Methylobacterium aquaticum strain MA-22A

Methylobacterium aquaticum strain MA-22A is a rod-shaped bacterium known for its ecological versatility, primarily found in fresh water environments, hydroponic cultures of moss, and on plant surfaces, including the phyllosphere and soil. This strain is characterized by the presence of true flagella, which likely contributes to its mobility in aquatic habitats. Methylobacterium aquaticum MA-22A has two replicons, indicating a complex genomic architecture that may play a role in its adaptability and survival in diverse environments. It has been identified to interact with specific host plants, including Niphotrichum japonicum and Lemna, suggesting a potential role in plant-associated microbial communities. The strain is cataloged under accessions NZ_AP014704.1 and NZ_AP014709.1, providing a basis for further genomic and functional studies. The presence of Methylobacterium aquaticum MA-22A in hydroponic systems and on plant surfaces indicates its potential utility in agriculture, particularly in enhancing plant growth or health in controlled environments. Ecologically, Methylobacterium species, including MA-22A, are recognized for their contributions to the nitrogen cycle and plant-microbe interactions. The strain's association with plant surfaces may facilitate nutrient exchange or protection against pathogens, underscoring its importance in both natural and agricultural ecosystems.
