Summary
Plants use pattern recognition receptors (PRRs) to detect pathogens and pests, activating immune responses. This review details known PRRs and molecules, highlighting their potential for improving crop disease resistance.
Area of Science:
- Plant immunity
- Molecular biology
- Agriculture
Background:
- Plants possess sophisticated immune systems to defend against pathogens and pests, crucial for ecological and agricultural stability.
- Receptor kinases (RKs) and receptor-like proteins (RLPs) function as pattern recognition receptors (PRRs) in plants.
- PRRs monitor the apoplast for danger signals like pathogen-/microbe-associated molecular patterns (PAMPs/MAMPs) and damage-associated molecular patterns (DAMPs).
Purpose of the Study:
- To comprehensively review known PAMPs/MAMPs and DAMPs recognized by plants.
- To summarize the plant PRRs identified to date.
- To discuss methods for identifying PAMPs/DAMPs and PRRs.
- To highlight the biotechnological potential of PRRs for enhancing crop disease resistance.
Main Methods:
- Literature review of PAMPs/MAMPs and DAMPs.
- Compilation of identified plant PRRs.
- Description of methodologies for PAMP/DAMP and PRR identification.
Main Results:
- Detailed overview of recognized PAMPs/MAMPs and DAMPs in plants.
- Catalog of identified plant PRRs and their functions.
- Summary of various methods employed for discovering PAMPs/DAMPs and PRRs.
Conclusions:
- Plant PRRs are vital for basal and non-host resistance, mediating immunity upon PAMP/DAMP perception.
- Understanding PRRs and their ligands is key to deciphering plant immune signaling.
- PRRs offer significant biotechnological promise for developing durable, broad-spectrum disease resistance in crops.

6.8K
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...

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.

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.

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

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.
