Phylum Cnidaria occupies an early branching position in the evolution of eukaryotes, establishing both close and distant relationships with most other eukaryotic metazoans. Budding encompasses the complete processes of cell proliferation, differentiation, and tissue regeneration, making it an ideal model for exploring various aspects of cellular function and evolution. Additionally, budding serves as the primary reproductive method for increasing the cnidarian population. This asexual reproductive phase is critical for managing and mitigating cnidarian outbreaks. This paper summarizes the common factors influencing budding, the signaling pathways involved and their associated functions, and the methodologies employed in relevant research, providing a theoretical foundation for the prevention and control of cnidarian populations.
