Recently, Yang et al. (2011) tested a fungicidal activity of an antibacterial compound called Xenocoumacin 1 (Xcn1) from symbiotic bacterium, Xenorhabdus nematophila var. pekingensis against Potato late blight disease causing fungus, Phytophthora infestans. These authors reported that this antibacterial compound strongly inhibits P. infestans mycelium growth and sporangia production. Read following papers on antibacterial compounds from entomopathogenic nematode symbiotic bacteria.
