Pine wilt disease (PWD) is a plant disease that causes serious damage to pine trees. PWD occurs when the host plant is infected with pinewood nematode (PWN), Bursaphelenchus xylophilus. In this study, a compound with nematicidal activity was isolated from actinomycetes and its efficacy was investigated in vitro.We screened and selected Streptomyces sp. 680560, which had nematicidal activity against B. xylophilus. Based on 16S rRNA sequence analysis, it showed 99.93% similarity with Streptomyces blastmyceticus NRRB-5480This study was carried out to isolate actinomycete metabolites from pine tree endophytes from various natural environments for control of PWD. A compound with nematicidal activity was isolated from a selected strain and its structure was identified as teleocidin B4. The nematicidal effect of the isolated active substance, teleocidin B4, was confirmed. This is the first report of the effect of teleocidin B4 on B. xylophilus, suggesting its possibility as a PWD control agent. © 2020 Society of Chemical Industry. |
