Cell Signaling in Plants01:25

Cell 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...
Plant Hormones01:56

Plant 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.

Defenses Against Pathogens and Herbivores02:26

Defenses Against Pathogens and Herbivores

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.
IP3/DAG Signaling Pathway01:11

IP3/DAG Signaling Pathway

Membrane lipids such as phosphatidylinositol (PI) are precursors for several membrane-bound and soluble second messengers. Specific kinases phosphorylate PI and produce phosphorylated inositol phospholipids. One such inositol phospholipids are the  phosphatidylinositol-4,5 bisphosphate [PI(4,5)P2], present in the inner half of the lipid bilayer. Upon ligand binding, GPCR stimulates Gq proteins to turn on phospholipase Cꞵ. Activated phospholipase Cꞵ cleaves PI(4,5)P2 and produces two-second...
Transgenic Plants02:50

Transgenic Plants

Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Summary

Plants use pattern recognition receptors to detect invaders. Endogenous peptide elicitors, plant-derived molecules, amplify defense responses against pathogens and herbivores, enhancing plant immunity.

  • Immunology
  • Molecular biology

Background:

  • Plant defense relies on pattern recognition receptors sensing microbial and herbivore molecules.
  • Plants also utilize endogenous elicitors, including peptides, to amplify defense responses.
  • These endogenous signals contribute to both local and systemic immunity.

Purpose of the Study:

  • To review the five known endogenous peptide elicitor families in plants.
  • To summarize the properties and functions of these peptide elicitors.
  • To identify future research directions for understanding plant innate immunity.

Main Methods:

  • Literature review of existing research on endogenous peptide elicitors.
  • Analysis of properties and biological roles of identified peptide families.
  • Synthesis of current knowledge and identification of research gaps.

Main Results:

  • Five distinct families of endogenous peptide elicitors have been identified across plant species.
  • These peptides play a crucial role in regulating plant immunity against diverse threats.
  • Their function in activating defense mechanisms is increasingly recognized.

Conclusions:

  • Endogenous peptide elicitors are vital components of the plant immune system.
