Flavobacterium, a member of the Bacteroidota phylum, has been increasingly recognized for its role in plant health and development. While traditionally known as pathogens in aquatic environments, Flavobacterium species have shown potential in promoting plant growth, controlling diseases, and enhancing tolerance to abiotic stress. Recent studies highlight their ecological significance in plant microbiomes, with Flavobacterium species being abundant in the rhizosphere and contributing to plant-beneficial interactions through various mechanisms. Flavobacterium species produce volatile organic compounds, such as 2,4-di-tert-butylphenol, which exhibit antimicrobial activity against plant pathogens. They also provide essential nutrients like nitrogen and phosphorus, and can solubilize phosphorus through alkaline phosphatases. Additionally, Flavobacterium species can produce plant hormones such as auxin and abscisic acid, which aid in plant growth and stress tolerance. These bacteria can also enhance plant immunity by eliciting defense responses through outer membrane vesicles. Flavobacterium species contribute to plant health by promoting growth, controlling diseases, and improving stress tolerance. They can colonize root microbiomes and interact with other microbes to enhance plant defense mechanisms. The type IX secretion system (T9SS) plays a role in root colonization and biofilm formation, facilitating the bacteria's ability to colonize plant tissues. Flavobacterium species also contribute to carbon cycling and nutrient availability in soil environments. Despite their potential, the molecular mechanisms underlying Flavobacterium-plant interactions remain poorly understood. Further research is needed to explore the roles of Flavobacterium species in plant microbiomes, including their ability to colonize plant tissues, interact with other microbes, and contribute to plant health. Advances in metagenomic analysis have highlighted the importance of Flavobacterium in improving host plant health, although more studies are required to fully understand their functions and potential applications in agriculture.Flavobacterium, a member of the Bacteroidota phylum, has been increasingly recognized for its role in plant health and development.
