Phoma  stem canker (caused by the ascomycetes  Leptosphaeria maculans and Leptosphaeria biglobosa ) is an important disease of oilseed rape. Its effect on endophyte communities in roots and shoots and the potential of endophytes to promote growth and control diseases of oilseed rape (OSR) was investigated.  Phoma  stem canker had a large effect especially on fungal but also on bacterial endophyte communities. Dominant bacterial genera were  Pseudomonas , followed by  Enterobacter ,  Serratia ,  Stenotrophomonas ,  Bacillus  and  Staphylococcus .  Achromobacter ,  Pectobacter  and  Sphingobacterium  were isolated only from diseased plants, though in very small numbers. The fungal genera  Cladosporium ,  Botrytis  and  Torula  were dominant in healthy plants whereas  Alternaria ,  Fusarium  and  Basidiomycetes  ( Vishniacozyma ,  Holtermaniella ,  Bjerkandera / Thanatephorus ) occurred exclusively in diseased plants. Remarkably,  Leptosphaeria biglobosa  could be isolated in large numbers from shoots of both healthy and diseased plants. Plant growth promoting properties (antioxidative activity, P-solubilisation, production of phytohormones and siderophores) were widespread in OSR endophytes. Although none of the tested bacterial endophytes ( Achromobacter, Enterobacter ,  Pseudomonas ,  Serratia  and  Stenotrophomonas ) promoted growth of oilseed rape under P-limiting conditions or controlled  Phoma  disease on oilseed rape cotyledons, they significantly reduced incidence of  Sclerotinia  disease. In the field, a combined inoculum consisting of  Achromobacter piechaudii , two pseudomonads and  Stenotrophomonas rhizophila  tendencially increased OSR yield and reduced  Phoma  stem canker.
