Scientists sequenced the complete genome of Cordyceps javanica, a fungus used to control pest insects. They discovered that this fungus has an expanded family of 27 chitinase genes (GH18), which are enzymes that help the fungus penetrate insect exoskeletons. These genes show strong evolutionary conservation and stability, making them valuable for developing more effective natural pesticides and understanding how fungal biocontrol agents work.

Scientists studied two enzyme genes in a fungus that eats other harmful fungi. When they removed one gene at a time, the fungus still worked fine. But when they removed both genes together, the fungus grew slower and couldn’t attack its target fungus as effectively. This shows that these genes work together as a team to help the fungus do its job as a natural pest control agent.
