CLAVATA signaling in plant-environment interactions

Area of Science:

• Plant Biology
• Molecular Signaling
• Environmental Adaptation

Background:

• Plants dynamically adapt to environmental cues through complex cellular signaling pathways.
• Signal integration is crucial for plants facing multiple simultaneous environmental stimuli.
• CLAVATA3/EMBRYO SURROUNDING REGION-related (CLE) peptides are emerging as key players in plant-environment interactions.

Approach:

• This review synthesizes current research on environment-regulated CLE peptides and their functions.
• It examines the perception of CLE signals by CLAVATA receptors.
• The review discusses the integration of environmental signals through CLE-CLAVATA modules.

Key Points:

• CLE peptides are mobile signals induced by diverse biotic and abiotic stimuli.
• CLE peptides are perceived by CLAVATA receptor complexes, often involving CLAVATA1.
• CLE signaling fine-tunes plant-microbe interactions, nutrient balance, and carbon allocation.

Conclusions:

• Environment-induced CLE peptides play diverse roles in modulating plant responses.
• CLAVATA receptors are central to perceiving these environmental signals.
• CLE-CLAVATA signaling modules integrate environmental cues with plant physiology and development.
