Seagrass are a kind of monocotyledonous plants growing in marine environments. Microorganisms such as bacteria, fungi, microalgae, archaea and viruses inhabiting seagrass organs and environment play an important role in controlling growth, nutrition and health of seagrass, and maintaining material cycling in seagrass meadows. In this paper, we briefly summarized some recent progresses in studying of microorganisms in seagrass meadows, and discussed the possible directions for future research in this area. Seagrasses microbiome is significantly different from the microbial community in sediment and seawater, which is distributed in discrete and highly heterogeneous ecological niches, and the model remains consistent on a wide geographical scale. It is not controlled by the seagrasses species and sediment types, but mainly depended on the environment and the metabolism of seagrasses. Most seagrass core microbial communities are associated with the sulfur cycle. In the future, methods such as simulation experiment, the ecological model, genome, metagenome, metatranscriptome and metabolome can be used to study diversity, composition, function, colonization and diseases of microorganisms in seagrass meadows. Additionally, it is of great significance to reveal the interrelationships among microorganisms, seagrasses and the environment for the protection of threatened seagrass meadows.
