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: Seeds were placed onto agar plates, and were incubated alone or together in different combinations with the microorganisms. In the absence of any microorganism (Fig. 8A, controls), seedlings with green leaves, a short stem and long, barely branching roots were detected. If seeds had been incubated with spores of S. lividans, the resulting seedlings (Fig. 8B) resembled those of the control (Fig. 8A). In contrast, the presence of V. dahliae provoked the generation of seedlings with a varying degree of atrophy symptoms including chlorotic or barely developed leaves, and reduced or marginal stems and roots (Fig. 8C). The co‐presence of S. lividans with V. dahliae led to seedlings with green leaves (Fig. 8D).
