Outline
Seagrass meadows play a vital role in protecting marine biodiversity, mitigating ocean acidification, and preventing soil erosion in the coastal ecosystem. However, global climate change and human activities seriously affect the life of seagrass, which cause the widespread degradation of the seagrass and threaten the safety of coastal ecosystems. Recently, the vital value of microorganisms in promoting the energy flow of seagrass meadows and their growth and development has gradually gained attention. Plant growth-promoting microorganisms(PGPM) will play their value in seedling cultivation, plant transplantation, seed planting and other techniques of seagrass meadow restoration. This paper reviewed the research on how microorganisms interacts with seagrass to promote the growth of plants and increase the resistance to abiotic stress. We introduced the mechanism of PGPM to enhance plant stress tolerance under high temperature, high salt, and low light. We propsoed that modern molecular biological technique should be used to screen seagrass PGPM, clarify the colonization site of PGPM, and explore the molecular interaction mechanism between PGPM and seagrass in different environmental conditions. This paper is some advice for promoting the application of PGPM in seagrass meadow restoration and seagrass protection.
