WebSome endophytes are thought to help promote the formation of root hairs by triggering root growth and subsequent plant growth. The remaining endophytes, the ones that did not get broken down by superoxide, due to the presence of antioxidants, are the ones that move further up the root tip. They are forced to exit the root.
