Abstract
[EN] Verticillium wilt is a soil-borne fungal disease that affects olive trees (Olea europaea) and
poses a serious threat to their cultivation. The causal agent of this disease is Verticillium dahliae, a
pathogen that is difficult to control with conventional methods. Therefore, there is a need to explore
alternative strategies for the management of Verticillium wilt. In this study, we aimed to isolate and
characterize actinobacteria from the rhizosphere of olive trees that could act as potential biocontrol
agents against V. dahliae. We selected a Streptomyces sp. OR6 strain based on its in vitro antifungal
activity and its ability to suppress the pathogen growth in soil samples. We identified the main active
compound produced by this strain as albocycline, a macrolide polyketide with known antibacterial
properties and some antifungal activity. Albocycline was able to efficiently suppress the germination
of conidiospores. To our knowledge, this is the first report of albocycline as an effective agent against
V. dahliae. Our results suggest that Streptomyces sp. OR6, or other albocycline-producing strains, could
be used as a promising tool for the biological control of Verticillium wilt.
