Insect pathogenic bacterium also helps to combat fungal infection

The secondary cell type of Photorhabdus luminescens protects plants against the pathogenic fungus Fusarium graminearum. The associated bacteria not only safeguard plants but also kill this funs using enzymes that degrade chitin (right). Without protection, the infected plant will wither and possibly even die (left).
