It is already well known that endophytic microbes, both prokaryotic and eukaryotic, systemically inhabit plants. Numerous studies of the diversity of endophytic microbes in plants suggest that these microbes are diverse enough and occur in high enough numbers as to constitute communities. The number of microbes in plants further suggests that they may be biologically important to plant functions. However, we still know little about the roles that endophytic microbes play in enabling plant growth and development. Several hypotheses, all of which are based on supportive evidence, have been proposed that pose functional ecological roles for endophytes. These hypotheses include, but are not limited to, the following: defensive mutualism; plant growth promotion; stress protection; oxidative stress protection; habitat adaptation; and associative nitrogen fixation .
