Streptomyces sp. AcH 505 Genome sequencing and assembly

Numerous lineages of bacteria including the streptomycetes associate with mycorrhizas. Some of these strains are implicated in the stimulation of mycorrhiza formation and termed as mycorrhiza helper bacteria (MHB). The MHB Streptomyces sp. strain AcH 505 stimulates fungal growth by the metabolite auxofuran, promotes mycorrhiza formation by enhancing root colonisation by fungi and stimulates plant root branching, but also elicits a systemic defense response against powdery mildew.
