Small peptides: novel targets for modulating plant-rhizosphere microbe interactions

Area of Science:

• Plant-microbe interactions
• Microbial ecology
• Molecular signaling

Background:

• Rhizosphere microbes are vital for plant growth and stress tolerance.
• Plants and microbes use signaling molecules for inter-kingdom communication.
• Small peptides are key intracellular signals in plants and microbes.

Purpose of the Study:

• To review the role of small plant peptides (SPPs) and small microbial peptides (SPMs) in plant-rhizosphere microbe communication.
• To explore potential mechanisms of this bidirectional cross-kingdom signaling.
• To propose leveraging small peptides for holobiont engineering.

Main Methods:

• Literature review of plant-microbe signaling pathways.
• Analysis of the role of small peptides in inter-kingdom communication.
