We present the draft genome sequence of Collimonas sp. strain H4R21, isolated from the rhizosphere of Fagus sylvatica in the forest experimental site of Montiers (France). This genome features coding capacity for plant growth promotion, such as the ability to solubilize minerals, to produce siderophores and antifungal secondary metabolites.
Keywords: Collimonas; chitin; forest; fungi; mineral weathering; nutrient-poor soil.
