Summary
CLAVATA3 (CLV3)/EMBRYO SURROUNDING REGION (ESR) (CLE) peptides regulate plant development, including shoot and root growth. These signaling molecules also play a role in plant defense against nematode infections.
Area of Science:
- Plant molecular biology
- Plant development
- Plant-pathogen interactions
Background:
- CLAVATA3 (CLV3)/EMBRYO SURROUNDING REGION (ESR) (CLE) genes encode small secreted peptide hormones crucial for plant development.
- The first Arabidopsis CLE gene was identified from clv3 mutants, which display stem fasciation and increased floral organs.
- 32 CLE genes are found in Arabidopsis, with CLV3 and CLE40 regulating shoot apical meristem (SAM) and root columella initial cell activity by repressing WUSCHEL (WUS) and WUSCHEL-related homeobox 5 (WOX5) gene expression.
Purpose of the Study:
- To review the diverse functions and activities of CLE peptides in plant development.
- To highlight the role of CLE peptides in shoot, root, and vascular development.
- To discuss the significance of CLE peptides in plant interactions with phytoparasitic nematodes.
Main Methods:
- Literature review of recent research on CLE peptides.
- Analysis of CLE peptide functions in various plant developmental processes.
- Examination of CLE peptide involvement in plant-nematode interactions.
Main Results:
- CLE signaling pathways are conserved across plant species.
- CLE peptides are involved in regulating shoot, root, and vascular development.
- CLE peptides play a critical role in plant defense against phytoparasitic nematodes.
Conclusions:
- Understanding CLE peptide molecular properties and mechanisms offers insights into plant cell-cell communication.
- Further research can leverage this knowledge to manipulate plant-nematode interactions for agricultural benefit.

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...
01:09Microbe-Plant Interactions
Microbe-plant interactions represent a dynamic spectrum of associations shaped by intricate chemical signaling. These interactions can be neutral, beneficial, or detrimental, and profoundly influence plant physiology, growth, and ecosystem function. The plant microbiome, comprising bacteria, fungi, archaea, protists, and viruses, plays a pivotal role in mediating these effects through surface colonization, internal colonization, or systemic symbiosis.Mutualistic associations, particularly with...
01:12Role Of Notch Signalling In Intestinal Stem Cell Renewal
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

02:26Defenses 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.
03:14Notch Signaling Pathway
The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not until 1985...
