plant immune responses.
- RD21-like papain-like cysteine proteases with granulin domains are crucial but named differently across species.
- These proteases play a significant role in plant defense mechanisms.
Purpose of the Study:
- To review the background, regulation, and localization of RD21-like proteases.
- To highlight their function in plant immunity.
- To discuss pathogen effector interactions and future crop protection strategies.
Main Methods:
- Literature review of existing studies on RD21-like proteases.
- Analysis of protease function in plant immunity.
- Examination of pathogen effector mechanisms targeting plant proteases.
Main Results:
- RD21-like proteases are essential for plant immunity against diverse pathogens.
- Pathogen-secreted effectors frequently target RD21-like proteases, causing inactivation, mislocalization, or degradation.
- These interactions reveal vulnerabilities in plant defense systems.
Conclusions:
- RD21-like proteases are critical components of plant immunity.
- Understanding effector-protease interactions is key to developing novel crop protection strategies.
- Targeting these proteases offers a promising avenue for enhancing plant disease resistance.

23.1K
Plants present a rich source of nutrients for many organisms, making it a target for herbivores and infectious agents. Plants, though lacking a proper immune system, have developed an array of constitutive and inducible defenses to fend off these attacks.

01:25Cell Signaling in Plants
5.6K
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...

2.6K
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,...

The plant cell wall gives plant cells shape, support, and protection. As a cell matures, its cell wall specializes according to the cell type. For example, the parenchyma cells of leaves possess only a thin, primary cell wall.

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.
