Herbaspirillum frisingense[3] is a nitrogen-fixing bacterium which was found as an endophyte in C4-fibre plants like prairie cordgrass (Spartina pectinata), Chinese silver grass, (Miscanthus sinensis), Amur silver-grass (Miscanthus sacchariflorus), and Napier grass (Pennisetum purpureum).[4] The specific name frisingense comes from Freising, a town in Germany where H. frisingense was first isolated from prairie cordgrass and Miscanthus plants.[4]
Interaction with Chinese silver grass
In an experiment investigating the interaction between Miscanthus sinensis and Herbaspirillum frisingense, a roughly 20% increase in fresh biomass was observed in M. sinensis following inoculation with H. frisingense.[5] This experiment showed a unique mechanism. Inoculation saw an upregulation in the genes relevant to jasmonate and ethylene production in the plant roots, although the mechanism to this is still unknown.[5] Specifically, H. frisingense was shown to upregulate ethylene receptors and repress ethylene response factors, overall leading to an increase in root growth.[5] Additionally, H. frisingense is known to produce indoleacetic acid (IAA),[6] and was also shown to manage IAA genes, indicating that there is an intricate balance maintained between ethylene and IAA by H. frisingense.[5]
