Fungal endophytes, a diverse group of ascomycetous fungi
defined functionally by their occurrence within asymptomatic tissues
of plants, have been found in all plant families (Arnold, 2007).
Likewise, a wide range of bacterial genera can be isolated from surface
disinfected plant tissues or extracted from inner plants parts
(Chanway, 1988; Hallmann et al., 1997; Quadt-Hallmann et al.,
1997).
