Plant CLAVATA3/EMBRYO SURROUNDING REGION-RELATED (CLE) peptides are crucial for cell communication. This review explores their vital roles in plant-microbe interactions, including symbiosis and immunity.
Area of Science:
- Plant Biology
- Molecular Biology
- Microbiology
Background:
- Cell-cell communication is fundamental for organismal development and function.
- Secreted peptides act as signaling molecules in eukaryotes.
- CLAVATA3/EMBRYO SURROUNDING REGION-RELATED (CLE) peptides regulate plant stem cell homeostasis.
Purpose of the Study:
- To review the emerging roles of CLE peptide signaling in plant-microbe interactions.
- To highlight CLE peptides' involvement in nodulation, immunity, and arbuscular mycorrhizal symbiosis.
- To provide insights into plant biology and agricultural applications.
Main Methods:
- Literature review and synthesis of existing research on CLE peptides.
- Analysis of studies focusing on plant-microbe interactions mediated by CLE signaling.
- Focus on key areas: nodulation, plant immunity, and arbuscular mycorrhizal fungi symbiosis.
Main Results:
- CLE peptides are involved in trans-kingdom signaling between plants and microbes.
- Evidence shows CLE peptide involvement in symbiotic interactions, such as nodulation and mycorrhizal associations.
- CLE signaling plays a role in modulating plant immune responses to pathogens.
Conclusions:
- CLE peptide signaling is a key regulator in plant-microbe interactions.
- Understanding these pathways can lead to improved agricultural strategies.
- These interactions reveal sophisticated networks balancing plant growth and defense.
