Microbial endophytes are typically defined as plant
associated microbes that colonize living internal tissues
of plants without causing any visible symptoms or
immediate over-negative effects and can be isolated
from surface disinfected plant tissue [11-13].
Endophytes exist in a range of tissue types within a
broad range of plants, colonizing the plant systemically
with bacterial colonies and biofilms, residing latently in
intercellular spaces, inside the vascular tissue or within
cells [14]. The relatively steady internal environment
inside the plant tissues makes endophytes more
bioactive than the rhizospheric or others plant
associated microorganisms [15]. Endophytic bacteria
resides in the endosphere, the internal
microenvironment of root (endorrhiza), shoot and
leaves hence, these bacteria might interact more closely
with the host plant and therefore, could be efficient
biological control agent in sustainable crop production and offer unique opportunity for crop protection and
