Mechanisms for the formation and maintenance of microhabitat self-organization in the root system of orchid.

Orchid root microhabitat self-organization is driven by complex interactions among roots, soil, microorganisms, and root exudates, forming a dynamic system crucial for orchid ecology.

• Why it matters: Understanding these mechanisms addresses the gap in orchid symbiosis research, which is limited compared to other plants, despite orchids' ecological and ornamental importance.
• What they did: The review synthesizes recent advances in techniques, relationships among orchid roots, rhizosphere soil, microorganisms, and root exudates, and discusses the formation and maintenance of microhabitat self-organization.
• The result: This work proposes concepts and theories for orchid root microhabitat self-organization, offering a foundation for future research, conservation, and resource utilization of orchids.
