Streptomyces lividans inhibits the proliferation of the fungus Verticillium dahliae on seeds and roots of Arabidopsis thaliana.

Meschke H, Schrempf H - Microb Biotechnol (2010)

Bottom Line: The extension of hyphae from each individual strain correlates with the reduction of the pectin-containing mucilage-layer.As a result, plants have considerably reduced disease symptoms.As spores of the beneficial S. lividans strain are obtainable in large quantity, its application is highly attractive.

Mentions: Individual seeds of A. thaliana were co‐incubated on agar plates with V. dahliae in the presence of S. lividans. Verticillium dahliae conidia germinated at the seed mucilage, and proliferated to a living hyphae network, which extended (control 70 h, Fig. 6A) additionally towards neighbouring regions of the seed. If the seeds were simultaneously exposed to S. lividans spores and V. dahliae conidia, large masses of S. lividans hyphae proliferated preferentially at and within the mucilage. However, only a few V. dahliae hyphae were detectable, and these were more frequent outside the dense S. lividans hyphae network (Fig. 6B). These results demonstrate that S. lividans considerably hinders the growth of V. dahliae.
