Microorganisms form significant interactions with a wide
array of biota in terrestrial ecosystems, often with important
consequences for all species present. Terrestrial plant species are
colonized by a large number of microorganisms in several
morphological regions, including interior tissues (endophytes), on
their leaves (epiphytes) and in their rhizosphere. In the rhizosphere,
the microbial genes greatly outnumber the plant genes (Mendes
et al., 2013), resulting in a microbiome that has been referred to
different microbial community. Other factors such as xenobiotics
can disturb the rhizosphere conditions, having both direct and indirect
consequences for the plant and its microbial community.
